Exploits on the Internet

I received the above at my work email address last week.....

I have always been unimpressed with the idea of computer hackers for a number of reasons, the most obvious ones are contained in the above email.  Apart from the obvious extortion, their ability reach out and ruin the day for anybody through any number of mechanisms is a major problem.  I was concerned to some degree about the threat based on me watching porn videos because it would be fairly easy to make it appear that I did it using any split screen video app.  Some online research revealed that there is a hack for Mac cameras.  It might be easy to get a video of me on the computer and then pair it with any pornography video.  

My dealing with identity thieves illustrated how easy it is for criminals to remain anonymous in our society while average citizens deal with their mischief.  I was called at work by a very aggressive person working for a collection company who claimed that I owed them $10,000.  Investigation showed that an identity thief opened a fake credit card based on my Social Security Number and ran up the charges.  I filed a police report and was advised by the local police that it was unlikely that anything would happen, but that the report was necessary in order to file an affidavit with the credit card company to avoid paying the charges.  I was eventually able to track the thief to a Florida address and called the local Sheriff to investigate.  I was told that the Sheriff would not look into it because "anybody could have used that mailbox and it would be an invasion of privacy." It became clear that identity theft was just the cost of doing business for credit card companies and credit reporting agencies - regardless of the cost and time to the consumer.

The source of my of the hacking exploitation is infuriating and that of course is poor computer security.  What is never really made explicit is the reason for the lack of security. It was certainly never really designed in.  Apple claims that it is and they have a detailed explanation about this in their literature.  On the other hand Microsoft operating systems dominate the individual and corporate PC worlds.  If you are going where the money is - it will probably involve a Microsoft OS.  It seems that every Microsoft upgrade involves a raft of new security problems and when they have a stable OS - it gets upgraded and the old stable version gets unsupported anyway.  I suppose you can't make a lot of money on a product that you never upgrade. A lot of the security problems rest with the software manufacturers.

There is the software security industry.  Large companies that make antiviruses, firewalls, malware detectors, and pass word managers.  A dizzying array of free and in some cases fairly expensive software with the guarantee that none of it is foolproof - it might not work at all.  As an example, I was looking at the new collection of password managers for keylogger protection.  The above note describes a keylogger and that is software that records your keystrokes and sends them back to the hacker so that they can discover your passwords and account numbers/logins and steal from you.  Keyloggers can also take screen shots to get similar information. The password managers may or may not protect you against that.

The average computer user seems to pay a premium price for a computer with not very good security and an additional price for software that may or may not add much security.

By default we are left with a semblance of security at our own hands.  The common advice is to not open any email from an unknown source.  Email is a common way that malware and viruses are introduced to computers in large systems with extreme results.  It may allow hacker access to information or in the extreme case hijack the entire system until a ransom is paid to unlock it.  In the case of the message sent to me - I am sitting behind a corporate firewall  that seems to intercept even benign messages and send me a report so that I can decide which one should be deleted and which should be released.  This message sailed right through! 

All of the lack of reasonable security results in the possibility of scaling the criminal enterprise.  Now instead of blackmailing a person who may be engaged in some activity that they don't want anyone to know about - the enterprising Internet criminal can send out thousands or tens of thousands of these messages - just playing the odds. The impact on the other 90% is completely ignored.   

All of the security fixes so far ignore the basic problem of who is basically creating all of this chaos. I did an PubMed search on hacker(s) and came up with 90 references dating back to 1986.  None of them were what I would consider to be scientific papers. Most were opinion pieces either warning about threats or advice on how to secure your data or network against threats. Many were from non-mainstream journals.  

I am also a member of the IEEE and when I check their web site, there are 240,000,000 references to hackers.  Hackers psychology as a search term results in 4.182 million references.  Going to the IEEExplore digital library results in 10 hits - 4 from journals and magazines and 6 from conferences.   The professional literature available to me does not seem to be much of an improvement over what is available in the popular press.  In the popular press there are some articles speculating on who the hackers are and what their various motivations are.  For example, an article discusses how some teenage boys become obsessed with hacking and with time and a singular focus can hack like anyone.  There are stories of American teenagers hacking the American government including military institutions and Russian teenagers being praised by Putin for stealing money from American bank accounts.  An article suggests that these teenagers eventually grow out of it when they recognize it is wrong.  One story suggests that the hacking obsessed teens are on the Autism Spectrum - they have Asperger's syndrome.  There are appeals to come up with a multidisciplinary approach to studying hackers and why the social sciences are important in the effort.  There is a suggestion that some of these programs are out there in the security industry and law enforcement - but nothing very compelling.   

Hackers have a large footprint in popular media.  The average television program suggests that a good hacker has instant access to whatever information they need.  That can range from any video feed to any blueprint to any financial information in any city.  That is an obvious stretch, but that is the way things are portrayed.  A study of how many media portrayals are of white hat versus black hat hackers (the old western terminology applies) might be interesting.  My impression is that most are white hat by a large margin.  And then there are the hacker antiheroes, most notably Eliott Alderson of Mr. Robot and his sister Darlene.  Nothing in the media portrayals to suggest that cybercrime in the US costs an estimated $350-500 billion annually.

I sincerely hope that there is a vast network of concerned cybersecurity experts, that are acting rationally on these threats.  I confess that I am not very confident that there is. The idea that a private contractor can access top secret government files and send them around the Internet suggests to me that even our top intelligence agencies may not know much more about protecting their systems than I do. 

Coming back to the graphic, my overriding concern is that there are tens of thousands of people out there like the person that sent this email.  They can get close to many more people than they could walking up to them and holding them up on the street, but that doesn't mean they are any less sociopathic.  The dominant dynamic is that they will verbally, emotionally, or physically intimidate  you to get what they want.  That tone is clearly there in this email.  I think network providers and the hardware and software providers can do a lot more.  The most compelling evidence there is the disappearance of pornographic email spam from the early part of the century. At first it was up to the individual user to set up filters to get rid of it and then mysteriously one day - the inbox was free of pornography for good.  They should be able to do the same thing with emails like the example here.

For now every user must stay diligent and do what they can to protect themselves.  A home network specialist that can be consulted about the latest gear and standards helps.  Common sense helps.  At the bottom rung is the idea that not all emails need to be opened or responded to no matter how obnoxious they are.

Despite the confusing landscape my experience here highlights a couple of points.

1.  It is critical to change your password/login if a business you access on the Internet gets hacked.  In this case the hacker was able to purchase a 2013 password from an Internet site I frequented on the Dark Web and use it in the first line of the email. That password was available because the company I locked into was hacked exposing the personal information of tens of thousands of users.  This highlights the need for changing passwords immediately when there is a report that an online site has been hacked.

2.  In one of the papers I read about password changes - it turns out that frequent password changes required by many companies result in less secure passwords because employees are annoyed by the changes and the suggested complexity of the passwords. The authors of that paper suggested that frequent changes were unnecessary.

I am very interested in any scientific research on the psychology of hacking and cybercriminals.  Please post any good references that you have.

Unsane - It Sure Is

I watch TV while working out - usually Amazon, Netflix, or HBO.  It is all on the Amazon Fire interface.  Today I saw Unsane advertised and despite my aversion to the ongoing One Flew Over The Cuckoo's Nest portrayals of psychiatry - I decided to watch it on the strength of Claire Foy as the leading actor.  Could the actor save the predictable portrayal?  I was skeptical but forged ahead anyway.  The film was a Steven Soderbergh film and I later learned that he shot it on an iPhone 7 Plus.

In the introductory section we learn that the main character Sawyer Valentini (Claire Foy) has moved from Boston to Pennsylvania.  She is a financial analyst in a bank and does financial analysis and reports.  We see her in a contentious phone call with a client in the opening scene.  He coworker expresses some concern and another coworker looks and rolls his eyes.  She meets with her boss and the conversation has overtones of sexual harassment.  Later there is a computer dating scenario where she ends up at her apartment with the date and starts to react like he is assaulting her.  She ends up taking some medication out of a medicine cabinet.  Later we see her Google "Support groups for stalking victims".  She drives out to a psychiatric facility for an initial appointment and that is where the drama begins.  I am going to list the problems point-by-point.

1.  She meets with the intake staff person and describes her concerns about being stalked as well as the residual "neurosis" (her term) of being in an new city and having a tendency to see her stalker everywhere. At one point she alludes to feeling depressed at times and thinking about whether there is any point in going on.  The staff person asks her if she has ever had suicidal ideation and she goes into a detailed discussion of Therapeutic Index and how she would be experimenting with that if she was going to attempt suicide (translation - overdosing).  The therapist leaves and has her complete routine paperwork.

2.  She completes the "routine paperwork" that is also described as "boilerplate" and learns that in doing so she has voluntarily committed herself for 24 hours.  In other words she was tricked into being hospitalized and that trick was apparently irreversible.

3.  While voicing strong objections she is asked by a nurse to disrobe, be searched, and change into hospital clothing.  The nurse's tone is threatening and she complies.

4.  She is taken to a psychiatric ward of about 10 people.  It is a combination of men and women and they are all locked into a room with no supervision all night long.  She is threatened by the other patients, gets into a physical confrontation with two of them and is eventually sedated in the same 10 bed ward in full view of the other patients with no safety monitoring.  She is subsequently restrained in the same manner in full view of all of the male and female patients and not protected.

5.  She finally sees the psychiatrist the next day.  He does the world's most cursory evaluation - largely reading chart notes in between phone calls.  It lasts about 5 minutes. She makes a compelling argument to be released. He informs her that she needs to stay another 7 days based on her assaults on another patient and staff. At no point in the interview does he ask her any direct questions about depression, suicidal thinking, or the details of the incidents of aggression.

6.  She befriends another patient who has smuggled in a cell phone and convinces him to let her use it.  We learn that the patient with the cell phone is really an undercover reporter investigating the hospital.  She calls her mother who comes to the facility and demands that they release Sawyer. The psychiatrist refers her to an administrator. The administrator gives her an irrelevant sales pitch on all of the good work that is done there and passive-aggressively acknowledges that it is her mother's prerogative to contact an attorney in order to get her daughter freed. 

From a creative and artistic standpoint - it was apparent to me from the outset that Sawyer's reality testing was not impaired.  Hypervigilance is not psychosis. So when she recognized her stalker on the nursing staff passing out medications it was not a surprise.

Spoiler alert right here - if you really wanted to be surprised see another film.  If you don't want to know the ending to this predictable one stop reading right here.

A series of implausible scenes unfold that depend both on the stalker as nursing staff and Sawyer's transformation to homicidality bent on killing the stalker/staff person. The stalker gives Sawyer a "megadose" of methylphenidate a stimulant a - controlled substance. Special effects at that moment seem to indicate she has some kind of psychedelic experience from the drug.  The stalker is warned by the nurse that he has to be more cautious of "we could lose our jobs." The stalker ends up killing two patients and torturing one of them with cardioversion paddles - right out of the old action series 24.  Some reviews of the film think this was an electroconvulsive therapy device - more proof that old Hollywood stereotypes about psychiatry don't ever go away.

The stalker traps Sawyer in an isolated seclusion room and in an excruciatingly long exchange, she tricks him and ends up stabbing him in the neck.  Like most films of this genre, he survives and recaptures her outside of the hospital and kidnaps her.  During the kidnap sequence we learn that he killed her mother and the hospital staff person who he has been impersonating.  Sawyer gets another chance to kill him and apparently does in the most gruesome manner  possible.

We flash forward 6 months and see Sawyer eating at a restaurant with a friend.  She looks out into the room and see the profile of a man who appears to be the stalker. She hears him saying things the stalker would say.  She grabs a steak knife and approaches him from behind.............. 

All of the points above are what a psychiatrist would consider to be highly problematic.  By that I mean they would all merit investigation by the appropriate authorities,  legal penalties, and disciplinary action against licensed health professionals. If I was prone to discuss malpractice - the incidents could also lead to that type of civil litigation.  Anyone experiencing a fraction of what Sawyer experienced in this psychiatric hospital should contact the responsible officials or an attorney about what could be done.  In my experience health officials are quite eager to do exhaustive investigations of these complaints both in the case of licensed health care professionals and institutions.  In the film it took a dead body on the premises to get any action from the police.  In real life, a call from Sawyer's mother would be enough to get action in any state that I have practiced in.

The commitment law in Pennsylvania did not seem to be adequately portrayed.  The statute says that any interested party can initiate commitment based on an imminent dangerousness standard.  That was certainly not present in the film.  At no point was Sawyer suicidal and the brief scraps that she was in would not have required physical restraint or forced medication in any setting that I ever worked in.  The maximum period of confinement in the state of Pennsylvania without a court order is 5 days and in this case Sawyer was detained 1 day initially and then another week.  That is a violation of the law.  In the state where I work, the longest period of time that a person can be help without a court order signed by a judge is 72 hours. In cases where it appeared a high risk person would be released, attorneys have always advised me that the person needs to be released according to the law - no matter what the possible adverse outcome.   

There are some continuity problems with the film.  How is it that her stalker would happen to know that she would be inappropriately admitted to a psychiatric hospital and be able to identify and kill a prospective employee in order to work there?  Wouldn't it be much easier to get close to her in real life rather than inside an institution?  And what about Sawyer?  She has insight into the fact that she is hypervigilant and needs to avoid the stalker. Is there a better film just exploring that theme and what happens to people in these situations plus or minus the real stalker?

In the past, my standard for films has been recognizing that they are entertainment and not really about psychiatry.  This film fails at both levels.  I suppose at some point all actors might be interested in doing a horror movie - but the psychiatric hospital as horror genre is as tiresome as it gets.  How many times can you show a gun toting Dr. Sam Loomis battling evil incarnate as a former asylum patient?   How many times can you show hospital staff that are sadistic, abusive, or grossly incompetent? Apparently there is no limit. The idea that a film like this should just be brushed off as fiction minimizes the fact that One Flew Over the Cuckoo's Nest seems to have stigmatized the most effective treatment in psychiatry for two generations.

The psychiatric hospital that Soderberg is reaching for is the spooky old asylum of the late 19th and early 20th century.  What made that asylum spooky was that people were freaked out about severe mental illness.  They did not know what it was and they did not have a name for the symptoms or disorders. They knew that some of their relatives went to these places and never came back. They lived the rest of their lives there.  They were warehoused and never got better.  That was the real scary part.  Most if not all of those places are shut down and have been for a long time.

The real horror story these days is trying to get into a mental hospital when it is needed.  Contrary to Sawyer's experience in the film, nobody is trying to recruit people into hospitals.  They are rationing the beds and turning people away.  All of the beds are typically full.  The emergency department psychiatric staff will do whatever they can to discharge.  A lot of people end up waiting a day or two and just give up and go home.  In some cases if people with mental problems are brought in by the police, the choice is admission to the hospital or jail.  Jail is the most likely outcome.

Jail is the real scary place these days and it has been for at least 20 years.  That is where a diverted patient needs to worry about incompetent or nonexistent treatment, physical assaults, and encounters with the evil people that Hollywood typically, uses to populate psychiatric hospitals.

The real evil out there today - is the system of non care that exists.  That is what people feared - developing a mental illness for which there was no treatment and being sent away for a lifetime. 

That is what Hollywood needs to understand.

That and a ton about modern psychiatric treatment.

The NEJM "Addiction As Learning And Not Disease" Article - Clinical Realities

I had anticipated posting a piece on the biological realities that were minimized in this review but I am currently waiting for a graphic that I acquired permission to use.  I have not heard back from the publisher.  In the interim, I will post some information on the clinical reality of treating people with severe substance use disorders or addictions to illustrate why learning is really an inferior paradigm to use in analyzing the problem.   It really comes down to treating all of the features of a profound loss of normal functioning.  These features are not subtle and include insomnia, anxiety, depression, cravings, compulsive use, and protracted withdrawal.  The following comments considers only those people with addiction that is defined as DSM-5 severe substance use disorder and compulsive use of any addictive substance.  By definition that means I am not considering people with less severe problems, such as the average college drinker or cannabis smoker who lacks these features, can easily stop, and invariably stops when they move on with their life after college.  I could post a series of vignettes but for brevity - I can roll all of those problems into one problem, that is generally recognized as the most significant drug problem in American today and that is opioid use disorder.

Consider the following hypothetical and all of the potential solutions and the implications for addiction as a disease or a learning opportunity.

40 year old man with chronic back pain, benzodiazepine use disorder and opioid use disorder.  Prior to admission he was using 10-16 mg clonazepam per day and 240-300 mg of oxycodone per day for 5 years.  The use disorder developed as a direct result of prescriptions of oxycodone 10 mg TID for back pain and clonazepam 0.5 mg TID for back spasm.  The patient was admitted to a residential treatment facility and detoxified with buprenorphine and phenobarbital over a period of 10 days.  On day 15 he is referred for assessment of depression and anxiety.  

He has no history of insomnia, depression, or anxiety prior to the onset of the substance use problems. Since the detox was completed (on day 10) - his anxiety is "through the roof", he is unable to sleep, and he is depressed and somewhat hopeless.  His concentration and focus are so impaired at this point that he can't retain information presented in groups or individual discussion and he feels like treatment is a "waste of money" because he has not learned anything.  He is craving benzodiazepines but also opioids to some extent.  He has drenching night sweats and has to change his shirt 2 or 3 times a night.  He describes muscle and joint pain.  He is concerned that he will relapse immediately upon discharge due to all of these symptoms.  He asks about taking trazodone for sleep, an antidepressant for depression, and gabapentin for anxiety.  He suggests that if the problem cannot be solved - he will go back to his primary care MD and get another prescription for benzodiazepines and that he will "try to control it this time."  

At this point the best intervention (s) to address these symptoms include (choose as many as you like):

a)  Continued 12-step facilitation groups
b)  Cognitive behavior therapy for insomnia (CBTi)
c)  Cognitive behavior therapy for substance use, anxiety and depression.
d)  A family program to educate the patient and his family about the relevant dynamics
e)  An NA group to deal with cravings
f)  Prescribe trazodone for sleep
g)  Prescribe an SSRI for anxiety and depression
h)  Prescribe gabapentin for anxiety
i)  Prescribe a benzodiazepine for anxiety
j)   Prescribe buprenorphine/naloxone (BUP/NAL) for opioid withdrawal and medication assisted treatment (MAT) of opioid use disorder.

Numerous learning and medical interventions for the problem and I have seen several to most of them applied in this scenario.  I have seen many applied repeatedly well past the point of failure to the point that a person may be leaving treatment more symptomatic than they came in.  That is a significant failure because the patient leaving in that circumstance is highly vulnerable.  This scenario is highlighted generally ion the movement to make sure that persons with opioid use disorder are prescribed BUP/NAL and given naloxone intranasal or injection when they make the transition from treatment setting or secure environments where they have had no access to opioids like jails.  That emphasis is important because of the overdose risk with opioids but the risk for relapse to using any substance requiring treatment is very high and potentially leads to a fatal outcome.

The other clinical consideration of addiction as disease is that it is multidimensional.  As highlighted in this case - it is not a simple question of detox, stabilization and discharge.  Significant physical symptoms of illness, intoxication, and withdrawal can persist well beyond any expected period of detox.  Significant sleep problems can persist for years beyond the detox period.  Striking psychiatric symptoms are all part of the mix and physicians not suspecting these disorders can attempt to treat them as depression, dementia, bipolar disorder, anxiety disorders, panic attacks, and even attention deficit-hyperactivity disorder.  Some treatment literature talks about a vague syndrome of protracted withdrawal symptoms that is often used to described any unusual symptoms or perception during the recovery period.  Addiction is a modern day great imposter of psychiatric disorders.  Clinicians following people with all of these symptoms can discuss general guidelines with people about how long it takes various symptoms complexes to resolve before a psychiatric disorder should be considered.   In some cases the symptoms are of sufficient severity that they need to be treated acutely and the issue of disorder versus disorder cause by the substance needs to be worked out in the long term.

A long standing debate in the treatment of substance use disorders is the role of physicians and medical treatment.  Medicine has always had a role in detoxification especially when it comes to potentially life-threatening detox or detox that involves significant discomfort.  The epidemiology of addictive disorders and psychiatric disorders points to an obvious reason to try to treat both disorders at once and a place for psychiatric treatment. Medication assisted treatment to reduce relapse has been the most recent medical innovation.  All of these roles are consistent with a disease model that seeks to correct or address a loss of normal function in the human body or brain.

I am an advocate of psychosocial therapies not just in addiction, but in just about all areas of psychiatry.  Further I am an advocate of 12-step recovery because it is cost effective, it works, and it has the realistic long term goal of abstinence.  In addiction treatment, those therapies work best if a person is detoxified, cognitively intact, all of the associated comorbid symptoms are treated, and (where possible) craving and relapse potential are reduced as far as possible to break up the cycle of compulsive irrational substance use.

Given all of those considerations what is the correct answer to the question?  None of the verbal therapy or experiential (a though e) options work, but I have seen them applied even when the person was in significant distress and no progress was being made.  There are no known talk therapies that adequately treat intoxication, withdrawal, or many of the intermediate states associated with early recovery that in some cases extend for 1-3 years.  What about the symptomatic treatment of psychiatric symptoms?  Not the best options either.  In this case, I have seen patients on multiple antidepressant, anxiolytics, trazodone, atypical antipsychotics, and even stimulants for the symptoms described.  In many cases the associated medications led to additional morbidity.  So treating this multidimensional illness as a single or a collection of psychiatric disorders is also the wrong answer.

The correct answer in this case is  j) Prescribe buprenorphine/naloxone (BUP/NAL).  In practically every case like this that I have been involved with since the advent of BUP/NAL prescribing the anxiety, sleep disturbance, depression, and physical symptoms all resolve or at least the portion of the illness that is directly attributable to opioid use.  In this case the patient was also using a benzodiazepine with a long half life and may also need to address those symptoms.  Protracted withdrawal from benzodiazepines has been described since the late 1980s and the symptoms can also last for a long time.

The clinical approach to addictive disorders provides clear information on why addiction is a disease whether you happen to accept any of the models proposed by Volkow and Koob or not. At every step of the way in the above example, the underlying systems are described in either of the main addiction texts.  There is clearly a loss of normal functioning that does not respond to talk therapy or other learning interventions.  In fact, these interventions presented to a distressed person typically create more problems than solutions. Although it is possible to insert neurobiology into any medical or talking intervention these days, learning interventions for the above problems can be expected to have little to no effect on the major problems that this patient is experiencing.    

All of those problems at any stage of addiction are a loss of normal functioning or a disease state. With addiction the loss of normal functioning is not trivial. It is disabling, severe, and life threatening. Any quality treatment program should be able to address them and not depend solely on a learning environment to assist these patients.

Computational Aspects of the Human Brain

As part of my lectures on the neurobiology of addiction - I digress briefly to discuss the computational aspects of the brain.  A lot of that discussion is focused on on the above graphic showing that overlaps in capacity with a list of the world's ten fastest supercomputers.  At least that is the estimate of the AI Impacts group.  It is basically a computation based on edges and nodes. I include power estimates for a brain from existing hardware to the actual power estimate of the human brain that I would guess every physical chemistry student from my era had to contemplate at one time.  And then I try to stimulate some discussion of supercomputers versus the human brain and it generally falls flat.  My Socratic process goes something like this:

"OK so we know that humans can't really beat computers on straightforward calculations so what advantages do we have?"

"I will give you a hint - why do we all go thorough residency training? Why can't you learn your specialty by reading about it in a book?"

The first lesson is pattern matching.  The human brain is designed not only to match patterns but to be trained to match a lot of them.  Some research article suggest about 88,000, but when  you consider what has to be matched that has be very a very low estimate.  I quote references from 15-20 years ago and a course I used to teach on diagnostics and diagnostic decision making.  Ophthalmologists correctly diagnosing diabetic retinopathy at a much higher rate than nonspecialists.  Dermatologists diagnosing rashes faster and correctly classifying ambiguous rashes with greater precision than nonspecialists. If I am really on a roll I might digress to talk about Infection Disease rounds at the Milwaukee VA sometime during 1982.  I was the medical student on a team of residents and fellows doing a consult for possible subacute bacterial peritonitis.  As the attending listening to the presentation he was also looking at a rash on the patient's shin.  By the time we were done he had also diagnosed a strep infection in addition to the peritonitis.  When you have significant pattern matching capacity, and you have been exposed to relevant patterns you can recognize them quickly and improve the speed and accuracy of the diagnosis.

I move on at that point to illustrate that the computers are catching up.  The simple captcha is less robust in discriminating machines from humans.  Opening an account may take more that checking the "I am not a computer" box. Now you might have to look at 8 pictures and check the one that contains an automobile or a stop sign.  Some of these photos are often difficult for humans to decipher.

At that point I touch on human consciousness - both the unique aspects and computational power it takes to generate.   About a decade ago I started saying that if there are 8 billion people on the planet - there are 8 billion unique conscious states. It makes sense at a number of levels especially when I put up hard numbers on cell types, protein types, the genetic information represented, and the typical stream of consciousness that every person experiences every day.  What is the content and flow of that activity? How does it get biased in psychiatric disorders and addictions?  How much computational power does it take to generate all of this information?

My latest step is what I like to consider The Matrix observation.  If I am standing in front of a room of 15-20 residents - what does it take to generate the physical representation of all of the people and all of the objects in that room? What does it take to make all of those representations unique? There can be a general consensus about what is happening - but just looking around it is clear that there are obvious different experiences.  One person looks very interested and one semi-interested.  One person is more focused on her Smartphone and is indifferent to my presentation.  Some people look sleepy.  Others look irritated.    They also appear to be indifferent to the context.  I know that my job is to try to get this information across and make is semi-interesting.  There is no real expectation on the residents.  It is clear from the questions I ask that they really don't know too much about the brain.  There are parallel streams of information processing that allow us all to evaluate what is occurring on the fly both the information content and emotion.  In some case there are pre-existing heuristics and in other cases associative memories and biases.  All of this represents a tremendous amount of information or computational power depending on how you may want to discuss it.

I have been preoccupied myself with the computational power and estimating it accurately. I used to try to model it in terms of electrical buses and neuronal firing rates - but the numbers I got were far too low.  There really are no good equivalents in the physical world with the possible exception of the Transversed Edges per Second (TEPS) metric used by the AI Impacts group for the above graphic.  You can't really use estimates of typical audio or visual information and concluding that is what is being processed by the brain.  I have never really seen an accurate estimate of all of the sensory information that the brain is handling in real time.

I went to bed last night and waited for sleep reverie or that period of time where you stream of thinking is jumbled and illogical just before you fall asleep.  As a chronic insomniac it is one of the few reliable cues that I am probably getting some sleep.  It happened when I had a sudden image of a baby high up on a brick wall, followed immediately by a person who seemed to be me sitting in a single seat futuristic car.  The salesperson was describing it to me and suddenly the car and everything else was being swept down what appeared to be a very sophisticated hydraulic roadway. The roadway was bright orange and the salesman shifted his pitch to tell me the advantages of this kind of a roadway with this car.  The roadway was moving at about 20 miles per hour.

I shifted briefly and remembered it was 2018 and I was in my bedroom in Minnesota.

And for a minute I thought about being able to estimate the information necessary to generate that brief full color science fiction scene and the three or four more I would encounter that night.

Some additional examples as they happened:


1. Dream of 11/22/2018:  I am back on my old inpatient unit.  The layout is exactly the way it was 20 years ago (the building has since been razed).  I am working with the same staff.  I walk into the examination room to look at the templates for the day.  In those pre-EHR days I had designed a template with all of the relevant features necessary for the billing and coding requirements.  At the time we were all threatened with legal action if we did not comply with these regulations even though they were totally subjective.  In those days I worked with a physicians assistant who prepared the templates ahead of time before we started interviewing patients and completing the subjective aspects of the evaluation and documenting the progress.

The templates were all stacked in two circular patterns - ten templates in each circle.  They appeared to be the exact temples that we used right down to the blurred fonts from being photocopied too many times.  The precise handwriting of my physicians assistant in the diagnostic section was exactly the way he wrote things down.  The placement of the exam table and crash cart were exactly where they were in reality.  The table we used was circular and about 6 feet in diameter with a laminated blonde wood finish and it was also exactly the way it was in that now 20 year old reality.

I looked at the templates and asked myself: "Why are they all face down?  I can't see the patient's name or identifying data.  I will have to go through them all to find the correct template when I start interviewing patients."

I felt somewhat irritated.

And then I woke up. 

2. Dream of 11/23/2018: I am in a large modern, multi-floor medical facility. It is not one that I specifically recognize, but it seem like there are elements of many that I have been in.  I am rushing around on the ground floor. The impression I have is that I am late for a lecture. It doesn't seem to be an explicit CME lecture but everyone else there (including myself) is too old to be a medical student or resident. I run into the elevator just beating the door as it closes.

I make to to the lecture.  It is basically a large room - maybe 50' x 50' and for some reason I burst through the door running at full speed.  Just before the crash into the back wall, a guy standing on the side wall grabs my arm to slow me down and stop me.

I ask myself if that was really necessary because my plan was just to stop myself by reaching out and planting my hand on the back wall.  I notice that there are several people who I assume are physicians that are standing and sitting near the back wall and they seem a little alarmed about something.

Then I am back in the elevator and headed to the ground floor.  I am walking out of the building and realize that I am chewing something metallic.  I realize that is is a collection of machine screws, nuts, and ball bearings. I realize that is purchased them on the ground floor of this building and that they are sold for that purpose.  I also know that I cannot really chew them or I will break my teeth.  I have to cautiously move them around in my mouth.  They remind me of a chap stick product that is applied with a ball bearing device at the end of the dispenser.

I wake up with a metallic taste in my mouth.

3.  Dream of 11/24/2018:  I am back in my home town. The streets and buildings are identical to the way they look in reality.  I am with a friend of mine and we are looking at a 1960s vintage Buick.  It is large and chalky white.  He tells me that his sister recently bought it and she wants to take everyone for a ride.  He thinks I should come along, but just then I remember something that his sister said to me in the last 15 years that would make me not want to go with them. He is talking about the car as though it is a great buy, but as I walk past the tail end of the vehicle, I notice that it has a new paint job and that whoever did it just painted over the decals of the previous dealers.  You can see them faintly through the paint.

I tell my friend that I can't stay around because I have to go grocery shopping. Just then one of his friends comes out and tells me that he has a lot of groceries he can just give me so that I will not have to go to the store.  I decline but he continues to insist. I reluctantly accept free groceries and sling them over my shoulder in a large garbage bag and start to walk home.

The real path home is just 6 blocks - 4 blocks south and 2 blocks east. It is all residential. But in the dream I encounter a large modern baseball park right next to the street. The game is just completed and they are interviewing the winning pitcher. She is in her mid 20s and short and compactly built.  Her uniform and short brown hair are drenched with sweat.  Just then I notice that it is hot. The announcer asks her if the heat was a factor in the game and she says:

"The hot was so hot that when my hot fingers touched the hot ball - I could barely feel it." 

The ballpark looks real.  There are thousands of cheering fans and the announcer and the pitchers statements are amplified over the PA system.  Everything is in color.

I wake up and feel hot and flushed.

The NEJM "Addiction As Learning And Not Disease" Article

The latest installment of what appears to be an endless debate about whether addiction is a disease or not hit this weeks New England Journal of Medicine in an article entitled "Brain Change in Addiction as Learning and Not Disease." I have looked at a few of the previous articles along the same line that purport to show why addiction is not a disease and it is fairly easy to show that disease or not a disease generally depends on the author's definition and pointing out why the other definitions do not seem to fit. It is basically an exercise in rhetoric.  Those approaches invariably end up at quite a distance from opinion polls that illustrate that most of the public and even more medical professionals consider addiction and severe mental illnesses to be diseases.  I will come back to the philosophical underpinnings of those polls at the end of this article.

In this case the author is essentially making three arguments.  Two of the arguments are in side panel graphics and the third argument is in the main text.  The first side panel argument (p. 1552) concerns the Brain Disease Model and Stigma. In it the points out that the disease model can be destigmatizing but it also can be stigmatizing to some people.  Although I do not agree with some of his premises let us accept that his argument is basically a wash and the people who feel stigmatized and recoil from the prospect of the addiction illness perfectly cancel out those that accept the model are are consoled by it. I recognize that a substantial part of the recovery community base their recovery work on the disease concept of addiction although it is not strictly similar to the biomedical disease that is typically described.  This entire panel described a sociocultural model of disease (2).  This concept is basically that different societies and the physicians in that society may have diverse views of diseases that vary from other cultures.  A secondary factor is that medical recognition may change how that disease has come to be viewed by the society at large.  For example, an illness that was once thought be be caused by moral deficiency is seen differently after it is recognized as a process that may be beyond the control of the afflicted person.  Mental illness, alcoholism, and addiction are common examples.  An associated feature of this model is that this concept cannot be used by the medical field that must concentrate on understanding the biological mechanisms that underlie the disease.  That makes this panel irrelevant to a medical disease concept.

The second side panel (p 1553) looks at Learning Models and Empowerment.  It can also be understood as a sociocultural model.  In this panel the author develops a number of arguments to suggest that if people were free of thinking they had a disease they would be more prone to self examination and less dependent on professionals and the need to adhere to what professionals tell them.  He suggests that disease mechanisms would lead to pessimism on the part of the person with the problem that would not exist if they were engaged in any number of learning programs to help them recover.  He uses the familiar quote that most people recover spontaneously without any help from professionals.  This argument depends on a couple of premises that are clearly flawed.  The first is the group that is described as having an addiction.  The convention I use for that is Volkow's definition of being equivalent to severe DSM-5 substance use disorder in any category.  That category has a high level or mortality, comorbidity, and chronicity. In this case the author seems to minimize the interventions used by addiction professionals to "making life-style choices to improve their prognosis."  That minimization serves his purpose to suggest that learning is an entirely novel approach to addiction when it has been used for decades.  Spontaneous recovery is an often quoted argument against a disease model, when it happens all the time in other conditions (obesity, metabolic syndrome, diabetes mellitus Type II, hypertension).  The fact is, spontaneous recovery by any number of conscious interventions does not preclude a disease process.

The bulk of the author's argument in the main text is based on illustrating how learning in addiction and normal learning are similar if not identical processes and therefore disease is a learning problem rather than a disease.  The most logical way to analyze this argument is to examine the conclusions first.  Looking at the conclusion highlights the seriously flawed premises in the author's argument that addiction is not a disease but is just learning.  I did not see any qualifiers that addiction is a special case of learning or not.

The author's believes that he has developed a "balanced model of addiction" that incorporates various learning mechanisms into what he calls and "embodied cognition model" of addiction.  In this model he sees baseline and adaptive biology interacting with the environment to produce the addiction.  It is interesting that the key environmental feature of drug use disorders - exposure to the drug is way down his list of other social, cultural and familial factors.  Some of his examples illustrate this point.

He discusses the socially disadvantaged youth raised in an adverse environment: "These persons tend to find increased meaning in drugs that reduce stress or promote feelings of security and well being especially because these effects can be attained without medication by other people." That does not explain the flood of advantaged white middle class youths who became addicted to heroin and represent a substantial number of overdose deaths.  It also does not explain the difference between two inner city youths who have to walk past 3 drug dealers on their way to school each day and one of them becomes addicted and the other does not.  One of the important lessons of the current  opioid epidemic should be that exposure to a highly addicting drug in biologically predisposed people is one of the central mechanisms of addiction.     

The authors "addiction spiral" is also problematic.  It begins with "early adversity and trauma" as the first step effectively limiting any explanatory power to that population. In step 2, he discusses development changes in the autonomic nervous system that may occur in response to childhood trauma that can lead to hypercortisolemia as an adult. That makes this model appropriate only for adults who have been traumatized as children and even then - only those children with this pathophysiology.  There can be a broad range of factors that lead to behavioral inhibition and anxious temperament (3). In step 3, he discusses early childhood adversity as a cause of epigenetic changes that can predispose to addiction.  He omits the concept that exposure to compounds like nicotine and other addictive substances are much more potent causes of an array of epigenetic changes and correlate highly with addiction. Kandel and Kandel (4) among others have shown that DNA hyperacetylation from nicotine is associated with cocaine use.  Epigenetic changes from drugs of abuse are widespread .  A recent study of the impact of smoking on the human genome concluded that as many as one third of genes in the human genome can be affected (5) by methylation of 18,760 statistically significant cytosine-phosphate-guanine sites. In order to claim a more potent learning effect at least an equivalent neurobiology of learning with equivalent impact that it applies across the entire population of people with addictions should be presented.  I don't think this paper reaches that threshold.   

That brings me to the point of whether it is relevant to use the disease concept at all.  I am sure that students have heard me say from time to time that it is not. That statement is usually accompanied by the statement that it still has to be recognized as a severe problem that is a significant cause of mortality and morbidity.  There is a little used philosophical approach to the disease concept that I have rarely heard about outside of reference 2.  That concept is disease as a departure from normal functioning (p 160).  In this discussion the authors develop the concept that organisms are a special case of programmed systems.  Normal homeostasis in humans is a result of that programming.  Biomedical research is focused on being able to discover that program and how it is coded, uncoded, and expressed as disease.  One of the authors' conclusions is:

"There is reason to believe that as research progresses, more and more biological processes at all levels of organization will come to be understood as programmed processes."

They refer to closed programming that are those resulting from direct decoding of the genome with inborn errors of metabolism being a key example.  Other phenomenon require an interaction with the environment to result in the full development of the programmed process.  They go on to suggest the existence of "open" programming where some form of learning or conditioning is required to complete the process.  Some of the programs may be "closed" at a certain point and not amenable to further decoding.  All of these programs are shaped by the evolutionary process.  Viewing organisms as biologically programmed systems (p 163) takes social values and norms out of the equation and provides a definition of normal functioning and it also defines the acceptable evidence necessary to delineate abnormal functioning.  The authors' straightforward definition of disease is given below:

"Disease is a failure of normal functioning."

Consider the following vignettes to illustrate that definition. None of the subjects noted had any adverse childhood experiences or pre-existing psychiatric disorders.  They all had positive family histories of addiction.

Patient 1: 22 year old woman who received hydrocodone after her wisdom teeth were removed at age 20.  She received a 14 day prescription and continued to take it even when her pain was gone.  At this point she started to acquire opioids from nonmedical sources and eventually switched to heroin for economic reasons and was injecting herself 4-6 times per day.  She went to treatment and was placed on buprenorphine-naloxone 16 mg/day.  On that dose she had no cravings for opioids and no withdrawal symptoms.  Her family has decided to withdrawal support based on considerable expenditures for various therapies that have been ineffective. She goes to a sober house but after a week there learns that there are fentanyl based products available.  She leaves the sober house in search of these products.

Patient 2:  45 year old man who is an IT professional.  His father and grandfather were alcoholics.  His grandfather died of cirrhosis. He decided at an early age that he needed to avoid alcohol in order to avoid alcoholism and did well with that strategy until about age 40.  At that point professional pressures to socialize with clients lead to some drinking that he escalated at home.  He can work from home and his drinking escalated significantly to the point he was drinking a liter a day of vodka that he consumed between 7PM and midnight.  This pattern continued for several years until he started to get episodes of alcoholic pancreatitis that required longer and more complex hospitalizations. He tried to stop drinking on his own.  He tried online courses that used cognitive behavioral therapy.  He went to Rational Recovery and eventually AA. Nothing worked and he knew that every episode of pancreatitis at this point was life threatening.       

Patient 3: 30 year old carpenter with no previous history of substance use. He was working in a new construction area and found one of his coworkers inhaling paint out of a plastic bag.  He tried it and experienced an intense episode of euphoria.  That night he went home and found Internet sites where solvent-inhalant users compare their experiences and give tips on usage. He picked up a popular computer duster product and was soon inhaling many cans a day. He eventually crashed his truck while inhaling the solvents and as the police pulled him out of the vehicle - he was still inhaling the solvent. When he was seen in the emergency department he told the physician there that he could not stop using inhalants because: "It felt like pure dopamine was coursing through my veins!"

The previous examples are not extreme cases in addiction medicine and addiction psychiatry. They illustrate a failure of normal functioning by compulsive use of a substance despite knowing that this use is irrational and repeated failures to stop.  One of the common comments about the majority of people with addiction stopping on their own totally ignores the people being seen in addiction settings.  It is this combination of severity, inability to stop despite severe consequences, and chronicity that leads physicians and lay persons alike to consider addiction as a disease.

What about the evidence of failure?  It can come in various forms.  In a standard medical format there is a signature clinical course or phenomenology of the illness.  Symptoms can be obvious in a physical or mental status exam. Laboratory testing including chemical and microbiological analyses, electrophysiological studies, imaging studies of various regions and tissues can be undertaken.  In all of these determinations the evidence can always be equivocal, false positive, false negative, or truly positive.  It often takes a level of expertise to interpret the evidence and a good example is electrocardiography.   

From a philosophical standpoint the authors in reference 2 point out the initial value of a functional-failure model of disease.  It has obvious implications for basic science research of disease mechanisms.  That research should be focused on discovering the programming errors in the human organism that results in failure of normal functioning with the hope of understanding the underlying pathophysiology and correcting it.  The model clarifies a role for statistics in the disease model specifically the strength of association of certain variables with normal and abnormal functioning as well as ways to analyze tests for those variables.  And finally, the concept makes it very clear that the disease in question is real and exists independently of societal biases.  I don't think for example that any of the above vignettes could be considered anything less than a failure of normal functioning. In the people addiction specialists treat, there is generally a trajectory of progressive isolation, multiple psychosocial losses, loss of relationships, poverty associated with addiction, and in too many cases - premature death due to the direct or indirect results of addiction.

That is the reality and it is captured by disease as a loss of normal functioning.

I am going to bring this post to a close at this point, but look for a more extensive look at the specific types of learning listed in this article compared with the biological impact on plasticity when people are exposed to addictive drugs.  I started out thinking that I was just going to continue my opinion about the disease concept being irrelevant but instead find that I have been invigorated by a view from a book I read over 20 years ago that is still relevant today.  I will end with a communication I received from one of the authors that I hope sums up this post and illustrates why physicians should probably not cloud the disease concept with popular notions like stigma or  empowerment:

"Most people would think epistemology is always irrelevant to ordinary life, but clearly it isn’t."

My thanks to both Ron Munson and Mike Resnik two of the authors of Reasoning in Medicine - reference 2 above.  Further thanks for Ron Munson for the quote at the end of this post and encouragement to explore his ideas about the disease concept.  It means a lot to hear from both of these authors at a point when they could have easily ignored me.  It is a sign that there are many kind and thoughtful scholars out there. 

As I type this at 2AM that thought about scholars gives me a warm feeling.

What Do Surgeons and Psychiatrists Have In Common? - Dread

I have had two surgeries this summer that have really impacted my work and daily life.  I only consent to surgery if it is a problem severe enough that I can't function or will kill me and the first one was for that.  I found a highly skilled surgeon who had done more of the procedures than occur in most countries in the world.  The procedure itself seemed to go surprisingly well. He gave me a prescription for oxycodone but the only treatment I needed for post op pain was acetaminophen.

I went in to see him a month later and everything was still going very well. No surgical complications and the target symptoms were in good remission. I did well for another 2 weeks and then got symptomatic again.  I was reexamined and the original surgery had scarred over requiring a second surgery to remove the scar tissue. He explained that is was very rare in his practice for that to happen, but that he did need to fix is as soon as possible.  The second surgery as done and I was functioning as good as new again.  He advised me to come back in 6 months for follow up.

There were post operative complications.  Despite antibiotic prophylaxis given during surgery I developed an infection with a fever and tachycardia.  He prescribed antibiotics but it got worse. I eventually went into the emergency department at midnight and was given intravenous Rocephin and told to continue the oral antibiotics until they were gone.  The infection cleared up in about 5 days.

I did very well and then at the 6 week mark again, I got progressively symptomatic and called the surgeon again:

Me:  "The symptoms are back, at about the same time frame and course of onset as they were in the past. Do I need surgery again?"

Surgeon: "Well probably.  It is highly unusual that it happened the first time and even more unusual if this has happened again.  I will just schedule the OR so we can take care of it early next week.  Can you do it then."

Me: "Well yes - I will do whatever I need to do to take care of this problem. I can't really go on like this."

Surgeon:  "I was just talking with my partner here and we need to alter the procedure to really remove more tissue when we take out the scar tissue this time. We really need to open that area up"

He sounded a little shaken. He is a top surgeon in his field and this is not just one complication but a second complication of the same initial surgery.  He was consulting his colleague and in this group all of the surgeons are very experienced and highly regarded. I wondered if he was concerned about what I was thinking?  He was safe there - even though it is practically an American standard to blame surgeons for sub-optimal outcomes that was never going to happen. I have seen surgeons with less skill than others and I picked him because of his record. There was no way that I was not going to let him do his job or suggest that I was in any way dissatisfied with his work.

I started to think about all of my years in acute care and how common it was to walk in the door in the morning and get blamed for everything by people who I have never seen before.  People who were there because they were in an alcohol or drug induced state and ended up under my care because there were unsafe and needed to be detoxified and in some cases treated for the psychiatric complications of substance use. People who were admitted for severe psychiatric disorders and associated aggressive or suicidal behavior.  Once they learned I was their psychiatrist - it was my fault that they were there - even though it was my job to get them out of there as soon as possible. My failure to do that resulted in a second tier of blame.  This time by hospital administrators who were often quite aggressive in encouraging me to get patients out of the hospital whether I though they were stable or not.  Shortly before I left the job, one of them actually told me that if I did not get the patient out - he would come down and discharge the patient himself.

I smiled to myself at that point and realized it was a very good thing that I was not blaming my surgeon for anything.

And then I thought about being in the same situation. Most people who have not practiced in acute care have not seen some of the problems that have no solutions.  Aggressive behavior that does not respond to medications.  Catatonic behavior that rapidly leads to life threatening dehydration or starvation.  Bipolar patients on dialysis who are delirious for months waiting for kidney transplants.  Patients with multiple medical complications who are agitated and can't sleep.  On some days an endless list of problems that would keep me up all night long trying to figure out solutions.  I would call and email one of three colleagues who I knew I could count on. They had been working acute care as long as me and I always appreciate their input. We only consulted one another in situations where we had no obvious solutions and we also had a sense of dread. Dread in the sense that you start to ask yourself: "Is there really no solution here? What am I missing? Have I lost it? Do I need to take a break and work somewhere else for awhile?"

There were a lot of nights where I would just lay in bed, thinking about the situation - sensing the blood pulsate throughout my body and feeling a light sweat on my skin. I would get out of bed in the morning amped up on adrenaline and feeling like I had slept for 8 hours when it was probably closer to 1 or 2.

Luckily in my case, there was resolution.  It could happen after a couple of sleepless nights. On many of those nights I would have contact with the nursing staff to see if any modifications could be done while I was away.  I would finally get a break and things would be all right for 2-4 weeks before another crisis hit. It would usually be a surprise. I walk into the unit in the morning and hear "Mr/Mrs Smith is up out of bed eating this morning.  They made a big turnaround last night."

Hoping for that break is the only thing that kept me going. You can only tell yourself that you have done everything right for so long. I never got to the point where I expected that break. It always struck me as very lonely and bleak. My senses seem dulled and everything slowed down around that problem. When the break happened - life was finally good again.

I was able to step back from these associations and realize that my surgeon was likely experiencing some of the dread I typically encountered in acute care.  Despite extended and best efforts - things are not going well and you don't really know why. There are no easy or apparent solutions.

Surgeon: "I should probably see you tomorrow before the surgery. I am sorry this happened. Can you be there are 7:30?"

Me: "Thanks. Yeah I can be there at 7:30.  See you then."

I was very calm and I slept well that night.

Biomedical or Biopsychosocial or Psychopharmacologist?

Elements of a psychiatric evaluation

Apparently these are desperate times for some professionals.  So desperate that they have nothing better to do than argue about proven psychiatric methods that include the clinical methods that includes data gathering and diagnosis. Some would prefer to move psychiatry away from the rest of medicine based on fallacious arguments that there are no clear connections between biology and clinical phenomenon and no apparent connection between psychiatry and the rest of medicine. These arguments are so extreme that they lack clinical utility and yet there is a small by vocal group of people who try to gain political favor with what is essential reworked antipsychiatry rhetoric. As a reminder I use that term as a philosophical definition that has been used to characterize the work of Szasz and Foucault. It is agnostic in terms of the proponents. In other words, as far as I can tell you don't need to be a cult member to be a proponent of antipsychiatry. You can be a psychiatrist like Szasz.

I posted a good example of this position a few years ago.  In the post I looked at a special interest group using medical model pejoratively and applying it to psychiatry.  I illustrated how the authors account of medical model on 2 1/2 of 3 dimensions that they were using as a basis for their argument.  The eventually develop a trauma based model of psychosis and state that is all that you need to know in terms of etiology and treatment. That is their refutation of the comprehensive psychiatric model for information gathering and analysis.

Another incredible critique of the field came from the journal Health Affairs and it suggested (like most critiques of the field) that the authors really had no knowledge of psychiatry or what psychiatrists do. Specifically they seemed to have no knowledge of the biopsychosocial model of psychiatry, specific psychiatric research in that field, and how all of that information is used in day to day psychiatric practice.

The obvious point that I am making here is that psychiatrists are trained and interested in multiple factors that may be important in both the etiology and treatment of psychiatric disorders.  That includes many biological factors like toxin exposure, endocrine conditions, infectious diseases, and brain injuries as well as more subtle biologically determined factors like temperament and developmental history.  It includes the status of interpersonal relationships and psychological factors. It includes the status of other organ systems in the body and chronic medical conditions.  There are specific posts on this blog about cardiac status, sleep apnea, cirrhosis and liver disease and pancreatitis. All of these illnesses and more are encountered in routine psychiatric practice.  Psychiatrists must in some cases make the diagnosis and in other case modify therapy to account for these illnesses and not provide treatment that is contraindicated.

That leads me to the figure at the top of the page.  All of the elements are contained in the assessment of the patient. It is not unique to psychiatry, and most physicians who directly assess patients have been using one form or another of it since they were first or second year medical students learning how to examine patients.  The main difference for psychiatrists from other physicians is the formulation section. This is not the list of diagnoses, but a synthesis of all of the data gathered during the interview process and at times from collateral sources.  Consider the following hypothetical example:

========================================================================

Formulation:

The patient is a 48 year old married woman with a history of insomnia and depression dating back to middle school.  She also had nightmares and night terrors during childhood but they resolved by the time she was in her late teens. Her current sleep problem is initial and intermittent insomnia.  She has been on various antidepressant medications about 90% of the time since she was 18 years old and has not found any of them to be very effective, but she does think that she gets some partial relief from fluoxetine.  She has been married for 18 years.  Her husband is supportive and they have a solid relationship.  The couple has 3 sons who are 10, 12, and 17 years old.  she had no episodes of postpartum depression.  She took fluoxetine during the last pregnancy.  There is a family history of depression in her mother and maternal grandmother. Her maternal grandmother was institutionalized and received electroconvulsive therapy.  Father and paternal grandfather had alcohol use problems. She is an electrical engineer and works in the tech industry in chip design.  She was previously active in a group that encouraged girls and young women to focus on STEM subjects in school and as a career choice but she has fallen away from that lately.  Over the past three years her alcohol consumption has increased from 2-3 standard drinks per day to 8-10 drinks per day. When she is drinking on  daily basis her mood is significantly more depressed.  During a recent episode of intoxication she sustained an intracerebral hemorrhage that was noted on an MRI scan of the brain in the left frontal cortex. She reports no cognitive or personality changes with that lesion but has had frequent headaches. She denies any history of abuse or psychological trauma, but said that her parents spent less time with her than her older brothers and that left her with a feeling of being less valued at times and questioning her self worth. She identifies strongly with her father who was also an engineer and encouraged her interest in math and science.

Diagnoses:

1.  Persistent depressive disorder
2.  Primary insomnia
3.  Intracerebral hemorrhage - assessed and treated by Neurosurgery trauma service. Serial scans show resolution with no evident abnormality.
4.  Headaches secondary to 3.

========================================================================

A typical medical surgical evaluation using the same general outline will not put all of the data together to explain the patients psychiatric diagnoses or symptomatology.  Medical or surgical evaluations typically end with a list of diagnoses that typically focus on an organ system or the brain idendependent of any psychiatric factors.  The diagnostic formulation is a psychiatric innovation that has utility as a way to study diverse etiologies of mental illnesses and in this case to try to understand the unique biological, social, and psychological variables for each person who is being treated.  It is in contrast to the diagnoses which are supposed to be atheoretical (but are not really) in the DSM. The formulation allows us to develop unique theories about what might be contributing to the person's distress.

I have been a longstanding critic of the lack of a psychiatric focus on the conscious state.  Only recently did I have the thought that this biopsychosocial (BPS) formulation is an approach to the study of a unique conscious state. The broadest definition of consciousness is experience.  If you develop a good technique and confirm the observations and theory about how all of the dimensions impact on them - it is basically a study of a unique conscious state.  An elaboration of the elements contained in either outline - would lead to a discussion of the person's experience of any number of life events including growing up in her family of origin, going to school, working, her leisure time experience, and her experiences as a wife and mother.  That is probably a very liberal interpretation of the BPS model.  Interested readers can find original papers written by George Engel in the references below.  The BPS model generally looks at multiple systems relevant to biological organisms and the philosophy of general systems theory.  The reader can get a good overview of Engel's theory by looking at the articles and the accompanying diagrams. Ghaemi has written an excellent book on BPS (6), it shortcomings and what he considers a more appropriate model for psychiatry - method-based psychiatry.  In his book he goes so far to outline how it can be taught to residents. 

The problem with all of the terminology is that I know very few psychiatrists who practice or prefer to practice in a restricted biomedical mode. A few examples that come to mind were some of the psychoanalysts who were my teachers 35 years ago who "prescribed a little amitriptyline for sleep." I suppose there may be some psychiatrists out there prescribing fluoxetine and not attending to their patients medical disorders - but happy to report that I don't know any.

That brings me back to the central point of this post. Do you really need to distinguish yourself as a biomedical or biopsychosocial psychiatrist if every other psychiatrist is doing what you do? Do you need to call yourself a psychopharmacologist?  Do you need to call yourself a medical psychiatrist?

I would say that you do not. Psychiatric training exposes trainees to the same content and clinical contexts where they an observe and treat severe problems. In many of those situations they are responsible for the total medical care of the patient.  They accumulate medical knowledge on a consistent basis as they accumulate knowledge about diagnosis and treating medical conditions. It is an inescapable part of the practice of medicine. Where do all of these titles come from?

I see a couple of origins.  The first is political and that is people who are using the terms in a pejorative way. There are apparently psychiatrists in the UK who use the term biomedical psychiatrist in a pejorative way because they don't believe in any diagnosis or they adhere to the old Szaszian concept of disease and do not want to see psychiatry practiced as a medical specialty. Many would go as far as not using diagnoses at all. They often equate diagnosis with the pejorative term labeling. When I think about that movement and its origins and how psychiatry got to where it currently is today - I ask myself about the development of both paths of thought. Without going into too much detail - there are no geniuses on the antipsychiatry path. Many of the early proponents on that path failed because they really had nothing to offer people with serious mental illnesses. If anyone wants to refer to me as a biomedical psychiatrist - I embrace it because it certainly does not deter me from doing  thorough psychiatric assessment that includes a formulation that contains social, cultural, and biological factors unique to the person I have assessed and trying to appreciate their conscious experience in each one of those domains.

The second application of the various descriptors is to differentiate oneself from the rest of the pack. That also seems to be a dubious distinction. The best example I can think of is psychopharmacologist.  If I have studied the subject, attended the seminars and courses, but spent most of my career discontinuing medications and treating complications in polypharmacy situations - am I psychopharmacologist?  Or do I need to be the person prescribing all of the polypharmacy? As far as I can tell - all psychiatrists are (or should be) psychopharmacologists.  They should also be aware of the limitation and be able to practice specificity in the prescription of psychiatric medications. 

 Psychiatrists are psychiatrists.  They are the same, but different like any other discipline.  Apart from what they know or should know their conscious state is certainly a factor in how they practice and there are always potential differences in skill levels.

I continue to be impressed by the high level of skill of my colleagues and think that we can all be psychiatrists and be confident that we don't have to be defined by anyone else.  Anyone who suggests that they have a better approach or that they can treat patients without a diagnosis should be confident enough to proceed and compete directly.  That said we do need to refine the technical skills in the field.  A primary consideration is realizing that we have come as far as we can go with the DSM approach.  Ghaemi's suggested methods based approach presents some good ideas on a philosophical basis - but the personalized medicine and omics approaches also hold a lot of promise.
