A Consciousness Based Model

One of the criticisms of psychiatric treatment in particular drug therapies is that essentially nothing is known about psychopathology, neurobiology, or human genetics and therefore claiming that drug therapy is treating a pathological state is erroneous (1). "Chemical imbalance" can be used as a red herring along the way and I will try to address that in a later post.  In that post, I also hope to address the issue of disease states and whether or not they need to be strictly measurable.

For now, I want to discuss a model that I have used in clinical practice for the past decade that addresses both the issues of recovery and whether or not the drug altered state or treating an underlying pathological state is really the issue.  Let me start by saying I think it is irrelevant for the purposes of treatment.  I am first and foremost a clinical psychiatrist and not a researcher and my priority is at all times patient care.   My goal is to treat alterations in a person’s conscious state and restore their level of functioning with medications and/or psychotherapy that have been shown to work.   My goal is also not to introduce any new problems such as sedation, mood changes, rage, perceptual problems, ataxia, false memories, vertigo, or any number of subjective changes commonly seen as "side effects".

I found that the best way to proceed is to have an explicit discussion of the person’s conscious state and whether it has undergone any transformation associated with the reasons why they are seeing me.  I focus on the typical stream of consciousness that occurs each and every day and how it may have changed over the previous weeks or months or years.   I ask about whether or not getting back to that conscious state is a reasonable goal.  I point out that the phenomenology associated with a person's cognitive and emotional changes (2) can be followed in at least two dimensions at once - the psychopathological and the normal.

There are obviously problems with my approach. The subjective assessment of a psychopathological state and the subjective assessment of the baseline conscious state are difficult to do and they take time.  There are a large number of markers of psychopathological states but not so many for normal conscious states.  I often end up discussing broad outlines that include the typical stream of consciousness, fantasies, daydreams, defense mechanisms, distracting thoughts and typical thought patterns in certain situations such as driving into work each day.   I also ask about a global assessment and whether at any point during treatment the person feels like their original conscious state has been restored.   It adds another goal to treatment that is focused on restoring the self rather than just treating symptoms.
