@ Ilse, I think there are a number of different issues in your post. The "simpler" one being GP's etc. not refering patients who are obviously in psychological distress. Why don't they? -> some potential reasons: inability to accurately recognise psychological distress, emotional distress being judged as a "lesser problem", distrust/lack of knowledge of psychology, patients not actually presenting with emotional distress (or downplaying it) to GP's, and lastly the option opened by David, namely that medically trained persons probably have a bias towards seeing the physical (as an explanation for everything else) - just like psychologists probably have a bias to see the psychological/emotional/metaphysical.

The spilt between medicine/psychology+body/mind is, as David pointed out, complex. It should be kept in mind that medicine/psychology have a vested interest in the split but that psychology is perhaps a bit more vulnerable . . psychology may therefore be contributing to the split to a greater extent than medicine?

I try to avoid watching Oprah.  It gets too costly having to replace
the television set after I inevitably throw the nearest object at it,
halfway into the program.  Nevertheless, apparently she interviewed
Jill Bolte, a neuro scientist who suffered a stroke and has written
the book "My stroke of Insight".  I have only had the rare privilege
of a patient being able to articulate, in minute detail, her
experience of the actual event of the stroke.  Jill Bolte does so in
the following video http://www.ted.com/talks/jill_bolte_taylor_s_powerful_stroke_of_insight.html.
For a student of postmodern theory, working with clients post stroke
has been a useful reminder not to underestimate the medical/physical
reality to our mind body connection.
