http://www.medscape.com/viewarticle/873762 This is an interesting read - very popular and lots of comments. The author is very critical of the DSM... 'Psychiatry is the least medical of medical branches. Some celebrate this fact, others rue it; some deny it; many refuse to come to terms with it. It's acceptable in a way, if by "medicine" we mean biological aspects of physical diagnosis and treatment, because psychiatry deals sometimes with the mostly physical and sometimes with the mostly psychological. But psychiatry is medical, in the sense of dealing with diseases (whether mental health professionals want to admit this reality or not). The problem with that medical aspect of psychiatry is that the field is ambivalent about it. The diagnoses found in the Diagnostic and Statistical Manual of Mental Disorders(DSM) are created as social constructions, as preferences of the profession—not solely, or even primarily, as scientifically based definitions. For two decades, our profession has bound itself to these social constructions and pretended that they were scientific facts. This has been proven a lie, but we are unwilling to admit our self-deception.'
