The history of the DSM is not itself without
controversy. Although the details escape me at the moment, it is like any other
attempt to
define reality.
There are fashions in psychology, psychiatry, psychopathology, neuropharmapsychology, or whatever else is current. In recent years, medications have become the rage--such as for social anxiety. The division of the human psyche into smaller and smaller pathological bits should be met with some skepticism.
Instead of multiplying the human psyche by dividing it, we should, somehow, in whatever way we can, be putting it bach together again into whatever whole we can.
See psychiatrist.
