Psychiatric diagnoses: a continuing controversy.

Abstract

Psychiatric Medicine has been accused justly of making its diagnoses on the patient's report of symptoms and the physician's subjective observations of the patient. The main problem has been the lack of reliable data compounded by the stigma of a mental diagnosis. More recently, third-party pressures have become an added threat to objectivity. New knowledge of brain function, especially neurotransmitters, and more specific and effective medication have made the need for accurate diagnoses more acute. Psychiatry has responded by frequent and often controversial changes in its diagnostic criteria. Much of the controversy stems from a lack of accurate measurements to validate the diagnoses, thereby allowing for differences of opinion of a highly subjective nature. The problem is complicated by the chronic, but irrational, belief that there is a separation between mental and somatic illness.
