This war is interesting as in New Zealand ACC is trying to make a DSM diagnosis madatory for treatment.
Two eminent retired psychiatrists are warning that the revision process is fatally flawed. They say the new manual, to be known as DSM-V, will extend definitions of mental illnesses so broadly that tens of millions of people will be given unnecessary and risky drugs. Leaders of the American Psychiatric Association (APA), which publishes the manual, have shot back, accusing the pair of being motivated by their own financial interests – a charge they deny. The row is set to come to a head next month when the proposed changes will be published online. For a profession that exists to soothe human troubles, it’s incendiary stuff.
Psychiatry suffers in comparison with other areas of medicine, as diseases of the mind are on the whole less well understood than those of the body. We have, as yet, only glimpses into the fundamental causes of the common mental illnesses, and there are no biological tests to diagnose them. This means conditions such as depression, schizophrenia and personality disorders remain difficult to diagnose with precision. Doctors can only question people about their state of mind and observe their behaviour, classifying illness according to the most obvious symptoms.
