Normality endangered: "Psychiatric fads and overdiagnosis"

That's the title of this week's Psychiatric Times commentary by Dr. Allen Frances, chair of the DSM-IV Task Force and psychiatry professor emeritus at Duke University. The column begins:

Fads in psychiatric diagnosis come and go and have been with us as long as there has been psychiatry…. In recent years the pace has picked up and false "epidemics" have come in bunches involving an ever-increasing proportion of the population. We are now in the midst of at least 3 such epidemics -- of autism, attention deficit, and childhood bipolar disorder. And unless it comes to its senses, DSM5 threatens to provoke several more (hypersexuality, binge eating, mixed anxiety depression, minor neurocognitive, and others).

Fads punctuate what has become a basic background of overdiagnosis. Normality is an endangered species. The NIMH estimates that, in any given year, 25 percent of the population (that’s almost 60 million people) has a diagnosable mental disorder. A prospective study found that, by age thirty-two, 50 percent of the general population had qualified for an anxiety disorder, 40 percent for depression, and 30 percent for alcohol abuse or dependence. Imagine what the rates will be like by the time these people hit fifty, or sixty-five, or eighty. In this brave new world of psychiatric overdiagnosis, will anyone get through life without a mental disorder?
While focusing on the alarming spread of psychiatric diagnoses among children, as he has in the past Dr. Frances touches on the forensic implications of diagnostic freneticism:
Mental disorder labels can provide cover for societal problems. Criminal behavior has been medicalized (eg, rape as a psychiatric disorder) because prison sentences are too short and such labeling allows for indefinite psychiatric commitment.
Frances concludes:
The DSM-5 bias to thrust open the diagnostic floodgates is supported only by flimsy evidence that does not come close to warranting its great risks of harmful unintended consequences. It is too bad that there is no advocacy group for normality that could effectively push back against all the forces aligned to expand the reach of mental disorders.
