...last week's conference, there were tantalizing hints that the DSM-V might fix some of these problems. Dr. Steven Hyman, provost of Harvard, a former psychiatry professor at its medical school and a former director of the National Institute of Mental Health, agitated at the meeting for a new DSM framework that would stop trying to divide mental problems into discrete all-or-nothing categories. That method is appropriate for some medical problems - you either have leukemia or you don't - but depression, for instance, doesn't work like that. (Read "Why Do the Mentally Ill Die Younger...
Rather, Hyman argued that many mental illnesses are problems that lie along a continuum from normal and functioning to disordered and tragic. To the annoyance of some old-fashioned DSM defenders, he made the case that the DSM should regard mental illness as "continuous with normal": less like leukemia and more like hypertension. You don't get diagnosed with hypertension until you meet a cutoff point for high blood pressure that takes into account other extenuating factors: your age, for instance, or the conditions under which the blood-pressure reading is taken. Depression should be the same...
Hyman noted that medical problems, whether in the mind or in the body or both, are usually caused by some combination of genes, environment, behavior and chance. Despite the comforting modern notion that severe psychological illnesses are simply due to an unfortunate genetic inheritance, it is the exceedingly rare mental condition that is caused only by genes. (Rett syndrome is one example.) Rather, if you take something like generalized anxiety disorder (300.02), there may be a variety of causes that set it off: genes that cause excessive activity in the fear-producing part of the brain called the amygdala...
Other attendees at the APPA conference indicated that the new DSM will almost certainly adopt a continuum model for mental illnesses. But don't be surprised if the book doesn't come out as scheduled in 2012. If the three-day conference came to any solid conclusion, it was that toting up all the ways our minds can fail is a lot harder than, say, explaining why your appendix might burst...
