Intermittent Explosive Disorder could be behind cases of road rage and spousal abuse; Early detection key to treatment

BOSTON--A seldom-studied mental illness called Intermittent Explosive Disorder, characterized by recurrent episodes of angry and potentially violent outbursts--seen in cases of road rage or spousal abuse--has been found to be much more common than previously thought. Depending upon how broadly it is defined, this disorder affects as many as 7.3 percent of adults, or 16 million Americans, in their lifetimes. In a year, Intermittent Explosive Disorder affects nearly 4 percent of Americans, or 8.6 million adults, reports Ronald Kessler, PhD, professor of health care policy at Harvard Medical School (HMS), and colleagues. The study also found that Intermittent Explosive Disorder may predispose people to other mental illnesses and substance abuse. These results are reported in the June 2006 issue of Archives of General Psychiatry.

Intermittent Explosive Disorder attacks are out of proportion to the social stressors triggering them and are not due to another mental disorder or the effects of drugs or alcohol, according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV). People with this disorder overreact to situations with uncontrollable rage, feel a sense of relief during the angry outburst, and then feel remorseful about their actions. [read more]
