Intermittent Explosive Disorder
Scientists say that a rare form of mental illness could be the cause of road rage. A study from Harvard University says that as many as 16 million Americans could be suffering from Intermittent Explosive Disorder.
This report from Matt McGrath:
Intermittent Explosive disorder, or IED, is a condition in which people attack others, and their possessions, often causing bodily harm and property damage. The level of anger displayed is out of all proportion to the event that triggered it, so scientists believe it could be the root cause of road rage or even spousal abuse.
People with this disorder feel a sense of relief during the angry outburst, and then feel remorseful about their actions. It is these feelings of shame and embarrassment that have kept the condition relatively hidden, according to the researchers. The disorder affects twice as many men as women and the first outbursts usually take place in adolescence. The researchers believe that there is a strong genetic element to the condition, and growing up in a home where parents had difficulties with depression or alcohol was often a trigger.
IED often precedes depression, anxiety, alcohol and drug abuse. Over eighty per cent of those diagnosed with IED suffered from these conditions as well. The scientists behind the study say that anti-depressant medicine, combined with teaching people how to handle their feelings of frustration, can be an effective treatment for the disorder.
This research only applies to the United States, but further studies will take place in thirty countries to see if IED is truly a worldwide phenomenon.
