I know nothing of the etiology or treatement of Intermittent Explosive Disorder. We all knmow a little more about its prevalence after the recent study Harvard Medical School survey on IED. Will we now see Road Rage, Wrap Rage, and other species of temper tantrum analyzed down to the genetic level?
Rather than travel too far down the neuro chemical route lt's look at environmental factors.
In spite of the stereotype of the "angry crip" it has always been surprising to me, observing the disability community from the inside for more than 300 years, how patient people with disabilities are.
So my suggestion for lowering the incidence of IED - even among those still temporarily not disabled - is Universal Design. Remove the obstacles. Decrease the frustration. Make human beings in all the "problem."
