"If we can detect IED early and intervene with effective treatment right away, we can prevent a substantial amount of future violence perpetration and associated psychopathology," Ronald Kessler, senior author and McNeil family professor of health care policy at Harvard Medical School, said in a statement.

IED typically begins in late childhood and persists through a person's middle years.  In order to be diagnosed, a person must have multiple instances of uncontrollable anger attacks - "completely out of proportion with the precipitating event" - that have resulted in violence or damage to property, according to the Mayo Clinic.  The syndrome is often linked with the later onset of other debilitating conditions, such as depression and alcohol and drug abuse, Kessler said.

However, the study's findings also indicated that IED often goes under treated - with only 37.8 percent of youths with IED getting treatment for emotional problems the year before the study.  Only 6.5 percent of those with IED obtained treatment specifically targeting anger.
