"Intermittent explosive disorder", is a psychiatric condition where victims have a very short fuse, are rash, impulsive, and hostile and could display outbursts of anger.
Scientists also found that those diagnosed with IED portrayed some markers of inflammation in the blood as compared to people who were cool and calm.
Also the level of one, C-reactive protein (CRP), was found to be twice as high in "explosive" individuals. Another marker, the signalling molecule interleukin-6 (IL-6) was especially present in people with the worst records of aggressive behaviour.
"These two markers consistently correlate with aggression and impulsivity but not with other psychiatric problems. We don't yet know if the inflammation triggers aggression or aggressive feelings set off inflammation, but it's a powerful indication that the two are biologically connected, and a damaging combination."
The research shows that anti-inflammatory drugs such as aspirin may help in calming people who suffer from IED.
"Medications that reduce inflammation may also drive down aggression," researchers said.
