Anger and Emotional Brain
     It has proved through neuro-imaging studies that frontal limbic regions of the brain regulate emotions. These emotions play a role in aggressive behavior. It’s also known that individuals who are diagnosed with intermittent explosive disorder (IED) have significantly less amount of grey matter in these specific regions of brains. DSM-V defines intermittent explosive disorder as recurrent behavioral outbursts representing failure to control aggressive impulses. These outbursts last for less than 30 minutes.

     Usually aggressive outbursts involve verbal aggression, damage or destruction of property and physical injury of animals or other individuals. Additionally a study, published in the journal Biological Psychiatry: Cognitive Neuroscience and Neuro-imaging. In this study researchers collected MRI scans from 168 subjects. Some of these subjects have IED and others didn’t have such disorder. Study also used 58 subjects as a control group to compare the differences. They found the positive correlation between subjects with a history of aggressive behavior and the level of reduction in grey matter volume.

     Aggressive outbursts are most common than bipolar disorder and schizophrenia. Scientific and lay communities believe that impulsive aggression is simply 'bad behavior' that requires an 'attitude adjustment.' Although, our data confirm that intermittent explosive disorder isn’t a disorder of personality but it is a brain disorder. Finally Dr. Cameron Carter of the University of California, who is editor of the journal said: "These important findings propose that disrupted development of the brain's emotion-regulating circuitry may underlie an individual's propensity for rage and aggression."
