One form of aggressive behavior with which psychiatrists are familiar is intermittent explosive disorder. It is characterized by recurrent episodes of aggression involving violence or destruction of property out of proportion to a provocation. Information about intermittent explosive disorder can be found in Psychiatric News.
Other recent research on aggression has found that a small protein called neuropeptide Y, which can be found in the hypothalamus and other brain regions, appears to play a key role in aggressive behavior. An antagonist of neuropeptide Y might be able to temper aggression in some individuals. Read more about this topic in Psychiatric News as well.
