Brain abnormalities could be the cause for teen aggression and anti social tendencies, states a new study.
The find could help government help sufferers and their families to cope with conduct disorder into adulthood.
"Detecting conduct disorder in adolescence may be too late to do anything about it. Early identification of a biological abnormality may be a route to take in terms of early intervention," The Independent quoted Andy Calder of the Medical Research Council's Cognition and Brain Sciences Unit in Cambridge, as saying.
"We looked at who has the least and who has the most severe symptoms and we see an increasing pattern of abnormality as the symptoms in the individuals get worse," Calder said.
"It could be due to being born with a particular dysfunction or it could be due to experience during life, such as a distressing experience early in life that could have an impact on the way the brain responds," he added.
The study is published in the journal Archives of General Psychiatry.
