NEW DELHI : The brains of people who show life-long pattern of anti-social behavior tend to be physically smaller than those who show such behavior only during adolescence, says a new long-term study led by an international team of neurologists. Out of total 672, 80 people showed life-course persistent anti-social behaviour (stealing, aggression and violence, bullying, lying, or repeated failure to take care of work or school responsibilities). While, 151 showed antisocial behaviour only during adolescence and 441 had low anti-social behaviour. Researchers found, that brains of individuals who continued to show life-long pattern of anti-social behaviour upto the age of 47 had a lower surface area and cortex which was substantially thinner, than the ones who did not show any such behaviour. Interestingly, these widespread differences were not seen in people who showed anti-social behaviour only as teenagers, but not as adults.
