"Recent studies have indicated that up to 75% of young offenders have some sort of cognitive deficit, including learning disability. In 1991/92, males represented 80-90% of the cases that came to the attention of the youth justice system. Boys with severe learning disabilities are more than twice as likely to engage in delinquent activities as boys not so affected. They are also more likely to be arrested. This does not mean that learning disabilities lead to delinquency, but rather that learning disabilities place a young person in an increased risk category."

"[Various] studies over a period of nearly 40 years... suggest a relative incidence of neuropathology among violent offenders many times in excess of that found in the general population, at ratios ranging from a high of 31:1 in the case of homicide offenders through 21:1 among `habitual aggressive' offenders to a low of 4:1 in the case of `one-time aggressives.' We propose that, though such discrepancies do not confirm neuropathology as univariately causative of criminal aggression, neither is it reasonable to believe that they are simple artifacts of chance."

Hennessy, presentation to the 35th

"Many neuroscientists now believe that one key factor in violent behavior is a failure of impulse control. In at least a subset of violent offenders, the inability to control certain drives and desires may lead to acts of violence and aggression. No one believes that a simple neurochemical produces antisocial behavior, but evidence from several laboratories indicates that the neurotransmitter serotonin is a key player in impulse control."
Nancy Touchette, in the Journal of
NIH Research, February 1994

"New insights about the causes of violent behavior are... challenging the notion that violence is something a person always does on purpose and should be punished for. Now it appears that many types of violence, especially impulsive violence, may be just like other mental disorders-a dysfunction of the brain-that can be treated and prevented."
