Spring/Summer - 2000 The following explains the conclusions in the scientific paper presented at the American Neuropsychiatric Association's annual meeting, February, 2000 in Ft. Meyers, Florida. This highly technical paper has been submitted for publication. Youth violence can be classified into two categories, Predatory Violence (planned aggression, carried out in cold blood) and Impulsive Violence (explosive aggression, carried out with a hot temper). While predatory violence may be a psychosocial problem, this paper presents evidence that impulsive or hot tempered violence is frequently related to an electrical disorder in the emotional center of the brain (the "limbic system"). This paper summarizes the evaluation and treatment of 3,000 juveniles in a Residential Treatment Center specializing in impulsive rage attacks. Of these, 85% showed electrical abnormalities in their limbic (emotion) brain. These juveniles were treated with high-end therapeutic blood levels of Carbamazepine (Tegretol), and anticonvulsant medication designed to stabilize their rage attacks. Outcome study results showed that 90% of those juveniles became stable, and remained stable over a two-year period, if their medication was continued. However, of those juveniles whose medication was reduced or eliminated after discharge, 85% had a return of rage attacks, with 71% requiring rehospitalization.
