Monoamines, glucose metabolism, and impulse control.

We had studied cerebrospinal fluid monoamine metabolite concentrations and glucose metabolism in 58 violent offenders and impulsive fire setters in the early 1980s. We performed a follow-up study investigating recidivist crimes after release from prison and histories of suicide attempts using behavioral, diagnostic, and biochemical variables to discriminate subjects with recidivism and suicide attempts from subjects without recidivism and suicide attempts. Biochemical variables discriminated significantly between the groups.
