• Fifty-eight violent offenders and impulsive fire setters were followed up for an average of 3 years after release from prison. Recidivists who committed a new violent offense or arson had significantly lower cerebrospinal fluid 5-hydroxyindoleacetic acid and homovanillic acid concentrations and blood glucose nadirs after oral glucose challenge than did nonrecidivists. A discriminant analysis, based on the blood glucose nadir and cerebrospinal fluid 5-hydroxyindoleacetic acid concentration, correctly classified 84.2% of the subjects.
