title: Serotoninergic dysfunction in the 47, XYY syndrome.
abstract: In six XYY patients suffering from aggressiveness and admitted by order of law into a security setting for acts of violence, the estimation of cerebrospinal fluid amine metabolites before and after a probenecid test revealed a clear decrease in the turnover of central serotonin (5-HT) while that of dopamine (DA) was unchanged. The treatment with the 5-HT precursor, L-5-hydroxytryptophan (L-5-HTP), in five of the XYYs resulted in a clinical status equivalent to that observed when the patients were previously treated by conventional neuroleptics.
