Studio del trasporto di serotonina nelle piastrine di pazienti in eta evolutiva con disturbi psicopatologici

Serotonin uptake abnormalities have been widely described in depressed adult patients. However, few studies analyzed this peripheral marker of serotonergic system in child neuropsychiatric disorders, despite the clinical use of serotonin uptake inhibitors in these syndromes. In this preliminary study, we investigated possible modifications of serotonin uptake in platelets from 34 child neuropsychiatric patients, aged 7-16, devided, according to the ICD10 classification, into the following cathegories: Attention Deficit Hyperactivity Disorder (ADHD), child autism, anxious syndromes, dysthymia. 10 normal age and sex related children were used as controls. Serotonin uptake was determined in fresh platelet preparations, using [³H]serotonin, according to the method of Arora and Meltzer. Platelet serotonin uptake was decreased by 60% (p
