Study Summary

This study was developed in order to assess the effects of risperidone (Risperdal) as compared with placebo on cognitive-motor performance (attention, memory, and hand steadiness) and body movements. We propose to study the effects of risperidone on cognitive-motor performance in children already medicated for severe conduct problems. We would also like to look at safety by assessing these children for dyskinetic movements. We already have a sizable cohort of children maintained on risperidone. Our hypotheses are as follows: 1. Risperidone will have no adverse effects on cognitive-motor performance in children who have received maintenance therapy for 4 to 20 months. 2. Children tested during placebo will show no more dyskinetic movements than during risperidone treatment (i.e., there will be no unmasking of tardive dyskinesia).
