Abstract
Prader-Willi syndrome (PWS) is a quite rare multi-systemic genetic disorder strongly asso-ciated with psychiatric illness in adults, especially psychosis. This report presents a 16 year old female with PWS and symptoms of brief psychotic disorder with a complete resolution of symptoms under aripiprazole medication. However, an exacerbation occurred after ari-piprazole reduction. Apart from a weight gain of about 2 kg over the course of two years, no adverse effects could be found. This first report on the use of aripiprazole in a subject with PWS and psychosis suggests that aripiprazole might be a promising treatment ap-proach in this distinct group of patients.
