Abstract

Atypical antipsychotics have been shown to improve disruptive and repetitive behaviors in pervasive developmental disorders (PDDs), but they require assessment of potential side effects. This is the first placebo-controlled trial of olanzapine in the treatment of children and adolescents with PDD. Eleven patients with a diagnosis of either autism, Asperger's syndrome, or PDD not otherwise specified (PDD-NOS) and aged 6-14 years were randomized into an 8-week double-blind, placebo-controlled, parallel treatment study with olanzapine. There was a significant linear trend x group interaction on the Clinical Global Impressions- Improvement (CGI-I) and 50% on olanzapine versus 20% on placebo were responders. Olanzapine was associated with significant weight gain (7.5 +/- 4.8 lbs vs. 1.5 +/- 1.5 lbs on placebo). Olanzapine may be a promising treatment for improving global functioning of PDDs, but the risk of significant weight gain remains a concern. Additional studies are needed to determine the efficacy and safety of olanzapine in the treatment of children with PDD.
