Children and adolescents with autistic spectrum disorders are treated with neuroleptics to limit behavioral disturbances such as aggression, hyperactivity and self-injury. They may experience substantial weight gain when undergoing treatment with atypical antipsychotics actually employed. Topiramate (TPM) is an antiepileptic medication that is being progressively demonstrating a wider spectrum of action, mainly as an agent for weight control and as a mood stabilizer. It was administered to a group of children and adolescents with autistic spectrum disorders with the aim of reversing weight gain. This is an open study over an observation period of 18 months of 10 children and adolescents, eight males and two females, mean age 13 years, SD +/- 3.6, range 8-19 years with a diagnosis of autistic disorder or pervasive developmental disorder not otherwise specified according to DSM-IV. Starting dosage of TPM was 0.5 mg/kg followed by titration of 0.5 mg/kg on a weekly basis, up to 1-3 mg/kg/day as the maintenance dosage. Eight subjects were undergoing long-term treatment with risperidone, one with pimozide and one was temporarily not on antipsychotics. Six patients took TPM on a regular basis and four dropped out. Variable degrees of weight reduction were observed in four patients, two subjects showed weight increase. Behavioral adverse effects were observed in three patients causing rapid withdrawal of the medication. TPM should be used with caution in autistic spectrum disorders because this population has a high risk of behavioral disruption. (c) 2004 Elsevier B.V. All rights reserved.
