New Findings in Early-Onset Schizophrenia

The Treatment of Early-Onset Schizophrenia Spectrum Disorders (TEOSS) study, funded by the NIMH, was a multicenter, controlled treatment trial of children and adolescents.1 The aim of the TEOSS study was to compare the efficacy and safety of risperidone and olanzapine with that of a traditional antipsychotic agent—molindone.

In this double-blind, parallel-group study, patients were randomized to receive risperidone, olanzapine, or molindone for 8 weeks followed by a 44-week, double-blind maintenance phase for responders. A total of 119 children and adolescents were randomized in the study. The results of the study, which should be reported in the near future, will provide needed information about the safety and tolerability of antipsychotic medications in youths with schizophrenia spectrum disorders.

The clinical characteristics of this large sample were recently reported and provide important information about the demographics and severity of illness in children and adolescents with early-onset schizophrenia and schizoaffective disorder.2 The mean age of onset of illness was 11.1 years. At the time of enrollment, the mean age of the patients was 13.8 years. The sex distribution was 66% male and 34% female. The racial breakdown was 62% white, 31% African Amer-ican, 3.4% Asian, 2.5% mixed, and 0.8% Pacific Islander. The average IQ of the sample was 93. Most of the youths lived with their family, 4% were hospitalized, and 7% lived in a group home or residential facility.
