Cognitive Impairment in Adolescents With Schizophrenia

Published Online:1 Apr 2006https://doi.org/10.1176/ajp.154.11.1613

Abstract

OBJECTIVE: The purpose of this study was to determine whether adolescent schizophrenia is characterized by neuropsychological deficits. METHOD: The performance on a battery of neuropsychological tests of 17 adolescents with schizophrenia (mean age=15.71 years) was compared with that of 17 normal adolescents (mean age=15.12 years). RESULTS: Compared with the normal subjects, the patients were impaired on 10 of the 13 measures; larger effect sizes were shown for measures involving working memory and attention than for those involving secondary memory, generative naming, and executive functions. CONCLUSIONS: Adolescents with schizophrenia have generalized cognitive dysfunction, which is most apparent on tests of attention and working memory. (Am J Psychiatry 1997; 154:1613–1615)
