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.
