Abstract

Recent studies have shown that patients with schizophrenia who have an adolescent-symptom onset (before age 21) have a worse clinical course and greater frequency of cerebral abnormalities than those with an adult-onset (after age 25). However, Little is known about the neuropsychological functioning of these groups. A comprehensive neuropsychological examination was administered to groups of patients with schizophrenia with either an adolescent- or adult symptom-onset and a healthy control group. The adolescent-onset group performed worse than the adult-onset and control groups, particularly on measures of memory and executive function. The adult-onset:group also performed worse than the controls, but to a lesser extent than did the adolescent-onset group. Results are discussed with reference to hypotheses that adolescent-onset schizophrenia represents a distinct neurodevelopmental disease entity.
