Schizophrenia is a serious mental illness that usually has its onset in early adulthood, with a typical age at onset between ages 20 and 25 (Goldner, Hsu, Waraich, & Somers, 2002). Although much less common, the illness can also occur in children and adolescents. These early-onset cases are often characterized by more severe symptoms with a worse prognosis, and the patients are more likely to be male (Rapoport & Inoff-Germain, 2000). However, the results of genetic and neurobiological studies generally suggest that childhood-onset schizophrenia and adult-onset schizophrenia are the same disorder and have common etiologic factors. Thus, the same diagnostic criteria are used to diagnose children and adults (American Psychiatric Association [APA], 2000).
