Differentiating Childhood-Onset Schizophrenia From Other Childhood Disorders

Abstract

Childhood-onset schizophrenia (COS) is a rare disorder in which symptoms of schizophrenia occur before the age of 13 years. This disorder often has a complicated presentation that can mimic other childhood disorders including post-traumatic stress disorder (PTSD), autism spectrum disorder (ASD), major depressive disorder (MDD) with psychosis, and generalized anxiety disorder (GAD) among others. This is further complicated by the low prevalence rate of COS which limits understanding of the disorder. Accurate and timely diagnosis is crucial as failure to do so has adverse implications for long-term treatment outcomes and prognosis. In this study, a rare case of a 12-year-old girl with childhood-onset schizophrenia and key findings that help differentiate it from other childhood disorders are reviewed to guide diagnosis and treatment.
