Abstract

Objective: Describe relationship between Autistic Spectrum Disorder and Schizophrenia. Methods: A child of eleven years old diagnosed Autistic Spectrum Disorder, who presents psychotic symptoms, is described. The relationship between Autistic Spectrum Disorder and Schizophrenia are revised in literature. Results: Longitudinal studies demonstrate that Autistic Spectrum Disorders develop Schizophrenia in rate not higher than for the general population. Differential diagnosis between Schizophrenia and Autistic Spectrum Disorder can be complicated. Some symptoms of autistic spectrum can be misinterpreted as psychosis. Autistic Spectrum Disorders can talk out loud to themselves and they have sensory stereotypes  which can be misinterpreted as hallucinations. Some beliefs and perceptions can be idiosyncratic and interpreted as psychotic. Some thought disorders (loose associations and illogical thinking) were not due to comorbid symptoms of schizophrenia, but pragmatic language abnormalities. Both disorders can present negative symptoms (social isolation, decrease emotional expression) and disorganization. Conclusion: Differentiating between the symptoms of autistic spectrum and Schizophrenia can be very complicated. Knowledge of abnormalities in development and the wide variety of manifestations of autistic spectrum will be needed to make a differential diagnosis with Schizophrenia.
