Schizotypal Personality Disorder

Schizotypal personality disorder is characterized by deficits in social and interpersonal skills, highlighted by a reduced ability to form close relationships, occurring in the setting of eccentric behavior and cognitive or perceptual distortions. Symptoms such as restricted affect and social isolation in schizotypal personality disorder may share similarities with those found in schizoid personality and paranoid personality disorders. The symptoms of schizotypal personality disorder must be distinguished from neurodevelopmental disorders, personality changes due to another medical condition,  substance use disorders, and other mental disorders with psychotic symptoms.
