[edit intro]

Schizotypal personality disorder is identified as a personality disorder characterized by social isolation, as well the exhibition of odd behavior and thinking, often accompanied by unconventional belief systems. ^[1] There is often a high rate of comorbidity with other personality disorders, which may be due to considerable criteria overlap with other personality disorders, specifically avoidant personality disorder and paranoid personality disorder. ^[2] Traits of paranoid ideation and unusual experiences tend to remain stable over time, while odd behavior and constricted affect are the least prevalent and most changeable.^[3]

Schizotypal personality disorder falls within the A cluster of personality disorders, along with Paranoid personality disorder and Schizoid personality disorder ^[1]

Diagnostic criteria[edit]

Note: The American Psychiatric Association, which publishes the Diagnostic and Statistical Manual of Mental Disorders, forbids the unauthorized reproduction of their diagnostic criteria. A narrative of the DSM-IV-TR criteria follows.

Treatment[edit]

Schizotypal personality disorder shares many similarities with schizophrenia and tends to respond to the same psychoactive medications. ^[4]
