How is schizotypal personality disorder diagnosed?

In order to be diagnosed with schizotypal personality disorder, a person must have a comprehensive emotional and behavioral evaluation with a mental health professional. Usually, a psychiatrist or psychologist will do this, although licensed clinical social workers and professional counselors also provide this service. During the evaluation, the doctor or therapist will question the person about their social experiences and social anxieties. The doctor will also ask the person about symptoms like magical thinking, delusions, and hallucinations. The specialist will analyze whether the person displays odd ways of dressing, strange behaviors, and inappropriate emotions. A diagnosis of schizophrenia will need to be ruled out to meet the criteria for schizotypal personality disorder. Since some medical conditions may mimic schizotypal personality disorder, lab tests and a physical exam may be conducted to rule out certain physical conditions.
