Schizotypal Personality Disorder (STPD) is a personality disorder characterized by persistent patterns of unusual thinking, eccentric behavior, social anxiety, and difficulty forming close relationships. Although it shares some features with schizophrenia, people with STPD usually remain aware of reality and do not experience persistent psychosis.

- Lack of close friends outside immediate family

When to See a Doctor for Schizotypal Personality Disorder?
