Schizotypal Personality Disorder

Schizotypal personality disorder is a personality disorder. It is marked by severe social anxiety, thought disorder, paranoid ideation, derealization, and transient psychosis. It is defined by The Diagnostic and Statistical Manual of Mental Disorders, DSM-5. The DSM-5 is published by the American Psychiatric Association.

Diagnosis requires at least five of these:

• Ideas of reference
• Strange beliefs or magical thinking
• Abnormal perceptual experiences
• Strange thinking and speech
• Paranoia
• Inappropriate or constricted affect
• Strange behavior or appearance
• Lack of close friends
• Excessive social anxiety that does not abate and stems from paranoia rather than negative judgments about self
