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
