Risk Factors

Schizotypal personality disorder is more common in men. However, women can also have it. The risk may be higher in those with relatives who have schizophrenia.


Symptoms of schizotypal personality disorder may be:

  • Feeling uneasy with people
  • Problems forming relationships
  • Odd speech, dress, and grooming
  • "Magical" thinking—having special powers
  • Odd or paranoid thoughts
  • Problems showing some emotions
  • Talking to self


A mental health provider will ask about symptoms, health, and mental health. Mental health assessments will be done. The results will be used to confirm a diagnosis.


The goal is to treat the disorder. Other mental health problems may also need to be treated. Options may be:

  • Counseling—to help with coping
  • Group therapy—to help with social skills
  • Medicine—to treat thinking problems


There are no guidelines to prevent schizotypal personality disorder.
