Is schizotypal personality disorder related to schizophrenia?

Douglas E. Severance, MD
Family Medicine
With schizotypal disorder, people may show symptoms similar to those of schizophrenia. One key difference between schizotypal disorder and schizophrenia is that people with schizotypal disorder do not have hallucinations and delusions. However, people with schizotypal disorder are more likely to have relatives with schizophrenia than the average person, so there may be a genetic link between the two illnesses. Symptoms of schizotypal disorder include:

- social difficulties
- strange thoughts and behavior
- trouble maintaining one's appearance
- high risk of major depression

People with schizotypal disorder may appear to have schizophrenia because they have paranoid thoughts and strange beliefs about paranormal subjects. These odd behaviors and beliefs make it difficult to have normal relationships with other people. As with schizophrenia, antipsychotic medications and psychotherapy are the preferred treatments for schizotypal disorder.
