Overview
Schizotypal personality disorder is a mental health condition in which a person has trouble with relationships and disturbances in thought patterns, appearance, and behavior.

What are the symptoms of Schizotypal personality disorder?

 * People with schizotypal personality disorder may be very disturbed. Their odd behavior may look like that of people with schizophrenia. For example, they may also have unusual preoccupations and fears, such as fears of being monitored by government agencies.


 * More commonly, however, people with schizotypal personality disorder behave oddly and have unusual beliefs (such as aliens). They cling to these beliefs so strongly that it prevents them from having relationships.


 * People with schizotypal personality disorder feel upset by their difficulty in forming and keeping close relationships. This is different from people with schizoid personality disorder, who do not want to form relationships.

What causes Schizotypal personality disorder?

 * The exact cause is unknown. Genes are thought to be involved, because this condition is more common in relatives of schizophrenics.


 * Schizotypal personality disorder should not be confused with schizophrenia. People with schizotypal personality disorder can have odd beliefs and behaviors, but they are not disconnected from reality and usually do not hallucinate.


 * Hallucinations, delusions (fixed, false beliefs), and loss of touch with reality are hallmarks of psychosis. People with schizotypal personality disorder do not usually have psychotic symptoms.


 * Between 30% and 50% of people with schizotypal personality disorder also have a major depressive disorder. A second personality disorder, such as paranoid personality disorder, is also common with this condition.
