A possible cause of schizotypal personality disorder is a family history of schizophrenia disorders or other mental health conditions.
Schizotypal personality disorder is characterized by unusual or eccentric behavior in its sufferers, who typically have few or no intimate connections. Most of the time, they are unaware of how connections develop or how their actions affect others. They might also misjudge the intentions and actions of others, leading to a strong mistrust of them. They may have delusions but do not have hallucinations.
