Schizotypal personality disorder, or simply schizotypal disorder, is a personality disorder that is characterized by a need for social isolation, anxiety in social situations, odd behavior and thinking, and often unconventional beliefs.

Although listed in the DSM-IV-TR on Axis II, schizotypal personality disorder is widely understood to be a “schizophrenia spectrum” disorder. Rates of schizotypal PD are much higher in relatives of individuals with schizophrenia than in the relatives of people with other mental illnesses or in people without mentally ill relatives. Technically speaking, schizotypal PD is an “extended phenotype” that helps geneticists track the familial or genetic transmission of the genes that are implicated in schizophrenia.[1]

There are dozens of studies showing that individuals with schizotypal PD score similar to individuals with schizophrenia on a very wide range of neuropsychological tests. Cognitive deficits in patients with schizotypal PD are very similar to, but somewhat milder than, those for patients with schizophrenia.[2]
