Schizotypal personality disorder, or simply schizotypal disorder, is a personality disorder that is characterized by a need for social isolation, odd behaviour and thinking, and often unconventional beliefs such as being convinced of having extra sensory abilities.

There is a high rate of comorbidity with other personality disorders. McGlashan et al. (2000) stated that this may be due to overlapping criteria with other personality disorders, such as avoidant personality disorder and paranoid personality disorder^[1].
