Question

Quizplus · Accepted Answer

Schizotypal personality disorder is characterized by odd or eccentric behavior and beliefs, as well as difficulty forming close relationships. People with this disorder may seem strange or unconventional in their thoughts and behaviors, which may resemble those of schizophrenia to some degree. This may include idiosyncratic or idiosyncratic speech patterns, unusual beliefs or magical thinking, and a preference for solitude or unconventional interests. As such, it may be seen as an exaggerated form of "marching to a different drummer" or being original and idiosyncratic.
