Definition

Schizotypal personality disorder is a personality disorder characterized by odd behaviors, beliefs, and/or thoughts, and difficulties in social situations. People with personality disorders are not aware that their thoughts and behaviors are inappropriate.

Causes

It is not clear what causes personality disorders, but it is likely a combination of genetic (inherited) factors and a person's environment.

Frontal Lobe of the Brain

Although the cause of personality disorders is not clear, it is believed that the frontal lobe is where personality and impulses arise.

Risk Factors

A risk factor is something that increases your chance of getting a disease or condition.

The following factors are thought to increase the risk of schizotypal personality disorder:

Gender: male
