What Causes Paranoid Personality Disorder?

There is no exact cause for paranoid personality disorder although there is evidence that links it to family history. It is likely that families with more than one member suffering from schizophrenia or delusional disorder may also have members that suffer from paranoia.

Some therapists also believe that the characteristics involved in paranoia might be acquired through learning. The condition might have its roots from childhood experiences. Proponents of this theory states that a child living in an environment full of anger and rage, without a means of predicting the outbursts or escaping such behavior, is more likely to demonstrate paranoia in order to manage stress. The behavior would then become a disorder when paranoid thoughts become integrated into their personality as they grow to become adults.

Studies involving identical and fraternal twins have linked genetic factors as contributors to paranoia. According to these studies, the genetic composition of an individual may lead to personality disorders, such as paranoid personality disorder. Aside from that, estimates on the level of genetic contribution to the development of personality disorders during childhood are identical to estimates of genetic contributions to personality disorders during adulthood.

As a personality disorder, paranoia is believed to have been caused by the poor handling of the areas responsible for regulating emotions. This is aggravated by the addition of other factors such as abuse, separation, or neglect. Likewise, paranoia can be triggered by major developments during adolescence and early adulthood. 2
