Causes of the Paranoid Personality Disorder
It is hard to tell the exact causes of various mental diseases unless the person had to go through some really stressful or shocking situation. A powerful shock might be the reason for the individual to behave weirdly for the rest of his or her life. Doctors stress there are three factors important to consider when trying to realize why PPD happened to someone: biological, psychological, social.
If at least one of the close family members used to suffer from schizophrenia or some other mental disorders, the chances to have troubles because of the paranoid personality disorder are also higher. Psychologists proved that a thin genetic link exists. Also, it is important to mind emotional traumas the kid used to go through. Besides, physical injuries or disorders could result in this problem as well.
