Personality disorders affect 10-15% of the adult US population. A personality disorder is a very rigid pattern of inner experience and outward behavior. According to SAMHSA over 8.9 million persons have co-occurring disorders; that is that they have both mental and substance use disorders.

One such disorder is Paranoid Personality disorder (PPD). Treatment, diagnosis, and prognosis can be challenging due to the nature of this disorder. Individuals who are diagnosed with PPD are often also diagnosed with Substance Use Disorder (SUD). One question that studies hope to answer is whether or not SUD can cause PPD, or vise versa. Having an individual with co-occurring SUD can prove even more difficult; however with a PPD&SUD sufferer willing to participate in their treatment, the outlook becomes more positive. Though it is not known what causes PPD many it is most likely that it is caused by several different factors.

In some instances, Paranoid Personality Disorder may appear as the premorbid antecedent of Delusional Disorder or Schizophrenia.” In order for an individual to be diagnosed with PPD he or she must be 18 years or older and display at least four of the following traits: a) chronically suspicious that people are lying
