Pat claims his father, John, is delusional, violent and paranoid, and that he is terrified of him. However, John denies the accusations and says that his son is the one who is violent and that he believes Pat suffers from a genetically transferred imbalance which has caused him to have a mental illness. Watch their story here.  

After examining some of John’s behavior, Dr. Phil says to him, “If I were still practicing and I were seeing you in my office, on my short list of considerations would be a paranoid personality disorder, ” which he explains as a pattern of distrust and suspiciousness, such that others motives are interpreted as malevolent.

According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), some of the traits associated with the disorder include:

• Suspects without sufficient basis that others are exploiting, harming or deceiving them
• Preoccupied with doubts about the loyalty or trustworthiness of friends or family
• Reluctant to confide in others
• Reads hidden, demeaning or threatening meanings into benign remarks or events
• Bears grudges
• Reacts quickly to perceived attacks on their character
• Has recurrent suspicions without justification

“Not with me,” John says.

On Tuesday’s episode, Dr. Phil offers John help to determine what may be causing his behavior. Will he accept? Watch more here.
