Paranoid personality disorder (PPD) is a type of eccentric personality disorder. An eccentric personality disorder means that the person’s behavior may seem odd or unusual to others. An individual with paranoid personality behavior is very suspicious of other people. They mistrust the motives of others and believe that others want to harm them. Additional hallmarks of this condition include being reluctant to confide in others, bearing grudges, and finding demeaning or threatening subtext in even the most innocent of comments or events. A person with PPD can be quick to feel anger and feel hostile toward others.
PPD usually appears in early adulthood. According to the Cleveland Clinic, PPD appears to be more common in men than women.
