Paranoid Personality Disorder (PPD) is classified under Cluster A personality disorders, which are characterized by odd or eccentric behaviors. Individuals with PPD display a consistent and pervasive distrust and suspicion of others. They often believe that others have hidden motives and are out to exploit, harm, or deceive them—even in the absence of concrete evidence. This disorder can severely affect interpersonal relationships, as the individual may misinterpret innocent remarks or casual looks as threats.
