In simple words: Paranoid personality disorder (PPD) is a mental health condition where people have a strong and unreasonable mistrust of others, believing that people are trying to harm them or deceive them, even when there's no evidence to support these beliefs.

Paranoid personality disorder (PPD) is characterized by a pervasive distrust and suspiciousness of others, such that their motives are interpreted as malevolent. This pattern begins by early adulthood and is present in a variety of contexts.

Example 1: A 30-year-old male consistently accuses his coworkers of sabotaging his work, despite evidence to the contrary. He is reluctant to confide in others and holds grudges for perceived slights., A 45-year-old female is preoccupied with doubts about the loyalty of her friends and spouse. She reads hidden meanings into benign remarks and is quick to counterattack when she feels criticized., A 25-year-old male is excessively secretive and guarded. He suspects that others are exploiting, harming, or deceiving him, and is unforgiving of past transgressions.

Documentation should include a comprehensive psychiatric evaluation outlining the patient's symptoms, history, and behavior patterns. Supporting evidence from collateral sources, such as family members or friends, can also be helpful.
