Paranoid personality disorder is a chronic condition characterized by pervasive feelings of suspicion and paranoia. People with paranoia disorder generally feel that people are out to harm them in some way, and this constant feeling of paranoia or suspicion is the primary symptom of the disorder.

What Is Paranoia Disorder?

Suspicion and worry are emotions that many people experience from time to time. Usually, there’s a good reason for these feelings–for example, if you’ve found out that your company is considering layoffs, you might start anticipating bad news and second-guessing everything that happens around the office. Paranoia disorder is different because it involves feelings of suspicion and fear of being harmed when no actual threat is present.

People who display paranoid symptoms are convinced that other people intend to harm or humiliate them in some way. As a result, they do not trust other people. They view strangers and even people they know well as threatening. A person with paranoid personality disorder tends to misconstrue innocuous comments as aggressive or insulting. For example, if you compliment a paranoid person about his new car, he may take it as an attack on his spending habits.

People with paranoid personality disorder are often hostile to others. Relationships are difficult because they tend to suspect significant others of infidelity, even without any evidence to suggest it. However, despite their tendency to misinterpret words and gestures, people with paranoia disorder still have a firm grip on reality. They are not prone to the hallucinations or psychotic episodes seen in some other disorders.
