  • Paranoid personality disorder is a psychiatric diagnosis that denotes a personality disorder with paranoid features. It is characterized by an exaggeration of the cognitive modules for sensitivity to rejection, resentfulness, distrust, as well as the inclination to distort experienced events. Neutral and friendly actions of others are often misinterpreted as being hostile or contemptuous.

    People with this disorder tend to have excessive trust in their own knowledge and abilities and usually avoid close relationships with others. They search for hidden meanings in everything and read hostile intentions into the actions of others. They are quick to “challenge the loyalties of friends and loved ones and often appear cold and distant to others�?. They usually shift blame to others and tend to carry long grudges.

    Based on little or no evidence, they suspect that others are out to harm them and usually find hostile or malicious motives behind other people's actions.
