Paranoid personality disorder is an unwarranted tendency to interpret the actions of other people as deliberately threatening or demeaning. The disorder, surfacing by early adulthood, is manifested by an omnipresent sense of distrust and unjustified suspicion that yields persistent misinterpretation of others’ intentions as being malicious. People with a paranoid personality disorder are usually unable to acknowledge their own negative feelings toward others but do not generally lose touch with reality. They will not confide in people, even if they prove trustworthy, for fear of being exploited or betrayed. They will often misinterpret harmless comments and behavior from others and may build up and harbor unfounded resentment for an unreasonable length of time.
People with this disorder typically exhibit a strong need for self-sufficiency, are rigid and often litigious. Because of their avoidance of closeness with others, they may appear calculating and cold. Usually men are diagnosed with it more than women.
Paranoid personality disorder should not be diagnosed if the pattern of suspicious behavior occurs exclusively during the course of schizophrenia or another psychotic disorder.
The specific cause of this disorder is unknown. It appears to be more common in families with psychotic disorders such as schizophrenia and delusional disorder, which suggests that genes may be involved. Paranoid personality disorder can result from negative childhood experiences fostered by a threatening domestic atmosphere. It is prompted by extreme and unfounded parental rage and/or condescending parental influence that cultivate profound childhood insecurities.
If you or your loved one is suffering from Paranoid PD then consult earliest with the psychiatrist.
