Paranoid personality disorder
Definition
Paranoid personality disorder is a psychiatric condition characterized by extreme distrust and suspicion of others.
Alternative Names
Personality disorder - paranoid
Causes
Personality disorders are chronic patterns of behavior that cause lasting problems with work and relationships. The cause of paranoid personality disorder is unknown, but it appears to be more common in families with psychotic disorders like schizophrenia and delusional disorder, which suggests a genetic influence.
Symptoms
People with paranoid personality disorder are highly suspicious of other people. They are usually unable to acknowledge their own negative feelings towards other people.
Other common symptoms include:
- Concern that other people have hidden motives
- Expectation to be exploited by others
- Inability to collaborate
- Poor self image
- Social isolation
- Detachment
- Hostility
Exams and Tests
Personality disorders are diagnosed based on psychological evaluation and the history and severity of the symptoms.
Treatment
Treatment is difficult because people with this condition are often extremely suspicious of doctors. If accepted, medications and talk therapy can both be effective.
Outlook (Prognosis)
Therapy can limit the impact of the paranoia on the person's daily functioning.
Possible Complications
- Extreme social isolation
- Potential for violence
When to Contact a Medical Professional
If suspicions are interfering with relationships or work, a health care provider or mental health professional should be consulted.
