Paranoid personality disorder is a psychiatric condition in which a person has a long-term distrust and suspicion of others, but does not have a full-blown psychotic disorder such as schizophrenia.

What are the symptoms of Paranoid personality disorder?

 * People with paranoid personality disorder are highly suspicious of other people. As a result, people with this condition severely limit their social lives.
