paranoid personality disorder
Paranoid personality disorder is defined by a distrust of others and a continuous suspicion of their intentions. The individual lives in a hostile world and firmly believes that others have sinister motives that are threatening or demeaning. This is usually without good evidence and those suffering from paranoid personality disorder will often dwell on trivial things.
Sufferers will often avoid any close relationships with others, and tend to have extreme trust in their own knowledge and capabilities. Perceptions of how others are behaving may lead to angry or aggressive outbursts, as sufferers are hypersensitive and unforgiving.
This disorder eventually leads to the individual appearing cold and distant, constantly challenging the loyalties of friends and loved ones. They may also be jealous, secretive and scheming. This can result in social isolation as the individual may stay at home, planning how to react to a perceived attack. Any attempt of communication may be rejected as the sufferer becomes more reclusive.
