Persistent Depressive Disorder (PDD) is a mood disorder that can stay for a long period of time like two years. It causes a deep feeling of sadness and hopelessness affecting the behavior of a person, beliefs, and emotion.
A person with Paranoid Personality Disorder usually has a high level of distrust and suspicion of others. Individuals with this kind of personality disorder usually see and view other people as someone who might be out to harm, threaten, betray or even exploit them. This type of personality disorder is also more common in young adults and can cause patients to misread people and redefine simple gestures as something malevolent or harmful to them and their well being.
