A personality disorder is a type of mental disorder in which you have a rigid and unhealthy pattern of thinking, functioning, and behaving. A person with a personality disorder has trouble perceiving and relating to situations and people.

Early childhood events, genetic predispositions, and environmental factors can all play roles in personality disorders. Experts do not entirely agree on the primary reasons that some people develop these illnesses, and the exact causes may vary among individuals.
Personality is the combination of thoughts, emotions and behaviors that makes you unique. It’s the way you view, understand and relate to the outside world, as well as how you see yourself. Personality forms during childhood, and can be shaped through an interaction of:
- Your genes. Certain personality traits may be passed on to you by your parents through inherited genes. These traits are sometimes called your temperament.
- Your environment. This involves the surroundings you grew up in, events that occurred, and relationships with family members and others.
