Antisocial personality disorder is a psychiatric condition that causes an ongoing pattern of manipulating others and violating their rights. People with this disorder do not follow society’s norms and often break the law. It is characteristic for people with this diagnosis to be entirely careless about other people's feelings and pain. They also show a pervasive pattern of no regret, together with irresponsible decisions.

Seeking treatment is important not only to help the person with the disorder, but also to protect other people who may be affected by the person’s behavior.

This disorder is caused by a combination of genetic factors and the person’s environment, especially the family environment. Researchers believe that biological factors may contribute, such as abnormal chemistry in the nervous system and impairment in the parts of the brain that affect judgment, decision-making, planning, and impulsive and aggressive behavior.
