Behavior Disorders

Behavior disorder is a general term for persistent, inappropriate action or emotion that occurs under normal circumstances. Behavior disorders are also defined as the pattern of behaviors in individuals that have lasted for at least six months. They are disruptive, resulting in problems at school, home, or in social situations. This behavior causes persistent and repetitive actions that are not acceptable in society. It also creates distress in the daily life of the person.
