Until very recently, most mental-health practitioners believed that personality disorders were incurable because unlike mood disorders, such as depression and anxiety, personality disorders consist of long-standing, pervasive patterns of behavior that are very much a part of one’s personality. In other words, personality disorders are ego-syntonic, which means the behaviors seem in sync with the person’s self-concept; as a result, people with these disorders believe that others are creating the problems in their lives.
