histrionic personality disorder, a disorder characterized by dramatic, reactive, and intensely exaggerated behavior, which is typically self-centered. It results in severe disturbance in interpersonal relationships that can lead to psychosomatic disorders, depression, alcoholism, and drug dependency. Symptoms include emotional excitability, such as irrational angry outbursts or tantrums; abnormal craving for activity and excitement; overreaction to minor events; manipulative threats and gestures; egocentricity; inconsiderateness; inconsistency; and continuous demand for reassurance generated by feelings of helplessness and dependency. A person with this disorder is perceived by others as vain, demanding, superficial, self-centered, and self-indulgent. The disorder is more prevalent in women than in men and is treated by various psychotherapies, depending on the individual and the severity of the condition. See also narcissistic personality disorder.
