"There is a lack of research on the causes of HPD. Even though the causes for the disorder are not definitively known, it is thought that HPD may be caused by biological, developmental, cognitive, and social factors.

NEUROCHEMICAL/PHYSIOLOGICAL CAUSES. Studies show that patients with HPD have highly responsive noradrenergic systems, the mechanisms surrounding the release of a neurotransmitter called norepinephrine. Neurotransmitters are chemicals that communicate impulses from one nerve cell to another in the brain , and these impulses dictate behavior. The tendency towards an excessively emotional reaction to rejection, common among patients with HPD, may be attributed to a malfunction in a group of neurotransmitters called catecholamines. (Norepinephrine belongs to this group of neurotransmitters.)

DEVELOPMENTAL CAUSES. Psychoanalytic theory, developed by Freud, outlines a series of psychosexual stages of development through which each individual passes. These stages determine an individual's later psychological development as an adult. Early psychoanalysts proposed that the genital phase, Freud's fifth or last stage of psychosexual development, is a determinant of HPD. Later psychoanalysts considered the oral phase, Freud's first stage of psychosexual development, to be a more important determinant of HPD. Most psychoanalysts agree that a traumatic childhood contributes towards the development of HPD. Some theorists suggest that the more severe forms of HPD derive from disapproval in the early mother-child relationship.

Another component of Freud's theory is the defense mechanism. Defense mechanisms are sets of systematic, unconscious methods that people develop to cope with conflict and to reduce anxiety. According to Freud's theory, all people use defense mechanisms, but different people use different types of defense mechanisms. Individuals with HPD differ in the severity of the maladaptive defense mechanisms they use. Patients with more severe cases of HPD may utilize the defense mechanisms of repression, denial , and dissociation.

BIOSOCIAL LEARNING CAUSES. A biosocial model in psychology asserts that social and biological factors contribute to the development of personality. Biosocial learning models of HPD suggest that individuals may acquire HPD from inconsistent interpersonal reinforcement offered by parents. Proponents of biosocial learning models indicate that individuals with HPD have learned to get what they want from others by drawing attention to themselves.

SOCIOCULTURAL CAUSES. Studies of specific cultures with high rates of HPD suggest social and cultural causes of HPD. For example, some researchers would expect to find this disorder more often among cultures that tend to value uninhibited displays of emotion.

PERSONAL VARIABLES. Researchers have found some connections between the age of individuals with HPD and the behavior displayed by these individuals. The symptoms of HPD are long-lasting; however, histrionic character traits that are exhibited may change with age. For example, research suggests that seductiveness may be employed more often by a young adult than by an older one. To impress others, older adults with HPD may shift their strategy from sexual seductiveness to a paternal or maternal seductiveness. Some histrionic symptoms such as attention-seeking, however, may become more apparent as an individual with HPD ages.
