Causes
The cause of histrionic personality disorder is unknown, but childhood events such as deaths or illnesses in the immediate family (which present constant anxiety), divorce of parents, and genetics may be involved. HPD is more often diagnosed in women than men; men with some similar symptoms are often diagnosed with narcissistic personality disorder.
Little research has been conducted to determine the biological sources, if any, of this disorder. Psychoanalytic theories incriminate authoritarian or distant attitudes by one (mainly the mother) or both of parents, along with conditional love based on expectations the child can never fully meet.
