$UWMC Whoever is annoyed by "Doug the psycho", understand his serious medical condition: "Histrionic Personality Disorder (HPD) is defined by the American Psychiatric Association as a personality disorder characterized by a pattern of excessive attention-seeking behaviors, usually beginning in early childhood, including inappropriate seduction and an excessive desire for approval. People diagnosed with the disorder are said to be lively, dramatic, vivacious, enthusiastic, and flirtatious. HPD lies in the dramatic cluster of personality disorders. People with HPD have a high desire for attention, make loud and inappropriate appearances, exaggerate their behaviors and emotions, and crave stimulation. They may exhibit sexually provocative behavior and express strong emotions with an impressionistic style. Associated features include egocentrism, self-indulgence, continuous longing for appreciation, and persistent manipulative behavior to achieve their own needs."
