Personality disorders (Cluster B, Histrionic)
Overview
Plain-Language Overview
Histrionic personality disorder is a mental health condition that affects a person's emotions and behavior. It involves patterns of excessive emotionality and attention-seeking that can impact relationships and daily functioning. This disorder primarily affects the brain's emotional regulation and social interaction systems. People with this condition often feel uncomfortable when they are not the center of attention and may use dramatic or provocative behavior to gain approval. It can lead to difficulties in maintaining stable relationships and cause distress in social or work environments. The condition is part of a group called Cluster B personality disorders, which are characterized by dramatic and erratic behaviors.
Clinical Definition
Histrionic personality disorder is a Cluster B personality disorder characterized by a pervasive pattern of excessive emotionality and attention-seeking behavior beginning in early adulthood. The core pathology involves dysregulation of affect and interpersonal relationships, often manifesting as inappropriate seductiveness, rapidly shifting emotions, and a need for approval. The etiology is multifactorial, involving genetic predisposition and environmental influences such as early childhood experiences. Clinically, patients display dramatic, theatrical behavior, superficial relationships, and discomfort when not the center of attention. This disorder significantly impairs social and occupational functioning and is associated with comorbid mood and anxiety disorders. Diagnosis is based on clinical history and behavioral observation, with no specific laboratory tests.
