Disease Description (Causes and Symptoms)
- Definition summary: Histrionic personality disorder (HPD) is a personality disorder in which excessive emotional expression and attention-seeking behavior persist and interfere with interpersonal relationships and occupational functioning. It usually develops in early adulthood and appears consistently across multiple situations.
- Main pathophysiology: A combination of genetic predisposition (high concordance rates in twin studies) and interactions between childhood rearing environments and temperament is thought to contribute to the formation of excessive emotional expression and interpersonal strategies. From a psychodynamic perspective, fixation at a developmental stage has also been proposed as a cause.
- Main symptoms (features):
- Feels uncomfortable when unable to attract other people's attention
- Exaggerated and superficial emotional expression (mood swings, theatrical behavior)
- May display inappropriately sexual or seductive behavior
- Is easily influenced by others and highly suggestible
- Believes that their interpersonal relationships are closer than they actually are
- Behavior aimed at attracting attention through appearance or impression management
- Possible coexisting conditions: Depression, anxiety disorders, other personality disorders such as borderline, antisocial, and narcissistic personality disorders, substance use disorder, and in some cases coexisting psychotic symptoms (e.g., schizophrenia)
Treatment Methods
- Psychotherapy (first-line treatment):
- Long-term psychotherapy is recommended. Therapeutic approaches may include psychodynamic therapy, cognitive behavioral therapy (CBT), interpersonal psychotherapy (IPSRT or structured interpersonal therapy), and group therapy (including interpersonal skills training), selected according to the patient's problems and therapeutic goals.
- Treatment goals: Emotion labeling, recognition of impulsive and attention-seeking behaviors, improvement of interpersonal skills, and learning boundary-setting skills. An empathic attitude and consistent boundary setting are important.
- Medication (adjunctive use):
- There are no approved medications specifically indicated for histrionic personality disorder itself. For symptoms or coexisting conditions such as depression or anxiety, antidepressants (such as SSRIs), anxiolytics (for short-term treatment), and, if necessary, low-dose antipsychotics may be considered.
- Medications are primarily intended to relieve symptoms (e.g., depression, anxiety, and impulse-control problems) and treat coexisting conditions.
- Lifestyle management and education: Stress, sleep, medication, and alcohol management; maintaining a regular routine; and building a healthy social support network. Education for family members and others close to the patient (how to set boundaries and avoid excessive compensation or reinforcement) can help improve treatment effectiveness.
- Precautions: Because the patient's need for attention during treatment may affect the therapeutic relationship, the therapist must maintain consistent boundaries and a professional attitude. If self-harm or suicide risk is suspected, immediate assessment and appropriate intervention are necessary.

Examples of General Questions to Ask the Doctor
- What are the expected effects and possible side effects of this medication (or treatment)?
- What treatment duration and treatment goals are recommended?
- If medication treatment is needed, what is the management plan when stopping the medication?
- What specific ways can family members or people close to me help during treatment?
- What specific strategies (e.g., stress-coping methods and interpersonal skills) can help relieve symptoms in daily life?
Examples of Customized Questions by Condition
- How can medicine explain the effects on my interpersonal relationships of specific behaviors I engage in to attract other people's attention (e.g., excessive exposure or dramatic expression)?
- If there are exercises (assignments) or techniques that can help me recognize my emotions more specifically during treatment, which ones would you recommend?
