Pyromania

Disease description (causes and symptoms)

• Definition: A personality disorder characterized by unstable self-image, emotional regulation, and interpersonal relationships, with marked mood swings. Impulsive and self-destructive behaviors, chronic feelings of emptiness, and identity confusion are characteristic.
• Causes·pathophysiology: Rather than a single cause, a combination of factors such as genetic vulnerability, differences in brain structure and function (circuits related to emotional regulation), hormonal and immune changes, and environmental factors including childhood abuse and neglect contribute to the condition. Excessive emotional reactions, dissociation, and distorted perceptions of interpersonal relationships may occur in stressful situations.
• Main symptoms: Mood swings, extreme idealization and devaluation in interpersonal relationships, excessive fear of abandonment, identity confusion, impulsivity (substance abuse, overspending, risky behaviors), repeated self-harm and suicidal threats, and transient psychotic or dissociative symptoms.
• Possible comorbid conditions: Depression, bipolar disorder, anxiety disorders, substance use disorders, impulse control disorders, and other personality disorders (e.g., paranoid or antisocial personality disorder).

Treatment methods

• First principle: Ensuring safety (assessing the risk of self-harm and suicide and hospitalizing the patient when necessary); a psychotherapy-centered approach is the standard treatment.
• Psychotherapy (evidence-based):
  • Dialectical behavior therapy (DBT): The treatment with the most evidence for managing emotional regulation, interpersonal relationships, and self-destructive impulses.
  • Mentalization-based therapy (MBT), transference-focused psychotherapy (TFP), schema therapy, and other treatments have also been reported to be effective.
• Medication:
  • No specific medication treats the disorder as a whole. Symptom-based adjunctive use is recommended (symptomatic treatment).
  • SSRIs may be used for depressive and anxiety symptoms, while some mood stabilizers (lithium and anticonvulsants) or atypical antipsychotics may help relieve impulsivity and emotional instability in the short term.
  • When selecting medication, administer it cautiously, taking into account suicide risk, substance abuse, and side effects (including effects on interpersonal relationships).
  • Long-term use of benzodiazepines is not recommended because they may worsen dependence, memory impairment, and impulse-control problems.
• Emergency·inpatient treatment:
  • When the risk of self-harm or suicide is high, hospitalization and safety management, as well as medication and psychological stabilization, are necessary.
• Lifestyle management·self-care:
  • Maintain regular sleep, exercise, and nutrition; identify stress and triggers; establish a crisis plan (whom to contact, safe places, etc.); and avoid substance use.
• Precautions:
  • Treatment is long-term, and relapses and periods of instability may occur. Although building trust with the therapist may be difficult, continuing treatment is important for improving the prognosis.
  • Medication is intended to relieve symptoms and is not a fundamental treatment when used alone.
• Complications:
  • Repeated self-harm, suicide attempts and death (reports have associated the mortality rate with approximately 5–10%, depending on the report), substance abuse, and reduced interpersonal and occupational functioning.

Outpatient visit checklist (including example questions)

• Items to prepare and organize
  • A list of current medications (including prescription drugs, over-the-counter medicines, herbal medicines, and supplements), along with doses and times of administration
  • History of previous diagnoses, hospitalizations, and illnesses, as well as test records (copies if possible)
  • A record of recent symptom changes: frequency and severity of mood swings, whether there have been thoughts of self-harm or suicide and specific examples, and frequency of substance use
  • Recent lifestyle patterns (sleep, meals, work, and interpersonal relationships) and stressors
  • A list of people and support systems that can be contacted in a crisis
• Example questions for an outpatient visit (questions that patients or caregivers can prepare themselves)
  • How have your mood and impulse control been over the past few days or weeks?
  • Have you had thoughts of self-harm or suicide? Did you have a specific plan or make preparations?
  • Are medications or alcohol·drug use currently a problem?
  • In what situations do emotional outbursts or relationship conflicts occur frequently?

Examples of general questions to ask the doctor

• What psychotherapy is recommended for this condition, and what local resources (programs) are available?
• What is the purpose and expected benefit of the medication you plan to prescribe, and what are its main side effects?
• Where should I go, or what immediate actions should I take, when the risk of self-harm or suicide is high?
• How can the treatment duration and prognosis be predicted, and when can treatment effects be expected?
• What should I be careful about in daily life (work, dating, pregnancy, driving, etc.)?

Examples of condition-specific questions

• When emotional regulation becomes severely unstable and self-harm impulses recur, can we create a personalized safety plan (with specific steps) to use in an emergency?
• Please evaluate whether dialectical behavior therapy (DBT) is appropriate for me, and explain what procedures are required to participate in a DBT program locally?
