Agoraphobia

Disease Description (Causes and Symptoms)

• Definition summary: Agoraphobia is an anxiety disorder characterized by intense anxiety and avoidance of places or situations where it is difficult to be alone, leave quickly, or receive help (going out alone, crowds, standing in line, public transportation, bridges, tunnels, elevators, etc.).
• Main causes and pathophysiology: Previous experience of panic attacks is an important trigger. When a person experiences a panic attack outside the home, fear of recurrence can lead to avoidance behaviors, and the range of activities gradually becomes more limited. Neurotransmitters (GABA, norepinephrine, serotonin) and genetic and psychological factors are also involved. Avoidance behaviors maintain and intensify fear through negative reinforcement.
• Main symptoms: Intense anxiety and panic in agoraphobic situations, avoidance of going out alone, avoidance of crowded places, public transportation, and enclosed spaces, impaired interpersonal functioning, and a reduced range of activities. Approximately 3/4 of patients also have panic disorder.

Treatment Methods

• Non-pharmacological treatment (recommended first): Exposure therapy (gradual behavioral experiments and exposure) is central to cognitive behavioral therapy (CBT). It includes education, relaxation and breathing training, cognitive restructuring, gradual exposure, and correction of dysfunctional avoidance behaviors. Family support and a structured behavioral plan are effective.
• Pharmacological treatment: Used under the judgment of a psychiatrist. Generally, SSRIs (e.g., sertraline, paroxetine, etc.) and SNRIs (e.g., venlafaxine) are first-line medications, and short-term adjunctive use of benzodiazepines may be considered when symptoms are severe. Selection takes medical history, pregnancy, and drug interactions into account.
• Combination treatment: Combining CBT and medication is effective in moderate to severe cases or when panic disorder is also present.
• Lifestyle management and precautions: Maintain regular sleep and exercise; avoid caffeine, excessive alcohol, and illicit drugs; take and discontinue medications according to a specialist's instructions (do not stop abruptly). Check for the medication's sedative effects when driving or operating machinery.
• Management of complications: Depression, alcohol dependence, and reduced social or occupational functioning may occur — additional treatment (antidepressants, counseling, rehabilitation) may be considered when necessary.

Outpatient Visit Checkpoints (Including Preparation Items and Sample Questions)

• Preparation items (recommended to bring)
  • List of currently taken medications and supplements (name, dosage, and time of administration)
  • Previous diagnosis, test, and treatment records (mental-health-related medical records or test results)
  • Symptom diary (when and in what situations anxiety or panic occurred, duration, accompanying symptoms, and degree of avoidance)
  • Records of effects on daily functioning (difficulties at work, school, or home, and limitations due to avoidance)
  • Information on alcohol use, smoking, sleep, stress factors, and family history
• Information helpful to provide in advance during the outpatient visit
  • Frequency and severity of recent panic attacks
  • Previous responses to medications (effectiveness and side effects)
  • Whether there have been thoughts or behaviors related to self-harm or suicide (important for urgent assessment)

Examples of General Questions to Ask the Doctor

• "What are the advantages and disadvantages of the treatment you recommend (psychotherapy vs. medication)?"
• "If medication treatment is needed, what is the expected treatment duration and what are the common side effects?"
• "What are the ways to cope when symptoms recur (such as immediate coping strategies and breathing techniques)?"
• "What aspects of my lifestyle should I pay particular attention to?"

Examples of Condition-Specific Questions

• "Specifically, how is cognitive behavioral therapy (exposure therapy) conducted, and how often should I receive it?"
• "If panic disorder is also present, how do the medication and treatment strategies differ?"
