- Panic disorder is a type of anxiety disorder characterized by recurrent panic attacks even in situations where no clear actual danger is present.
- Although the exact cause remains unidentified, genetic predisposition, biological and chemical factors in the brain, environmental factors, and significant stress may be involved.
- In panic disorder, anticipatory anxiety—the fear that another attack might occur after a sudden panic attack—and situational avoidance can reinforce each other.
- The typical presentation involves sudden intense fear or loss of control, accompanied by palpitations, sweating, trembling, dyspnea, chest pain, dizziness, and nausea.
- Family history, female sex, onset in late adolescence or early adulthood, significant stress, and especially experiences of childhood trauma may be associated with increased risk, although individual differences are substantial.
- Panic attacks can occur at any time without warning and may last from several minutes to over an hour; while some improve after one or two attacks, others experience persistent recurrent attacks and avoidance.
- Diagnosis is made by confirming medical history and symptoms, examining causes related to physical illnesses or drugs/substances, and, if necessary, comprehensively integrating physical examinations, blood tests, cardiac evaluation, and psychological assessment.
- Because the chest pain, dyspnea, and palpitations of a panic attack can overlap with other physical illnesses, panic disorder should not be diagnosed based on symptoms alone.
- Management focuses on reducing symptoms and avoidance and restoring daily functioning; psychotherapy, pharmacotherapy, lifestyle adjustments, and support systems may be combined as appropriate for the situation.
- Current treatments may include psychotherapy, such as cognitive behavioral therapy, and antidepressants or anti-anxiety medications; the choice is determined by considering an individual's symptoms and risks.
