Panic Attack Triggers and Risk Factors: Genetics, Stress, Medical Conditions, and More

Panic attacks arise from an interplay of predisposing vulnerabilities and precipitating triggers.

Risk Factors

• Genetics: Heritability ~40%; specific loci under study (e.g., COMT, BDNF).
• Temperament: High neuroticism, anxiety sensitivity, behavioral inhibition.
• Early adversity: Childhood trauma, abuse, neglect.
• Acute stress: Loss, job change, relationship breakdown.

Direct Triggers

• Medical conditions: Hyperthyroidism, hypoglycemia, pheochromocytoma, cardiac arrhythmias, vestibular dysfunction.
• Substances: Caffeine, nicotine, stimulants, cannabis, alcohol withdrawal.
• Medications: SSRIs (initial activation), bronchodilators, thyroid hormone.
• Interoceptive cues: Somatic sensations (palpitations, dyspnea) misinterpreted as catastrophe.

Vicious Cycle

Fear of future attacks → hypervigilance to bodily sensations → increased anxiety → more attacks (panic disorder).

Management

CBT (gold standard), SSRIs/SNRIs, benzodiazepines (short-term), interoceptive exposure, lifestyle regularization.
