Panic attacks are acute, intense surges of sympathetic nervous system arousal that peak within minutes, producing terrifying sensations such as palpitations, dyspnea, dizzy spells, and feelings of imminent death or losing control. In David M. Clark’s cognitive model of panic disorder (1986), panic is maintained by a catastrophic misinterpretation of harmless internal bodily sensations (such as interpreting an innocent tachycardic flutter as an impending myocardial infarction). When individuals develop persistent anticipatory dread of future attacks and engage in maladaptive behavioral alterations, a clinical diagnosis of Panic Disorder is established. The Panic Attacks and Panic Disorder Psychoeducation Module delivers 21 interactive structured video lessons detailing panic physiology, interoceptive conditioning, and exposure protocols.

The Physiology of Panic: Fight-or-Flight False Alarms
A panic attack represents an inappropriate firing of the brain’s survival circuitry—specifically the amygdala triggering the sympathetic adrenomedullary (SAM) axis in the absence of objective environmental threat. Hyperventilation alters blood pH (respiratory alkalosis), inducing cerebral vasoconstriction that produces dizziness, paresthesia (tingling in fingers and lips), and derealization. While profoundly distressing, panic surges are biologically self-limiting due to parasympathetic negative feedback loops.
Clark’s Cognitive Model: The Panic Cycle
- Internal / External Trigger: Normal somatic fluctuation, caffeine intake, fatigue, or stressful setting.
- Perceived Threat: Heightened sensory vigilance towards cardiac, respiratory, or vestibular sensations.
- Apprehension & Anxiety: Anticipatory dread producing further sympathetic adrenaline release.
- Somatic Amplification: Acceleration of heart rate, shallow breathing, chest tightness, or lightheadedness.
- Catastrophic Misinterpretation: The conviction: “I am having a heart attack,” “I am going to faint,” or “I am losing my mind.” This instantly retriggers the amygdala, generating a crescendo of panic.
Interoceptive Exposure: Retraining the Nervous System
The clinical gold-standard intervention within Cognitive Behavioural Therapy (CBT) is Interoceptive Exposure (IE). Under therapeutic guidance, individuals deliberately recreate panic-like bodily sensations (e.g., hyperventilating for 60 seconds, spinning in an office chair, or breathing through a narrow straw) without using safety behaviours (such as clutching water bottles, sitting near exits, or checking pulses). Repeated unreinforced exposure breaks the conditioned terror association, proving somatic sensations are harmless.
