What is a panic attack?
A panic attack is a sudden surge of intense fear or discomfort that peaks within minutes. Physical symptoms are intense and alarming: racing or pounding heart, shortness of breath, chest pain, dizziness, tingling sensations, sweating, and an overwhelming sense of dread or unreality. The experience is terrifying — many people believe they are having a heart attack or dying.
The critical thing to understand: panic attacks are not medically dangerous. The physical symptoms, though frightening, are produced by the body's normal stress response — adrenaline and the fight-or-flight system activated incorrectly. They cannot cause a heart attack, stop your breathing, or cause you to lose consciousness.
Panic disorder vs isolated panic attacks
Many people experience occasional panic attacks — they are extremely common. Panic disorder involves recurring unexpected panic attacks AND persistent concern about future attacks or significant behavioral changes to avoid them. The fear of the next panic attack, and the avoidance that follows, can become more disabling than the attacks themselves.
Agoraphobia
When panic attacks lead to avoidance of situations where escape might be difficult or embarrassing — crowded places, public transportation, being outside alone — agoraphobia develops. Agoraphobia can become severely limiting, in extreme cases preventing people from leaving their home. It is maintained and worsened by avoidance, making exposure-based treatment essential.
Treatment: CBT with interoceptive exposure
Cognitive Behavioral Therapy is the most effective treatment for panic disorder, with response rates of 70-90%. A key component is interoceptive exposure — deliberately inducing the physical sensations of panic (through spinning, breathing through a coffee straw, running in place) in a controlled way to reduce the fear of those sensations. This is counterintuitive but highly effective.
SSRIs and SNRIs are also effective for panic disorder and are often combined with CBT. Benzodiazepines provide rapid symptom relief but should be used only short-term — they can worsen long-term outcomes by preventing the learning that panic sensations are not dangerous.
Seeking medical evaluation for a first panic attack is reasonable to rule out cardiac causes. But once medical causes are excluded, pursuing CBT rather than repeated medical testing is the appropriate next step. Repeated cardiac testing without positive findings can maintain health anxiety.
