What is a Panic Attack?
A panic attack is a discrete episode of intense fear or discomfort that reaches peak intensity within minutes and involves at least four physical and psychological symptoms. DSM-5 defines thirteen possible symptoms including: palpitations or accelerated heart rate; sweating; trembling; shortness of breath or feeling smothered; chest pain; nausea; dizziness or faintness; derealisation (feelings of unreality) or depersonalisation (being detached from yourself); fear of losing control or "going crazy"; fear of dying; numbness or tingling; chills or hot flushes.
The key feature of a panic attack is its sudden onset and rapid peak — typically within 10 minutes. Panic attacks can occur "out of the blue" (unexpected) or in response to specific triggers (expected or situationally predisposed). The unexpected panic attack — with no identifiable trigger — is the hallmark of panic disorder.
What is an Anxiety Attack?
"Anxiety attack" is not a clinical diagnostic term — it does not appear in DSM-5 or ICD-11. It is a colloquial term typically used to describe a period of intense anxiety that builds gradually in response to a stressful situation. The symptoms overlap with panic — worry, tension, restlessness, physical arousal — but the onset is slower, the duration is longer, and the peak intensity is typically lower than a panic attack.
What people call an "anxiety attack" often represents an acute exacerbation of generalised anxiety or situational anxiety — a spike in response to a stressor that resolves when the stressor resolves. It is real and distressing but mechanistically different from a panic attack.
Key Differences at a Glance
| Feature | Panic Attack | Anxiety Attack |
|---|---|---|
| Onset | Sudden, peaks within minutes | Gradual build-up |
| Duration | Minutes (typically 5–30 min) | Hours or longer |
| Trigger | May have no identifiable trigger | Usually linked to a stressor |
| Clinical term | Yes — DSM-5 defined | No — colloquial term |
| Key fear | Dying, losing control, going mad | Worry about stressor |
Why the Distinction Matters for Treatment
Panic disorder (recurrent unexpected panic attacks plus persistent concern about future attacks) has a specific, highly effective treatment: CBT with interoceptive exposure — deliberately inducing panic-like sensations to demonstrate they are harmless — plus in-vivo exposure to avoided situations. General anxiety (GAD) is treated with CBT focused on worry and uncertainty intolerance. Getting the distinction right means getting the treatment right.
What to Do During a Panic Attack
Counterintuitively, the most effective response to a panic attack is to allow it to peak and pass without fighting it. Fighting panic — trying to stop it, escape, or control it — paradoxically intensifies it. Controlled breathing (4 in, 6 out) can moderate the physiological response. Reminding yourself "this is a panic attack — it is unpleasant but not dangerous and it will pass" reduces catastrophic interpretation and accelerates resolution.
Frequently Asked Questions
Yes — chest pain, palpitations, and breathlessness in a panic attack closely mimic cardiac symptoms. If you are unsure whether you are experiencing a panic attack or a cardiac event — particularly if it is a first episode or you have cardiac risk factors — seek medical assessment. A GP or A&E can differentiate between the two.
No. Despite their intensity, panic attacks are physiologically safe. They involve normal stress responses (adrenaline, hyperventilation, increased heart rate) that are unpleasant but not dangerous. The physical symptoms feel alarming precisely because the brain is interpreting them as signs of danger — the core cognitive error in panic disorder.
The Cognitive Model of Panic
Clark's cognitive model of panic — one of the most robust and clinically productive models in CBT — explains panic disorder as a self-reinforcing cycle driven by catastrophic misinterpretation of normal physiological sensations. The sequence: anxiety or excitement produces normal physical sensations (heart rate elevation, breathlessness, lightheadedness). These sensations are noticed and catastrophically misinterpreted ("I am having a heart attack"; "I am about to faint"; "I am losing control of my mind"). The catastrophic interpretation generates intense anxiety. The intense anxiety amplifies the physical sensations. The amplified sensations are interpreted as further evidence that something catastrophic is happening. The cycle escalates to full panic within minutes.
This model explains why panic attacks can occur "out of the blue" — they can be triggered by any physical sensation, including those from exercise, caffeine, heat, or even the physical symptoms of anxiety about something unrelated. It also explains why CBT — which directly targets the catastrophic interpretation — is so effective: removing the catastrophic misinterpretation removes the amplification loop, and the sensations remain manageable rather than escalating to panic.
What Maintains Panic Disorder
Not everyone who has a panic attack develops panic disorder. What turns an isolated panic attack into a disorder is the development of anticipatory anxiety — persistent worry about having further panic attacks — and the behavioural changes that follow. Avoiding situations associated with panic attacks (public transport, supermarkets, exercise), using safety behaviours (always carrying escape routes, always being accompanied), and monitoring internal sensations hypervigilantly all maintain and expand the panic disorder by preventing the disconfirmatory learning that panic attacks are not dangerous and are survivable without escape.
CBT for Panic Disorder: What to Expect
CBT for panic disorder is one of the most effective psychological treatments available — NICE recommends 7-14 sessions and clinical trials show response rates of 70-90%. The treatment includes: psychoeducation about the panic cycle; breathing retraining; cognitive restructuring of catastrophic interpretations of physical sensations; interoceptive exposure (deliberately inducing panic-like sensations through exercise, spinning, or hyperventilation to demonstrate their harmlessness); in-vivo exposure to avoided situations; and elimination of safety behaviours. The combination of these components produces comprehensive, durable recovery for the majority of people who complete the full course.

More Frequently Asked Questions
No. Despite their intensity, panic attacks are physiologically safe. They involve the normal stress response — adrenaline, elevated heart rate, hyperventilation — which is unpleasant but not medically dangerous in a physically healthy person. If you have cardiac risk factors or are unsure whether symptoms are cardiac rather than panic, medical assessment is appropriate to rule out physical causes.
If it is your first episode and you cannot distinguish it from a cardiac event, attending A&E is reasonable. Once panic disorder is established and you are confident the sensations are not cardiac, attending A&E during panic attacks is generally counterproductive — it reinforces the belief that the panic represents a medical emergency and the safety-seeking behaviour maintains the disorder.
Yes. Multiple RCTs confirm equivalent outcomes for online CBT for panic disorder compared with in-person delivery. Interoceptive exposure exercises — inducing panic sensations deliberately — can be conducted independently by the client between sessions, making online delivery well-suited to this treatment approach.
