A panic attack has a clinical definition; an anxiety attack has no separate one. The DSM-5-TR, the diagnostic handbook of the American Psychiatric Association, describes a panic attack as an abrupt surge of intense fear or discomfort that peaks within minutes and brings at least 4 of 13 listed symptoms, from a pounding heart to a fear of dying.¹

The American Psychiatric Association’s summary of the DSM-5-TR lists panic disorder among the anxiety disorders, and nothing called an anxiety attack.² So in the panic attack vs anxiety attack question, the label matters less than the shape of what happened. Three questions describe any episode: how fast it peaked, how long it lasted, and whether it keeps coming back. One rule comes before all three: chest pain or trouble breathing calls for emergency help first, because only medical tests can rule out the heart.

What the DSM-5-TR counts as a panic attack

A panic attack, in the DSM-5-TR, is a sudden wave of intense fear or discomfort that reaches its peak within minutes and brings four or more symptoms from a fixed list of 13. The list mixes the body and the mind: a racing or pounding heart, sweating, trembling, shortness of breath, a choking feeling, chest pain, nausea, dizziness, chills or hot flashes, numbness or tingling, feeling detached or unreal, fear of losing control and fear of dying.¹

Why define it so tightly? A count of symptoms and a time shape give clinicians something they can recognize and compare across patients. The time shape matters most: the attack climbs fast and then subsides, instead of hanging on at a steady pitch. That shape is the first thing to check against your own experience.

Anxiety attack has no such entry. The American Psychological Association’s dictionary sends readers from “anxiety attack” straight to panic attack, which it says is also called an anxiety attack.³ MedlinePlus, the consumer health site of the US National Library of Medicine, lists anxiety attacks among the alternative names for panic disorder.⁴

Myth

An anxiety attack is a milder, separate diagnosis from a panic attack.

Fact

The American Psychiatric Association's list of DSM-5-TR anxiety disorders has no anxiety attack. US reference works use the phrase as another name for a panic attack; occasional anxiety is normal and becomes a disorder only when it is out of proportion, persistent and disruptive.

Because the phrase has no fixed meaning, two people can use it for very different days. One colleague says she had an anxiety attack before a presentation and means ten minutes of a hammering heart, shaking hands and a sense of doom. Another says the same thing and means an afternoon of dread and a tight chest that never quite peaked. The first matches the panic attack definition; the second sounds more like anxiety, which builds around a worry about what might happen and tends to linger rather than spike. To understand your own episode, or explain it to a doctor, describe its shape rather than picking a label.

Panic attack vs anxiety attack: how the experiences compare

The clearest comparison sets a panic attack beside anxiety, as clinicians use the word, and beside panic disorder, the condition built from repeated attacks. Underneath it sits a line the American Psychiatric Association draws between fear, a response to an immediate threat, and anxiety, the anticipation of a future concern.² A panic attack is an episode of intense fear that arrives fast; anxiety is tied to something that has not happened yet, and in an anxiety disorder it can last for months or keep coming back. In the table, each row’s sources sit at its end.

Read across the rows and three verdicts follow. If the thing you call an anxiety attack matches the first column, a clinician would call it a panic attack, and a single surge, however frightening, is not yet a disorder. Days of dread and tension without a sharp peak point toward anxiety rather than panic; if you are unsure where ordinary pressure ends, start with how stress differs from anxiety. And attacks that keep coming, with you arranging life around them, fit the pattern of panic disorder and are worth a doctor’s time.

Many people have a panic attack; far fewer develop panic disorder

A panic attack is far more common than panic disorder, and most people who have had one have never had the disorder, according to a 2016 analysis of the World Health Organization’s World Mental Health Surveys, which asked the question in 25 countries.⁷

The study

Moderate evidence

Common attacks, rarer disorder: household surveys in 25 countries, 2016

De Jonge and colleagues pooled household surveys in which trained lay interviewers asked adults about their mental health history using a standard diagnostic interview, applying DSM-5 definitions. About 13 percent had had at least one panic attack in their lives. Of those, only about 1 in 8 met the criteria for panic disorder, so about 2 percent of all adults had had the disorder. Two-thirds of people with attacks but no disorder had had more than one. Repeated attacks were linked to the later onset of other mental disorders; single attacks generally were not.⁷

A first panic attack, in other words, puts you in large company rather than in a diagnosis. The survey’s main weakness is memory. Everything was recalled in a single interview, and the authors expect that recall probably led to underestimates, particularly for panic attacks, which were probed less thoroughly than full disorders. The link between repeated attacks and later disorders is an association from surveys, not proof that the attacks cause them.⁷

A separate US survey used older criteria. The National Comorbidity Survey Replication, a nationally representative US survey from 2001 to 2003 that applied DSM-IV, found that about 3 in 100 adults had panic disorder in the past year, with past-year rates more than twice as high in women as in men.⁸ Because the surveys, criteria and years differ, read each set of figures on its own terms rather than comparing them directly.

The practical lesson is to watch the pattern, not the single event. One attack after a hard week deserves attention, and chest pain during any attack calls for emergency help at the time, as the next section explains. Attacks that return, or a growing habit of avoiding the places where they happened, are the pattern that the definition of panic disorder in the table describes.

Why a panic attack can feel like a heart attack

Panic attacks and heart attacks share several symptoms, and NIMH notes that panic attacks often bring physical symptoms that might feel like a heart attack, such as a rapid heart rate.⁶ Chest pain, shortness of breath, sweating, nausea, a racing heart and light-headedness appear on MedlinePlus’s list of heart attack symptoms as well as on the panic attack list, and MedlinePlus counts anxiety itself among heart attack symptoms; some people, women among them, may have little or no chest pain during a heart attack.⁹

1. Listed for panic attacks: fear of losing control or of dying, feeling detached or unreal, numbness or tingling
2. On both lists: chest pain or discomfort, shortness of breath, sweating, nausea, a racing heart, light-headedness; MedlinePlus also lists anxiety itself among heart attack symptoms
3. Listed for heart attacks: pain moving from the chest to the arms, shoulder, neck, jaw, belly area or back; cough
4. What tells them apart: medical tests such as an ECG and blood tests, not how the symptoms feel

The overlap works in both directions, and neither can be sorted out by feel. The NHS says finding out whether someone is having a heart attack takes tests, including an electrocardiogram (ECG) and blood tests.¹⁰ Heart rhythm problems can be mistaken for panic too. In a small 2025 records review and phone survey at one Saudi hospital, 20 of the 47 responding patients with supraventricular tachycardia, a fast heart rhythm, had first been diagnosed with anxiety or panic attacks; an ECG taken during an episode, with further tests, finally told the two apart. One center is thin evidence, but its point matches the NHS’s.¹¹

Even the panic guidance hedges. The NHS says panic attacks are not dangerous, then warns that most of their symptoms can also be symptoms of other conditions, so you may not always be having a panic attack.⁵ England’s NICE guideline on panic disorder, in a recommendation dating from 2004, expects a person who arrives at A&E with a panic attack to have the minimum investigations needed to exclude acute physical problems, then to be referred to primary care with written information about panic attacks. NICE reviewed the guideline in September 2026 and concluded that it needs an update, which has not yet started.¹²

Take an ordinary evening at home. Someone who has had panic attacks for years feels a familiar tightness in the chest and a racing heart. The history makes panic a tempting explanation, but the NHS’s warning still applies, and so does MedlinePlus’s advice to call 911 or the local emergency number right away rather than wait. Calling for help is not an overreaction; it is the only way to get the tests that answer the question.

What panic disorder is, and how it is treated

Panic disorder is diagnosed when a person has recurrent, unexpected panic attacks and spends at least a month worrying about more attacks, fearing what they mean, or changing their behavior to avoid them, according to NIMH. A provider may do a physical exam to make sure an unrelated physical problem is not causing the symptoms. The main treatments are talk therapy, medication or both, NIMH says, and it describes cognitive behavioral therapycognitive behavioral therapy: A structured talking therapy that works on the links between thoughts, feelings and behavior, usually over a set number of sessions with practice between them. It is given by a trained therapist or through guided programs, and versions exist for specific problems.Full entry in the glossary as well studied and the gold-standard choice of psychotherapy; it names exposure to the body sensations of panic as one CBT technique.⁶

The definition turns on more than the attacks: it also asks how far life has bent around them. Picture someone who has one attack on a crowded train, starts taking the bus instead, and then begins leaving meetings early in case another one comes. The attacks may be rare, but the worry and the detours are exactly what the second half of the definition describes.

The NHS calls panic disorder treatable, and in England people can refer themselves to an NHS talking therapies service for CBT-based treatment.⁵ If you notice yourself planning days around the fear of an attack, that is a good reason to book an appointment. What to do in the middle of an attack, and how medicines compare, are topics for separate guides and for a conversation with your doctor.

Getting help: what needs a call now, and what can wait for a GP

Chest pain, trouble breathing or thoughts of suicide need emergency help now; panic attacks that recur or disrupt daily life need a doctor soon; and occasional, manageable episodes can wait for your next appointment. We grouped the advice into these three tiers ourselves; each line credits the US or UK body that gives it.

• Now. In the US, MedlinePlus advises calling 911 or the local emergency number right away for heart attack symptoms, and not driving yourself to the hospital; the pain can move from the chest to the arms, shoulder, neck, jaw, belly area or back.⁹ In the UK, the NHS tells people to ring 999 for severe difficulty breathing or for chest pain that feels tight or squeezing or that moves into the arms, neck or jaw, and not to drive yourself to A&E.¹⁰ For thoughts of suicide, MedlinePlus points to 988, the Suicide and Crisis Lifeline, where a call or text reaches free, confidential support at any hour; its alternative is 911 or the local emergency number, and outside the US and UK that local number is the route to use.⁴ The NHS page on urgent mental health help advises 999, or A&E, when someone’s life is at risk or you do not feel you can keep yourself or someone else safe, and gives the Samaritans number, 116 123, for anyone who needs to talk.¹³
• Soon. In the US, MedlinePlus advises contacting your provider if panic attacks are interfering with your work, relationships or self-esteem.⁴ A GP appointment is the NHS’s advice for anyone who has had symptoms of panic disorder, and the GP may examine you to rule out other conditions.⁵ For urgent mental health needs short of an emergency, the NHS in England directs people to NHS 111, by phone or online, which has a mental health option.¹³
• Routine. An occasional anxious spell, without chest pain or trouble breathing, that passes and does not change how you live is worth mentioning at your next check-up, and more so if it starts coming back more often. The notes below make that conversation quicker, whichever tier you are in.

The bottom line

“Anxiety attack” is not a diagnosis, and in US reference works it means a panic attack. What matters is the shape: a surge that peaks within minutes is a panic attack, and a single one is common and not a disorder. Repeated attacks with worry or avoidance are worth a doctor’s time, because panic disorder is treatable. Chest pain or trouble breathing is always a reason to call for emergency help, because only tests can rule out the heart.
