Two phrases, one confusing overlap
People use "panic attack" and "anxiety attack" interchangeably, and both can describe a frightening experience. But only one of them is a clinical term. Cleveland Clinic explains that the DSM-5-TR, the manual clinicians use to diagnose mental health conditions, defines panic attacks but does not recognize or define an "anxiety attack." In most cases, it says, "anxiety attack" is used as an everyday term for a panic attack.
That does not mean what you felt was not real. It means the words matter when you describe it to a doctor or therapist. Telling them what happened in your body, how fast it came on and how long it lasted will be more useful than either label.
What a panic attack is
Cleveland Clinic describes a panic attack as sudden, temporary fear with strong physical reactions to an ordinary, nonthreatening situation. Symptoms usually peak within 10 minutes, and most attacks last 5 to 20 minutes, although some people report attacks lasting up to an hour. By definition, a panic attack involves four or more symptoms such as:
- A racing or pounding heart
- Chest pain or discomfort
- Sweating, chills or feeling overheated
- Trembling or shaking
- A choking or smothering feeling, or trouble breathing
- Dizziness or nausea
- Numbness or tingling
- A sense that things are not real, or that you are detached from yourself
- Fear of losing control or of dying
Panic attacks can feel like a heart attack, which is why many people end up in an emergency department the first time. NIMH notes that while they are distressing, panic attacks themselves are not life-threatening and the physical symptoms usually resolve with time.
They are also common. Cleveland Clinic reports that up to 11% of people in the United States have a panic attack each year, and that panic attacks can happen alongside phobias, mood disorders, trauma-related conditions and other anxiety disorders, not only panic disorder.
What people usually mean by an anxiety attack
When people say "anxiety attack," they often mean something that builds. Cleveland Clinic describes the main difference this way: anxiety is often triggered by a specific stressor and can build gradually, while panic attacks typically arrive suddenly and unexpectedly. Anxiety can bring a racing heart or knots in the stomach, but those symptoms are generally less intense and last longer than a panic attack.
A typical example: the evening before a performance review, worry climbs for hours. Your shoulders tighten, your stomach churns, you cannot focus on dinner, and sleep comes late. That is real and exhausting, but it is a slow rise, not a sudden spike. Compare a Tuesday afternoon at Somerset Collection when, out of nowhere, your heart pounds, your hands tingle and you are sure you need to get out right now, and ten minutes later it fades. The second pattern matches a panic attack.
A side-by-side comparison
- Onset: panic attacks come on suddenly, sometimes with no clear trigger; heightened anxiety usually builds around something specific.
- Peak: panic peaks within minutes; anxiety can simmer for hours or days.
- Intensity: panic is very intense and brief; anxiety is usually less intense and longer lasting.
- Fear content: panic often brings fear of dying, losing control or "going crazy"; anxiety tends to center on a real-life worry.
- Clinical status: a panic attack is a defined term; "anxiety attack" is not.
Real life is messier than a table. Sustained anxiety can tip into a panic attack, and people who have had one panic attack sometimes start anxiously watching for the next.
Rule out a medical cause first
The symptoms of a panic attack overlap with heart, thyroid and breathing problems. Cleveland Clinic advises seeking emergency care if you have chest pain, trouble breathing or lose consciousness, and notes that providers may test for heart disease, thyroid disease and respiratory problems before attributing symptoms to panic. The NHS makes the same point from the other direction: most panic symptoms can also be signs of other conditions, so not every episode is a panic attack. If you are not sure, get checked. Being told your heart is fine is useful information, not a waste of anyone's time.
In the moment
Cleveland Clinic suggests labeling what is happening ("This is a panic attack; it is uncomfortable, and it will end"), slowing your breathing, and using your other senses to steady yourself, such as washing your face or holding something cold. The NHS adds staying where you are if you can and reminding yourself the attack will pass. How to Get Through a Panic Attack walks through these steps in more detail.
Afterward, it helps to jot down when and where it happened, how long it lasted and what came before it. Cleveland Clinic notes that tracking attacks can reveal triggers and show you whether things are improving.
When it may be more than an occasional attack
NIMH is clear that an isolated panic attack is not a mental disorder. A pattern is different: repeated unexpected attacks, a month or more of worrying about the next one, or rearranging your life to avoid places where attacks happened. That pattern is what clinicians call panic disorder, explained in What Is Panic Disorder?.
Long, building anxiety deserves attention too, especially if it is affecting your sleep, work or relationships. In anxiety therapy, Dr. Lehmann helps adults understand what sets off both kinds of episodes, practice ways to ride them out, and look at the history and pressures that keep the alarm system so sensitive.
