A panic attack is a sudden surge of intense fear with strong physical symptoms, such as a pounding heart, shortness of breath, or dizziness, that arrives abruptly and usually passes within minutes. An “anxiety attack” is an everyday phrase for anxiety that builds gradually in response to a worry or stressor. The clearest difference is speed: panic arrives all at once, and anxiety builds. Only one of the two is a clinical term. The diagnostic manual clinicians use defines a panic attack and does not define an anxiety attack at all.
Both are common. An estimated 2.7% of U.S. adults have panic disorder in a given year, according to the National Institute of Mental Health, drawing on the National Comorbidity Survey Replication (2001–2003). More broadly, 18.2% of U.S. adults reported symptoms of anxiety in the previous two weeks in 2022, up from 15.6% in 2019 (CDC National Center for Health Statistics, 2024).
One caveat before anything else. Chest pain, trouble breathing, or symptoms you have never had before deserve medical attention. If you think you may be having a heart attack, call 911. A physician can rule out other causes, and that matters before assuming it is panic.
The difference at a glance
| Panic attack | “Anxiety attack” | |
|---|---|---|
| Clinical term | Yes, defined in the DSM-5-TR | No formal definition |
| Onset | Abrupt, often without warning | Gradual, builds over hours or days |
| Trigger | Sometimes none at all | Usually a specific worry or stressor |
| Intensity | Severe, can feel life-threatening | Mild to strong, rarely overwhelming |
| Duration | Usually minutes | Hours, days, or longer |
| Central fear | “Something is terribly wrong right now” | “Something is going to go wrong” |
What a panic attack is
A panic attack is a recognized clinical event. By definition it involves four or more symptoms from a specific list, which includes:
- A pounding or racing heart
- Sweating, chills, or trembling
- Shortness of breath or a choking sensation
- Chest pain or tightness
- Dizziness, weakness, or tingling in the hands
- Nausea or stomach pain
- A feeling of being out of control
- A fear of dying or of impending doom
The National Institute of Mental Health describes a panic attack as a sudden wave of fear that can come “even when there is no clear danger or trigger.” It can last from a few minutes to an hour, and most last about 15 to 20 minutes.
Having a panic attack does not mean you have panic disorder. Panic disorder is diagnosed when attacks are recurrent and unexpected, and are followed by at least a month of worry about having another one or of changing your behavior to avoid one.
What people mean by an anxiety attack
When someone says they had an anxiety attack, they usually mean a stretch of rising worry, tension, and unease that built up around something specific: a deadline, a conflict, a health scare, a decision. The body takes part, with a tight chest, a restless stomach, and trouble sleeping, but the symptoms climb slowly and tend to stay below the intensity of panic.
Because the phrase has no clinical definition, it covers a wide range. For one person it means a difficult afternoon. For another it describes what a clinician would recognize as generalized anxiety. The experience is real either way. The label is simply informal.
How to tell which one you are having
- How fast did it start? If it went from calm to overwhelming in a few minutes, that points to panic. If it crept up over hours or days, that points to anxiety.
- Was there a clear cause? Anxiety usually attaches to something you can name. Panic often arrives with no obvious cause, sometimes in a calm moment or during sleep.
- How intense were the physical symptoms? Panic produces symptoms strong enough that many people believe they are having a heart attack. Anxiety is uncomfortable but usually lets you keep functioning.
- How long did it last? Panic is brief and passes on its own. Anxiety lingers, and it often eases only when the situation behind it changes.
- What were you afraid of? In panic, the fear is about what is happening in your body right now. In anxiety, the fear is about something that might happen later.
If you are in the middle of one now, the steps in how to stop a panic attack apply to both.
When one turns into the other
The two are different, and they are also connected. A long build of anxiety can end in a panic attack, particularly once you begin to fear the sensations themselves. A racing heart becomes a sign of danger, the fear makes the heart race faster, and the loop closes.
This is also how panic becomes a pattern. After one attack, many people start watching their bodies for the next one, and that watchfulness can produce the very sensations they are afraid of. If you find yourself scanning for symptoms or fearing an illness no test has found, health anxiety may be part of the picture.
Why the difference matters
The distinction matters because the two respond to different work.
Panic is treated by changing your relationship to the physical sensations. Cognitive behavioral therapy and exposure-based approaches, both named by the National Institute of Mental Health as treatments for panic disorder, teach the nervous system that a racing heart is uncomfortable and not dangerous.
A slow build of anxiety is treated by working on the worry itself: the thoughts that drive it, the situations that feed it, and the habits, such as avoidance and poor sleep, that keep it going. Our post on why you might feel anxious for no reason covers the common drivers.
As Jack Foley, LMFT, puts it:
“People often arrive apologizing for not knowing which one they have. It matters less than they think. What matters is noticing whether the fear is about what your body is doing right now or about what might happen next, because those two fears are worked with differently.”
Medication can be part of care for some people. That is a question for a prescriber, and our clinicians coordinate with psychiatry when it comes up.
When to get help
Consider talking with a licensed clinician if the episodes keep returning, if you have started avoiding places or situations because of them, or if worry about the next one is shaping your choices. You do not need to know which kind you are having before you call. Sorting that out is part of a first conversation.
Our clinicians work with panic attacks and anxiety in person in the South Bay and virtually across California. A free 15-minute consultation is a low-pressure way to talk it through.
