Panic Attacks and Panic Disorder
A panic attack is not a heart attack, but it often feels like one. This guide explains what panic attacks actually are, how long they last, what they do to the body, and how panic disorder is treated.

The first panic attack almost always goes to the emergency room.
Chest pain. Pounding heart. Shortness of breath. The feeling that you’re about to die. Most people having their first panic attack are convinced they’re having a cardiac event. They end up in the ER, get an EKG, get blood work, and are told their heart is fine. Relief, and then confusion. What was that?
What it was is panic. And once you know the pattern, it becomes much less mysterious and much more treatable.
This page walks through what a panic attack actually is, the physical symptoms that show up, how it differs from a heart attack, nervous breakdown, or general anxiety, and how panic disorder is evaluated and treated.
What Is a Panic Attack?
A panic attack is a sudden surge of intense fear or discomfort that peaks within minutes and triggers a cascade of physical symptoms. Racing or pounding heart. Sweating. Trembling. Shortness of breath. A feeling of choking. Chest pain or tightness. Nausea. Dizziness or lightheadedness. Chills or hot flashes. Numbness or tingling. A sense of unreality or detachment from yourself. A fear of losing control or dying.
Not everyone experiences every symptom. What distinguishes panic from general anxiety is the intensity and the speed. Panic attacks typically peak within 10 minutes and then gradually subside, while general anxiety can persist low-grade for hours or days.
Anxiety Attack vs Panic Attack vs Nervous Breakdown
The terms get used interchangeably in everyday conversation but mean different things clinically.
Panic attack is a specific clinical term for a discrete episode of intense fear with the sudden-onset physical symptoms described above. Peaks quickly. Subsides within 20 to 30 minutes usually.
Anxiety attack is not a formal clinical diagnosis. It’s a colloquial term people use for acute anxiety episodes that may not meet the criteria for a full panic attack (less intense, slower onset, longer duration). Clinicians generally use “panic attack” for the clinical event and “anxiety episode” or “acute anxiety” for the broader pattern.
Panic attack vs anxiety attack vs mental breakdown. A “mental breakdown” or “nervous breakdown” is an informal term, not a diagnosis. It usually describes a period when someone can no longer function due to overwhelming mental health symptoms, which could involve panic, major depression, psychosis, or acute stress. The term is vague, but the experience behind it is real and warrants evaluation.
Anxiety attack vs nervous breakdown. An anxiety attack is a discrete episode. A “nervous breakdown” describes a sustained period of being unable to cope. Someone in the midst of what they’d call a nervous breakdown may have multiple anxiety or panic attacks, but it’s the broader loss of functioning that the term is pointing to.
What Panic Attacks Do to the Body
Can an anxiety attack make you pass out? Rarely, but yes. The more common physical experience during panic is feeling like you might faint without actually fainting. True fainting during panic is uncommon, because panic tends to raise blood pressure rather than drop it. When fainting does occur, it’s usually from hyperventilation (breathing too fast and off-gassing too much carbon dioxide).
Can an anxiety attack cause you to faint? Yes, but it’s uncommon. If you repeatedly faint during anxiety or panic episodes, medical evaluation matters to rule out blood pressure drops, cardiac causes, or other conditions that can masquerade as panic.
Can you pass out from an anxiety attack? Most people who feel like they’re about to pass out during panic don’t actually lose consciousness. The sensation of imminent fainting is itself a symptom of hyperventilation and blood flow changes, not a reliable indicator that you’ll actually go down.
Can an anxiety attack cause a heart attack? A panic attack is not a heart attack, but the question of whether it can cause one is reasonable. For otherwise healthy people, a panic attack itself does not cause a heart attack. For people with significant pre-existing cardiac disease, extreme physiological stress can be a contributor. The much more common confusion is panic being mistaken for a heart attack, which is why cardiac evaluation at the first panic attack is standard.
Difference between a heart attack and anxiety attack. Heart attacks more often involve pressure or squeezing chest pain that radiates to the arm, jaw, or back, lasting longer than 20 minutes, often with nausea, sweating, and shortness of breath that don’t resolve. Panic attacks typically involve sharp or stabbing chest pain, peak and resolve within minutes, and include intense fear or the feeling of impending doom. Any new chest pain should be evaluated medically before it’s attributed to panic.
Can hypertension cause anxiety attacks? High blood pressure itself doesn’t typically trigger panic attacks, but the physical sensations of elevated blood pressure (head pressure, racing heart, lightheadedness) can trigger anxiety in people who are monitoring their readings closely. Blood pressure medications, withdrawal from caffeine or alcohol, and thyroid problems can all produce panic-like symptoms and should be ruled out during evaluation.
Heart rate during anxiety attack. Heart rate commonly climbs to 120 to 150 beats per minute during panic and can occasionally go higher. This is why panic is frequently mistaken for cardiac events. The sustained elevation isn’t dangerous in healthy individuals, but it’s exhausting.
Blood pressure during anxiety attack. Blood pressure typically rises during panic, not falls. Readings taken during or shortly after a panic attack will usually be elevated and aren’t a reliable measure of baseline blood pressure.
Numb hands during anxiety attack. Tingling and numbness in the hands, feet, and around the mouth during panic is extremely common and is driven by hyperventilation. It’s not dangerous and resolves as breathing returns to baseline.
How Long Do Panic Attacks Last?
Anxiety attack duration varies, but most panic attacks peak within 10 minutes and resolve within 20 to 30 minutes. The intense physical symptoms subside first, followed by a longer tail of emotional and physical aftermath.
How long can an anxiety attack last? Individual panic attacks rarely last more than 30 to 45 minutes at peak intensity. What people often describe as an anxiety attack lasting hours is usually a panic attack followed by sustained anxiety and physiological hyperarousal, rather than the acute panic itself persisting that long.
Can an anxiety attack last for days? True panic attacks do not last for days. What can last for days is a state of heightened anxiety, anticipatory fear of the next attack, physical exhaustion from the original attack, and repeated lower-grade panic waves. This pattern is what panic disorder looks like when untreated.
Anxiety attack length is also affected by what happens during and after. Fighting the panic, trying to stop it by force of will, or catastrophizing about the symptoms tends to prolong it. Letting it run its course while staying safe tends to shorten it.
The Anxiety Attack Hangover
Panic attacks are physiologically expensive. After the acute event ends, the body is depleted.
Anxiety attack hangover. The common experience after a panic attack includes intense fatigue, emotional flatness or weepiness, muscle soreness (especially in the chest, jaw, and shoulders), headache, and a sense of being wrung out. This “hangover” can last hours or into the next day.
Fatigue after anxiety attack. Panic triggers a full sympathetic nervous system response (fight, flight, freeze). When that system finally disengages, the rebound is exhaustion. This is biologically normal.
Exhausted after anxiety attack. Tired after anxiety attack. Sleepy after anxiety attack. All common. Panic burns through significant energy, and the body’s recovery response often triggers profound sleepiness as part of the parasympathetic rebound.
Post anxiety attack fatigue that lasts more than a day or so may indicate that panic episodes are occurring back-to-back, or that a broader anxiety state is persisting between clear panic events. This pattern is worth discussing with a psychiatrist.
Silent Anxiety Attacks
Silent anxiety attack is a term used for panic episodes that happen without the outwardly visible signs (visible shaking, obvious gasping, dramatic collapse). The experience is still intense internally, but the person is able to function externally during it.
Silent anxiety attacks symptoms tend to be more internal: racing heart felt in the chest, waves of dread, a sense of disconnection from the room, internal trembling, and tight restriction of breath rather than obvious gasping. Silent panic often happens at work, in meetings, during conversations, or in social settings where the person feels they can’t show what’s happening.
Silent panic is just as clinically significant as visible panic and responds to the same treatment.
Panic Attacks in Specific Situations
Anxiety attack during sleep. Nocturnal panic attacks wake people from sleep, typically from non-REM sleep, with the full cascade of panic symptoms. They’re terrifying because there’s no warning or trigger. Nocturnal panic often responds well to treatment and is not a sign of more severe illness.
Anxiety attack at night. Middle of night anxiety attack. The 2 a.m. or 3 a.m. panic attack is a recognized pattern. Cortisol patterns, reduced cognitive defenses during sleep, and the absence of daytime distractions all contribute.
Anxiety attack on airplane. Flying is a common trigger for panic in people with or without pre-existing panic disorder. The combination of physical confinement, cabin pressure changes, and inability to leave the situation activates many of the mechanisms underlying panic. Beta blockers and targeted treatment for flight-specific phobia can be effective.
Anxiety attack at work. Work-related panic often shows up as silent panic rather than visible collapse. The work environment typically forces people to mask symptoms, which itself can prolong and worsen episodes.
Anxiety attack perimenopause. Hormonal shifts during perimenopause can trigger new-onset panic or worsen existing panic patterns in many women. This is an area where coordination between psychiatric care and gynecologic or endocrine care often matters.
Throwing up from anxiety attack. Vomiting during panic is more common than many realize, particularly when nausea is a prominent symptom of the attack. It’s driven by vagus nerve activation and typically resolves with the panic.
What Is Panic Disorder?
Panic disorder is the diagnosis when someone has recurrent, unexpected panic attacks combined with persistent worry about having more attacks or significant behavior changes to avoid them (avoiding places where panic has occurred, carrying emergency medication, restricting activities).
The distinction between “had a panic attack” and “has panic disorder” matters. Many people experience isolated panic attacks during significant stress without developing panic disorder. Panic disorder is the pattern of recurrence plus the anticipatory fear and life changes it causes.
Panic disorder vs generalized anxiety disorder. GAD involves persistent, diffuse worry across life domains, lower intensity, longer duration. Panic disorder involves discrete high-intensity attacks separated by periods of relative calm, plus fear of the next attack. Many patients have both.
Agoraphobia
Agoraphobia is an anxiety disorder involving fear and avoidance of situations where escape might be difficult or help unavailable during a panic attack. Common avoided situations include crowded public places, public transportation, enclosed spaces, open spaces, and being alone outside the home. In severe cases, people become housebound.
Agoraphobia frequently develops as a consequence of panic disorder, driven by the anticipatory fear of having another attack. Early treatment of panic disorder often prevents agoraphobia from taking hold.
Agoraphobia vs social anxiety. Agoraphobia is fear of situations where escape feels impossible or help feels unavailable, usually tied to panic. Social anxiety is fear of social scrutiny, judgment, or embarrassment. Both can lead to avoiding public spaces, but the underlying fear is different.
Social anxiety disorder vs agoraphobia. Social anxiety involves fear of being judged by others. Agoraphobia involves fear of being stuck somewhere unsafe. Many patients have both, but the treatment priorities differ. Social anxiety work focuses on social exposure and cognitive restructuring. Agoraphobia work focuses on graduated exposure to avoided spaces and, usually, treatment of the underlying panic.
Disability and Panic Disorder
Can I get disability for anxiety and panic attacks? Panic disorder can qualify as a disability under the ADA when it substantially limits major life activities, and severe cases can qualify for Social Security Disability. Qualification typically requires documentation from a psychiatrist or licensed mental health professional that demonstrates the frequency, severity, and functional impact of the attacks.
The diagnosis of panic disorder alone does not automatically confer disability status. What matters is the degree to which the condition limits your ability to work, maintain relationships, or carry out daily activities.
How Panic Disorder Is Treated
Panic disorder is highly treatable. Most patients improve significantly with appropriate care.
Medication. SSRIs and SNRIs are first-line treatments for panic disorder, with strong evidence bases. They typically reduce both the frequency and intensity of panic attacks over several weeks. Short-acting medications like benzodiazepines have a role in acute panic management but are not preferred as long-term solo treatment due to dependency concerns. Beta blockers can help with specific situational panic.
Cognitive behavioral therapy. CBT is the gold-standard therapy for panic disorder, with strong evidence that matches or exceeds medication in some studies. CBT for panic teaches interoceptive exposure (deliberately triggering the physical sensations of panic in a controlled setting) and cognitive skills that disrupt the fear-of-fear cycle. Bright Horizons does not provide CBT in-house but coordinates with trusted specialists in the Montgomery County area.
Deep TMS. For patients whose panic disorder has not responded fully to medication, Deep TMS is an FDA-cleared option for related anxiety presentations and may be considered as part of a treatment plan.
Evaluation is the starting point. Panic symptoms can also be caused or worsened by thyroid dysfunction, cardiac conditions, hormonal changes, substance use, or certain medications. A comprehensive psychiatric evaluation rules out mimics and builds a treatment plan around your specific presentation.
