Panic Disorder: Panic Attacks, Symptoms, and Treatment

Introduction

Panic disorder is an anxiety condition characterised by recurrent, unexpected panic attacks — sudden intense episodes of fear and physical symptoms — combined with ongoing worry about future attacks and their consequences. Panic attacks feel overwhelming, but they are not physically dangerous. With effective treatment, most people make an excellent recovery.

Key Points

Panic attacks are sudden surges of intense fear accompanied by physical symptoms — rapid heartbeat, chest tightness, breathlessness, dizziness.
Panic disorder develops when attacks recur unexpectedly and the person begins to fear and avoid situations associated with them.
Chest pain and breathing difficulties during panic can mimic heart symptoms — new, severe, or unusual symptoms should always be assessed urgently.
CBT is the most effective treatment; SSRIs and SNRIs are the first-line medications.
Most people with panic disorder recover well with the right treatment.

Background

Panic disorder affects approximately 2–3% of the population at some point in their lives. It most commonly begins in early adulthood, though it can start at any age. Women are diagnosed approximately twice as often as men, though men may be less likely to seek help.

A panic attack is a brief, intense activation of the body’s threat response — the “fight or flight” reaction — in the absence of real external danger. The brain misreads internal sensations (such as a slightly elevated heart rate) as signs of catastrophic threat, which intensifies the physical response, which intensifies the fear: a rapid escalating cycle.

Over time, many people with panic disorder begin to avoid situations where they fear a panic attack might occur, or where escape might be difficult — this can lead to significant restriction of daily life, including agoraphobia in some cases.

What Does a Panic Attack Feel Like?

Panic attacks typically involve some or all of the following:

Rapid or pounding heartbeat (palpitations)
Chest pain, pressure, or tightness
Shortness of breath or difficulty breathing
Dizziness, light-headedness, or feeling faint
Sweating, chills, or hot flushes
Trembling or shaking
Tingling or numbness (often in the hands or face)
Nausea or stomach discomfort
Feeling detached from oneself or surroundings (derealisation or depersonalisation)
A sense of impending doom or danger
Fear of losing control, fainting, or dying

Most panic attacks peak within 5–10 minutes and resolve within 20–30 minutes. They are distressing but not physically dangerous.

Panic Disorder vs General Anxiety

Both involve excessive fear, but they differ in character:

	Panic Disorder	Generalised Anxiety
Onset	Sudden, discrete episodes	Persistent background worry
Physical symptoms	Intense and acute	Often milder and chronic
Focus of fear	Panic attacks themselves	Many topics (health, work, family)
Pattern	Episodic	Ongoing

Panic disorder and generalised anxiety disorder often co-occur. Depression is also common in people with panic disorder.

Panic Attack or Heart Problem?

This is one of the most important questions in panic disorder, and one that genuinely requires clinical judgement.

Similarities: Panic attacks and cardiac events can both cause chest pain, rapid heartbeat, shortness of breath, and dizziness. First-time panic attacks are frequently assessed in emergency departments because the physical experience is so alarming.

Seek emergency medical assessment if:

Chest pain is severe, crushing, or pressure-like
Pain spreads to the arm, jaw, neck, or back
Symptoms include fainting or actual loss of consciousness
You experience sudden severe shortness of breath at rest
New neurological symptoms appear — facial drooping, arm weakness, slurred speech
Symptoms feel clearly different from your usual panic attacks
You are unsure whether this is panic or something else

People with established panic disorder still develop cardiac or other medical conditions. The fact that you have had panic attacks before does not mean new or unusual symptoms should be dismissed. When in doubt, seek assessment. A doctor can help distinguish panic from cardiac symptoms — but never delay emergency care to find out.

What Triggers Panic Attacks?

Panic attacks can feel as though they come from nowhere, but common triggers include:

Caffeine, stimulants, or certain medications
Sleep deprivation
Physical illness — fever, thyroid dysfunction, heart arrhythmias
Stress or overwork
Hyperventilation
Confronting avoided situations
Alcohol withdrawal

Identifying personal triggers is part of effective management, but the unpredictability of panic is itself part of what makes the condition distressing.

What to Do During a Panic Attack

Remind yourself it will pass. Panic attacks are time-limited. The physical sensations are produced by adrenaline and will subside.
Slow your breathing. Breathe in for 4 counts, out for 6. Breathing out more slowly than you breathe in activates the parasympathetic nervous system.
Try grounding. Name 5 things you can see, 4 you can touch, 3 you can hear.
Stay in the situation if safe. If you can tolerate remaining where you are, this prevents avoidance from reinforcing future panic.
Do not add secondary fear. The “fear of the fear” escalates panic. Try to accept the sensations rather than fight them.

If symptoms are severe, new, or you are unsure whether this is panic or a medical emergency, seek help.

Diagnosis

Panic disorder is diagnosed by a clinician — usually a GP, psychologist, or psychiatrist — based on:

Recurrent, unexpected panic attacks
At least one month of persistent worry about future attacks, their consequences, or significant behaviour change as a result
Symptoms not better explained by a medical condition, substance use, or another mental health disorder

A medical assessment is usually appropriate when panic disorder is first suspected, to exclude conditions that can mimic panic — including cardiac arrhythmias, thyroid disease, hypoglycaemia, and phaeochromocytoma.

Treatment and Management

Cognitive Behavioural Therapy (CBT)

CBT is the most effective treatment for panic disorder. It addresses:

Catastrophic misinterpretation of bodily sensations — learning to interpret a racing heart as benign rather than as a sign of imminent danger
Interoceptive exposure — deliberately inducing mild versions of feared physical sensations (such as spinning in a chair or breathing through a coffee straw) to break the association between sensation and catastrophe
Situational exposure — gradually returning to avoided places and situations
Safety behaviours — identifying and reducing behaviours that provide short-term reassurance but maintain anxiety long-term (e.g., always sitting near exits, constantly monitoring heart rate)

CBT for panic disorder is highly effective and produces lasting results. Most programmes involve 8–16 sessions.

Medication

SSRIs (e.g., sertraline, escitalopram): first-line medication for panic disorder; take 4–6 weeks for full effect.
SNRIs (e.g., venlafaxine): also evidence-based.
Short-term medication (benzodiazepines): occasionally used in acute situations but carry risks of dependence and are not recommended for long-term use. Discuss carefully with your doctor.

Medication and CBT combined can be more effective than either alone, particularly for moderate to severe panic disorder.

Breathing and grounding skills

Diaphragmatic breathing, paced breathing, and grounding techniques are useful tools during acute episodes — not cures on their own, but valuable complements to therapy.

Lifestyle factors

Reducing caffeine and alcohol (both can lower the panic threshold)
Regular physical activity
Adequate sleep
Stress management

When to Seek Urgent Help

Seek emergency care if:

You experience severe chest pain, especially with arm or jaw pain
You faint or lose consciousness

FAQ

Q: What is a panic attack? A: A sudden surge of intense fear accompanied by physical symptoms — racing heart, chest tightness, breathlessness, dizziness — that peaks within minutes and resolves within 20–30 minutes. Frightening but not physically dangerous.

Q: Is panic disorder the same as anxiety? A: Panic disorder is a specific anxiety disorder defined by recurrent unexpected panic attacks and persistent worry about them. It differs from generalised anxiety, which involves persistent background worry rather than discrete acute episodes.

Q: How do I know if it’s a panic attack or a heart problem? A: The symptoms overlap. If chest pain is severe, crushing, spreads to the arm or jaw, is accompanied by fainting, or feels different from usual panic — seek emergency care. When in doubt, get assessed.

Q: Can panic attacks cause physical harm? A: Panic attacks themselves are not physically dangerous. The sensations are produced by the adrenaline response. New or unusual symptoms should still be assessed medically.

Q: How is panic disorder treated? A: CBT is the most effective treatment. SSRIs and SNRIs are the first-line medications. Most people recover well with appropriate care.
