Panic disorder

Panic disorder is an anxiety disorder characterized by recurrent, unexpected panic attacks — sudden surges of intense fear or discomfort that peak within minutes — combined with ongoing concern about further attacks or their consequences, and often with changes in behavior to avoid them.

Panic attacks involve multiple physical and cognitive symptoms such as racing heart, shortness of breath, dizziness, and fear of dying or losing control. The attacks themselves are not dangerous, but the fear of them can severely limit life. Effective treatments include cognitive behavioral therapy (especially interoceptive exposure) and certain medications. Many people improve substantially with care.

A panic attack includes four or more of the following, peaking within minutes:

• Palpitations, pounding heart, or accelerated heart rate
• Sweating
• Trembling or shaking
• Shortness of breath or a sense of smothering
• Feelings of choking
• Chest pain or discomfort
• Nausea or abdominal distress
• Feeling dizzy, unsteady, lightheaded, or faint
• Chills or heat sensations
• Numbness or tingling
• Derealization (feelings of unreality) or depersonalization (being detached from oneself)
• Fear of losing control or “going crazy”
• Fear of dying

Panic disorder additionally involves at least one month of persistent worry about additional attacks or their consequences, or significant maladaptive behavior change (e.g., avoidance of exercise, driving, or crowded places). Attacks may be unexpected or, later, linked to specific situations (panic disorder with agoraphobia).

Panic disorder arises from a combination of biological vulnerability, temperament, and learning. Genetic factors contribute; first-degree relatives have elevated risk. Neurobiological models involve fear-network circuits (amygdala, brainstem, insula) and heightened sensitivity to internal bodily sensations. Cognitive factors — catastrophic misinterpretation of benign physical sensations — help maintain the cycle. Stressful life events and childhood adversity can increase risk. Medical conditions (thyroid disease, cardiac arrhythmias, vestibular problems) and substances (caffeine, stimulants, cannabis, withdrawal from alcohol or sedatives) can trigger or mimic panic and should be considered.

Risk factors include:

• Family history of panic disorder or other anxiety disorders
• Major life stress or traumatic events
• History of physical or sexual abuse in childhood
• Major life transitions
• Female sex (diagnosed more often in women)
• Presence of other anxiety disorders, depression, or asthma
• Temperamental traits such as anxiety sensitivity (fear of anxiety symptoms themselves)

Without treatment, panic disorder can lead to:

• Agoraphobia and progressive avoidance of work, travel, and social life
• Depression and other anxiety disorders
• Increased risk of alcohol or medication misuse as self-treatment
• Financial and relationship strain
• Frequent medical visits for feared physical symptoms
• Reduced quality of life and occupational impairment
• In severe cases, thoughts of suicide — especially when depression coexists

There is no guaranteed prevention. Early treatment of panic attacks and anxiety can reduce the chance that avoidance and full panic disorder develop. Stress-management skills, limiting excess caffeine and stimulants, treating coexisting sleep problems, and seeking help early after a first panic attack are practical steps.

Diagnosis is clinical, based on DSM-5-TR (or equivalent) criteria for recurrent unexpected panic attacks plus worry or behavior change. A medical evaluation helps exclude or identify contributing conditions (thyroid dysfunction, cardiac disease, asthma, substance effects). Screening tools and structured interviews support assessment. Differential diagnosis includes other anxiety disorders, PTSD, OCD, somatic symptom disorders, and medical mimics. Comorbid depression and substance use should be assessed.

See a clinician if panic attacks recur, if you worry constantly about having another attack, or if you avoid activities because of fear of panic. Chest pain and severe shortness of breath should be evaluated urgently to rule out cardiac or other medical causes. If panic symptoms are accompanied by thoughts of self-harm, seek help immediately.

Evidence-based treatments include:

Psychotherapy

• Cognitive behavioral therapy (CBT) with interoceptive exposure — the most specific psychological treatment; teaches that physical sensations are not dangerous and reduces fear through controlled practice
• Situational exposure for agoraphobic avoidance
• Panic-focused psychodynamic therapy and other approaches in selected cases

Medications

• SSRIs and SNRIs — first-line long-term pharmacotherapy
• Benzodiazepines — effective for acute symptom relief but generally reserved for short-term or adjunctive use because of dependence and tolerance risk
• Other agents (e.g., certain anticonvulsants) in selected refractory cases

Combined CBT and medication can be helpful, especially for moderate to severe disorder. Treatment plans should address avoidance, not only attack frequency.

Supportive practices:

• Learn and practice the breathing and grounding techniques taught in therapy
• Gradually face avoided situations with a structured plan rather than total avoidance
• Limit caffeine, alcohol, and recreational drugs
• Maintain regular sleep and exercise
• Use a panic diary to identify patterns and track progress
• Join a reputable support group if helpful
• Take prescribed medicines consistently and discuss side effects early

Bring:

• Description of typical attacks (symptoms, duration, triggers, frequency)
• Ways life has changed because of fear of attacks
• Medical history, medicines, caffeine and substance use
• Prior mental-health treatment
• Questions about CBT, medication options, and expected timeline for improvement
