GO TO THE ER NOW
If you are reading this with any of the following, call 911 (US) or 999 (UK) or 112 (EU) immediately. Do not wait:
- Chest pain that is heavy, crushing, or radiating to your arm, jaw, or back
- Severe shortness of breath at rest
- Fainting or feeling like you will faint
- Slurred speech, confusion, or difficulty speaking
- First-ever episode of these symptoms (cannot assume it is panic disorder without medical evaluation)
This guidance follows Mayo Clinic and American Heart Association protocols. Panic attacks can mimic cardiac emergencies. A chest pain ER visit is the correct call, even if it turns out to be panic-related.
Direct Answer: How Many People Have Panic Disorder?
About 2.7 percent of US adults experience panic disorder in any given year, and 4.7 percent will develop it at some point in their lifetime, according to the National Institute of Mental Health (NIMH) and the National Comorbidity Survey Replication (Kessler, 2006). Women are 2 to 3 times more likely than men to develop panic disorder. The average age of onset is around 24 years, though panic disorder can begin at any age and is rare after age 60. Globally, prevalence ranges from 1 to 3 percent across industrialized countries, with similar rates in Europe and North America and some variation in other regions. Important context: about 11.2 percent of US adults experience at least one panic attack in a given year, but only about 25 percent of those people go on to develop the disorder. A panic attack is common; panic disorder is less common and requires a specific pattern of recurrent unexpected attacks plus at least one month of worry or avoidance behavior. Being diagnosed with panic disorder does not mean you are alone. Millions of adults share this diagnosis and recover with treatment.
US Prevalence: How Common Is Panic Disorder in America?
Past-Year Prevalence
In any given 12-month period, approximately 2.7 percent of US adults have panic disorder. This is known as past-year or current prevalence. Using 2020 US Census data (approximately 258 million adults), this translates to roughly 6.97 million Americans currently experiencing panic disorder at any time.
The National Institute of Mental Health (NIMH) reports this figure based on the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) and the National Comorbidity Survey Replication (NCS-R), the gold-standard epidemiological surveys in the United States. These surveys are rigorous, population-based studies that contact thousands of randomly selected households and conduct in-depth diagnostic interviews.
Lifetime Prevalence
Approximately 4.7 percent of US adults will develop panic disorder at some point in their lifetime, according to Kessler et al. (2006) NCS-R data. This represents about 12.1 million Americans who have ever met the diagnostic criteria for panic disorder. Lifetime prevalence is higher than past-year prevalence because it includes people who currently have the disorder, people who have recovered from it, and people in remission.
Severity Among Those Diagnosed
Of the approximately 2.7 percent of US adults with panic disorder in a given year, about 44.8 percent are classified as having severe panic disorder (NIMH data). Severe panic disorder is defined by significant functional impairment: inability to work, maintain relationships, or perform daily activities without substantial distress or avoidance.
Panic Attacks vs Panic Disorder: Why the Numbers Differ
It is critical to distinguish between having a panic attack and having panic disorder, as the numbers differ dramatically.
Single Panic Attacks Are Common
Approximately 11.2 percent of US adults experience at least one panic attack in any given year. Some epidemiological studies place this figure as high as 15 to 20 percent over a lifetime. A panic attack is a discrete, time-limited episode of intense fear with four or more of 13 physical or cognitive symptoms (rapid heart rate, sweating, trembling, shortness of breath, chest pain, nausea, dizziness, chills, numbness, derealization, depersonalization, fear of losing control, fear of dying), peaking within minutes.
A panic attack can be triggered by a clear stressor (like a near-miss car accident, sudden illness, or terrifying news) or can seem to come out of nowhere. Either way, a single panic attack does not equal panic disorder.
Panic Disorder Requires the Pattern
Only about 25 percent of people who have at least one panic attack go on to develop panic disorder. This means that 8 to 9 percent of US adults have had one or more panic attacks but do not have the disorder. The presence of panic attacks alone does not warrant a panic disorder diagnosis. The clinical criteria require:
- Recurrent unexpected panic attacks (at least two)
- At least one month of persistent worry about future attacks or significant behavior change to avoid them (anticipatory anxiety and avoidance are the key features that define the disorder)
- Functional impairment or distress
This pattern distinguishes panic disorder from simple panic attacks, which may be triggered by acute stress or medical causes and resolve without future worry or life changes.
Demographics: Who Develops Panic Disorder?
Sex and Gender Differences
Women are 1.5 to 3 times more likely than men to develop panic disorder across the lifespan. This is true in the United States, Europe, and globally. Approximately 3 to 4 percent of US women have a past-year panic disorder diagnosis, compared to 1.5 to 2 percent of men. The reasons for this sex difference are not fully understood. Hormonal factors (estrogen, progesterone, menstrual cycle, pregnancy, postpartum period), biological sensitivity, and potential differences in help-seeking or symptom reporting all play roles. Women are also more likely than men to develop other anxiety disorders (generalized anxiety disorder, social anxiety disorder, specific phobias, agoraphobia), suggesting shared biological or environmental risk factors.
Age of Onset
Panic disorder typically emerges in late adolescence or early adulthood. The mean age of onset is approximately 24 years (Kessler et al., 2006). Peak incidence occurs in the teens through the early 30s. Panic disorder can develop at any age, but new-onset panic disorder is rare after age 60. When elderly patients report first panic attack symptoms, medical causes (heart arrhythmia, pulmonary embolism, hyperthyroidism, medication effects) should be thoroughly evaluated before attributing symptoms to primary panic disorder.
Childhood panic disorder is uncommon. Pre-puberty, panic disorder prevalence is less than 1 percent. Prevalence begins to rise in early adolescence (around age 13 to 14) and continues to increase through the teens and early 20s, at which point it stabilizes.
Race and Ethnicity
In the United States, panic disorder prevalence is similar across racial and ethnic groups (White, Black, Hispanic, Asian, Native American populations). Some epidemiological data suggest slightly lower prevalence in Asian-American populations, though this may reflect differences in symptom presentation, illness conceptualization, or help-seeking patterns rather than true biological differences. Cultural factors influence how people experience and report panic symptoms: some cultures place greater emphasis on physical symptoms (heart palpitations, dizziness), while others focus on psychological symptoms (fear of dying, fear of going crazy). These differences in presentation may affect recognition and diagnosis, but underlying panic disorder rates appear similar across groups.
Global Prevalence: How Common Is Panic Disorder Worldwide?
Europe
Panic disorder prevalence in Europe is similar to that in North America. Studies in the United Kingdom, Germany, France, Spain, and other European countries report past-year prevalence rates of 1.5 to 3 percent, consistent with US data. The World Health Organization (WHO) considers panic disorder and anxiety disorders as a significant public health burden across Europe.
Latin America, Africa, and Asia
Wittchen (2010) conducted a systematic review of panic disorder prevalence across multiple countries. In Latin America, reported prevalence ranges from 1 to 2.5 percent. In Asian countries (China, Japan, India), reported prevalence is often lower (0.5 to 1.5 percent). Several factors may explain this variation:
- Diagnostic criteria application: Some countries use ICD-10 (International Classification of Diseases, used in Europe and much of the world) rather than DSM-5. Minor differences in criteria can affect prevalence estimates.
- Symptom presentation: Panic disorder may present differently across cultures. In some Asian populations, for example, somatic (bodily) symptoms predominate, and fear of losing control or dying may be less commonly reported, leading to underdiagnosis.
- Mental health services availability: Countries with fewer mental health services may have lower diagnosed prevalence because many cases go unrecognized.
- Cultural attitudes toward mental health: Stigma or different conceptualizations of mental illness may affect help-seeking and symptom reporting.
Global Prevalence Summary
The WHO estimates that panic disorder and anxiety disorders affect approximately 1 to 3 percent of the global population. Anxiety disorders are among the top 10 causes of years lived with disability (YLD) globally, with panic disorder contributing significantly through chronicity, comorbidity, and agoraphobic complications.
Comorbidity: What Else Do People With Panic Disorder Have?
Panic disorder rarely occurs in isolation. Most people with panic disorder also meet criteria for one or more other mental health conditions, which complicates diagnosis and treatment.
Other Anxiety Disorder Comorbidity
Approximately 50 percent of people with panic disorder have at least one other anxiety disorder, according to the NIMH and published epidemiological studies. Common co-occurring conditions include:
- Agoraphobia (50 to 80 percent of panic disorder patients, though estimates vary)
- Generalized anxiety disorder (40 to 50 percent)
- Social anxiety disorder (15 to 25 percent)
- Specific phobias (40 to 50 percent)
Agoraphobia deserves special mention: it often develops secondary to panic disorder. As panic attacks continue and become more frequent, patients may begin to fear and avoid the places or situations where attacks have occurred (public transportation, shopping malls, crowded stores, leaving home alone, driving on highways). When avoidance becomes extensive, agoraphobia diagnosis is warranted, even though panic disorder triggered it.
Depression Comorbidity
Major depressive disorder co-occurs with panic disorder in 50 to 65 percent of cases. Depression can precede panic disorder, develop after the onset of panic (secondary to chronic anxiety and life disruption), or emerge concurrently. Panic disorder plus depression is associated with greater severity, longer illness duration, and more impaired treatment response compared to panic disorder alone.
Substance Use Comorbidity
About 30 to 40 percent of people with panic disorder have a history of substance use disorder or ongoing substance use problems. Some people use alcohol or benzodiazepines to self-medicate panic symptoms (self-medication hypothesis). Others develop substance use problems as a consequence of using these substances to manage panic, then developing tolerance and dependence. Distinguishing panic-induced substance use from primary substance use disorder is clinically important, as treatment approaches differ.
PTSD Comorbidity
Approximately 20 to 30 percent of panic disorder patients have post-traumatic stress disorder or significant trauma history. Trauma and panic can co-occur independently (two separate conditions), or panic may be triggered by trauma. When both are present, treatment must address both the panic disorder and the underlying trauma.
Trends: Are Panic Disorder Rates Rising?
Post-COVID-19 Increase in Anxiety Disorders
Since 2020, several epidemiological studies and clinical surveys have reported increased rates of anxiety disorders, including panic disorder, particularly in younger adults and college-age populations. Twenge et al. (2022) and other researchers noted rises in anxiety diagnoses and anxiety-related emergency department visits in 2020 and 2021. The pandemic-related stress (isolation, uncertainty, health threats, economic disruption) appears to have increased the prevalence of anxiety disorders among vulnerable populations.
Whether these increases represent true increases in panic disorder incidence or increased help-seeking (and thus detection) is not yet fully clear. As more longitudinal data accumulate, the long-term trajectory will become clearer.
Historical Perspective
Panic disorder was defined as a distinct psychiatric diagnosis only in 1980 with the publication of the DSM-III. Before that, panic symptoms were often misattributed to cardiac disease or labeled as "psychosomatic." The recognition of panic disorder as a diagnosis has increased awareness and help-seeking, which may explain some apparent historical increases in prevalence. However, the syndrome itself (sudden, unexpected episodes of intense fear with physical symptoms) has been documented in medical literature for centuries.
The Treatment-Seeking Gap: Why Most People With Panic Disorder Do Not Receive Care
Despite clear prevalence figures, only a fraction of people with panic disorder receive any professional treatment in a given year.
Treatment Utilization Rates
Approximately 35 percent of people with panic disorder receive any form of mental health treatment (psychiatric medications, psychotherapy, or both) in any given 12-month period (NIMH, National Survey of Mental Health and Wellbeing data). This means that 65 percent of people with current panic disorder are not receiving professional care.
Barriers to Treatment
Reasons for this gap include:
- Lack of diagnosis: Many people experience panic attacks and panic disorder symptoms but are never formally diagnosed. Symptoms may be attributed to medical causes (heart disease, thyroid problems, inner ear dysfunction), and medical workup may not reveal a clear cause, leaving patients confused and untreated.
- Cost and insurance: Mental health treatment, especially psychotherapy (cognitive-behavioral therapy for panic), can be expensive. Insurance coverage varies. Many people cannot afford out-of-pocket costs.
- Availability: Shortages of mental health professionals, particularly therapists trained in evidence-based panic treatment, make access difficult in many regions.
- Stigma: Despite increased awareness, mental health stigma remains a barrier. Some people are reluctant to seek psychiatric care due to shame or fear of judgment.
- Lack of awareness: Some people with panic disorder do not recognize their symptoms as a treatable condition or do not know where to seek help.
- Long delays from onset to treatment: Even among those who eventually seek help, the average delay from first panic attack to first specialist visit is 5 to 10 years (NAMI, National Alliance on Mental Illness data). This prolonged untreated period increases symptom severity, disability, and risk of depression and substance use problems.
Why "How Many" Matters: Reducing Shame and Isolation
One of the most powerful aspects of understanding panic disorder epidemiology is recognizing that you are not alone. Knowing that millions of adults have panic disorder, that it is one of the most common anxiety disorders, and that it is treatable can reduce shame and the sense of isolation that often accompanies the condition.
People with untreated or newly diagnosed panic disorder often feel uniquely vulnerable, afraid, or broken. The internal experience can feel alien and terrifying. Learning that 1 in 37 US adults experiences this condition in any given year, that women you know likely have similar experiences (even if not disclosed), and that panic disorder is as common as specific phobias or depression can be profoundly reassuring.
Panic disorder is not rare. It is not a sign of weakness or serious psychological pathology. It is a highly treatable anxiety disorder. The first step toward recovery is often simply knowing that the condition is real, recognized by medical professionals, and that effective treatments exist.
Disability Burden: The Global Impact of Panic Disorder
Beyond prevalence figures, understanding the burden of panic disorder requires looking at its impact on quality of life and disability.
Years Lived With Disability (YLD)
The WHO tracks years lived with disability (YLD), a metric that captures how many years of life are lived with the functional consequences of a condition. Anxiety disorders, collectively, rank in the top 10 global causes of years lived with disability. Panic disorder, as one of the most disabling anxiety disorders, contributes significantly to this burden.
The disability from panic disorder stems from:
- Agoraphobic complications: As avoidance expands, people may become housebound or severely limited in where they can go.
- Work disruption: Panic disorder often leads to missed workdays, reduced productivity, job loss, or inability to work.
- Relationship strain: Panic disorder can increase dependency on partners or family members, leading to relationship conflict.
- Comorbidity: The high rates of comorbid depression and substance use disorder compound disability.
Quality of Life Impact
People with panic disorder report lower quality of life compared to the general population, even after controlling for comorbid conditions. Social isolation, reduced independence, and chronic anticipatory anxiety all contribute to a diminished sense of wellbeing and life satisfaction.
Pediatric Prevalence: When Does Panic Disorder Begin?
Pre-Adolescence
Panic disorder is extremely rare in children before puberty. Prevalence in children under age 12 is less than 1 percent. Panic attacks can occur in children, but panic disorder (the syndrome with anticipatory worry and avoidance lasting months or years) is uncommon.
Adolescence
Panic disorder prevalence rises throughout adolescence. By mid-to-late adolescence (ages 15 to 19), prevalence reaches approximately 2 to 3 percent, approaching adult levels. Early adolescence (ages 11 to 14) shows intermediate prevalence.
Why Panic Disorder Emerges in Adolescence
The reasons for the emergence of panic disorder in adolescence are not fully understood. Possible factors include:
- Developmental brain changes: Adolescence is marked by substantial changes in brain development, particularly in areas involved in emotion regulation, fear processing, and self-awareness.
- Hormonal changes: Puberty and hormonal fluctuations may alter susceptibility to anxiety.
- Psychosocial stressors: Adolescence brings increased academic pressure, social stress, romantic relationships, and identity exploration, all potential triggers.
- Genetic vulnerability meeting environmental stress: The gene-environment interaction model suggests that genetic risk for anxiety may be expressed during times of developmental vulnerability and increased stressor exposure.
FAQ: How Many People Have Panic Disorder?
1. How common is panic disorder?
Panic disorder affects approximately 2.7 percent of US adults in any given year and 4.7 percent lifetime. Globally, prevalence ranges from 1 to 3 percent. This makes it one of the more common anxiety disorders.
2. What percentage of people have panic attacks, versus panic disorder?
About 11.2 percent of US adults experience at least one panic attack per year. However, only about 25 percent of those people develop panic disorder. The remaining 75 percent have a panic attack or two and never develop the disorder.
3. Are panic attacks more common in women than men?
Yes. Panic attacks occur in both men and women but are more common in women. Panic disorder, the full syndrome, is 1.5 to 3 times more common in women than in men.
4. Is panic disorder rare?
No. Panic disorder is not rare. It affects millions of people. In the United States alone, approximately 6.97 million adults have panic disorder in any given year. It is less common than specific phobias or generalized anxiety disorder but more common than PTSD or OCD.
5. Why are panic disorder rates rising?
Some recent data suggest increases in anxiety disorders post-COVID-19, particularly in younger populations. However, pandemic-related increases may reflect heightened help-seeking and increased awareness rather than true biological increases. Historically, recognition of panic disorder as a distinct diagnosis (formalized in 1980) has increased reported prevalence as awareness and diagnostic practices improved.
6. What age does panic disorder usually start?
Panic disorder typically begins in late adolescence or early adulthood, with mean onset around age 24 years. The age range is broad (teens through early 30s). Panic disorder can start at any age but new-onset after age 60 is uncommon and should prompt medical evaluation for secondary causes (heart arrhythmia, thyroid disease, medication effects).
7. Can panic disorder run in families?
Yes. Family history of panic disorder, anxiety disorders, depression, or bipolar disorder increases the risk of developing panic disorder. Twin studies suggest that panic disorder has a heritability of approximately 30 to 40 percent, meaning genetics account for about one-third to two-fifths of the liability, while environment accounts for the remainder.
8. How many panic disorder patients get treatment?
Only about 35 percent of people with panic disorder receive professional mental health treatment (therapy or medication) in any given year. This treatment gap is due to lack of diagnosis, cost, availability of services, stigma, and lack of awareness that panic disorder is treatable.
