[Resource Guide] Comprehensive Diagnostic Criteria For Panic Disorder (DSM-5 / ICD-11)

Panic disorder is a debilitating anxiety disorder characterized by sudden, repeated episodes of intense fear accompanied by physical symptoms. For clinicians, researchers, and mental health professionals, accurate diagnosis is the critical first step toward effective treatment.

This resource guide provides a detailed breakdown of the diagnostic criteria for Panic Disorder under both the DSM-5-TR (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision) and the ICD-11 (International Classification of Diseases, 11th Revision).


Understanding Panic Disorder vs. Panic Attacks

Before diagnosing panic disorder, it is vital to distinguish between a panic attack and panic disorder.

  • Panic Attack: An abrupt surge of intense fear or intense discomfort that reaches a peak within minutes. Panic attacks can occur within the context of any anxiety disorder as well as other mental disorders (e.g., depressive disorders, PTSD, substance use disorders) and some medical conditions.
  • Panic Disorder: A chronic psychiatric condition characterized specifically by recurrent, unexpected panic attacks, followed by persistent worry about future attacks or significant behavioral changes designed to avoid them.

DSM-5-TR Diagnostic Criteria for Panic Disorder

The American Psychiatric Association (APA) outlines specific criteria in the DSM-5-TR to standardize the diagnosis of panic disorder. To meet the criteria for Panic Disorder (F41.0), a patient must satisfy all four of the following diagnostic domains (Criteria A–D):

Criterion A: Recurrent, Unexpected Panic Attacks

The individual must experience recurrent (more than one) and unexpected panic attacks. An unexpected attack occurs "out of the blue," without an obvious trigger or situational cue.

During these attacks, four (or more) of the following 13 symptoms must occur abruptly and reach a peak within minutes:

| Symptom Category | Diagnostic Symptom | Description / Clinical Presentation | | :--- | :--- | :--- | | Cardiovascular & Respiratory | 1. Palpitations | Pounding heart, accelerated heart rate, or racing pulse. | | | 2. Sweating | Profuse diaphoresis not caused by environmental temperature. | | | 3. Shortness of Breath | Sensations of dyspnea, smothering, or being unable to catch one's breath. | | | 4. Choking Feelings | Sensation of a lump in the throat or globus hystericus. | | | 5. Chest Pain | Chest tightness, pressure, or discomfort (often mimicking a myocardial infarction). | | Gastrointestinal & Neurological | 6. Nausea | Abdominal distress, cramping, or sudden gastrointestinal upset. | | | 7. Dizziness | Feeling unsteady, light-headed, faint, or experiencing vertigo. | | | 8. Paresthesias | Numbness or tingling sensations (frequently in the hands, feet, or perioral area). | | | 9. Trembling | Shaking, shivering, or visible tremors in the extremities. | | Sensory & Thermoregulatory | 10. Chills or Heat Sensations | Sudden hot flashes or cold, clammy shivers. | | | 11. Derealization / Depersonalization | Feelings of unreality (derealization) or being detached from oneself (depersonalization). | | Cognitive | 12. Fear of Losing Control | Fear of "going crazy," acting impulsively, or losing cognitive grip. | | | 13. Fear of Dying | An overwhelming sense of impending doom or immediate mortality. |

Note: If fewer than 4 of the above symptoms are present, the episode is classified as a limited-symptom panic attack.

Criterion B: Anticipatory Worry or Behavioral Changes

At least one of the attacks must be followed by 1 month (or more) of one or both of the following:

  1. Persistent worry or concern about additional panic attacks or their consequences (e.g., losing control, having a heart attack, "going crazy").
  2. A significant maladaptive change in behavior related to the attacks (e.g., behaviors designed to avoid having panic attacks, such as avoiding exercise, unfamiliar locations, or social situations).

Criterion C: Exclusion of Substances and Medical Conditions

The panic attacks cannot be attributable to the physiological effects of a substance (e.g., illicit drugs, prescription medications, caffeine) or another medical condition (e.g., hyperthyroidism, cardiopulmonary disorders).

Criterion D: Exclusion of Other Mental Disorders

The panic attacks are not better explained by another mental disorder. For example:

  • Not restricted to feared social situations (as in Social Anxiety Disorder).
  • Not restricted to circumscribed phobic objects or situations (as in Specific Phobia).
  • Not restricted to reminders of traumatic events (as in PTSD).
  • Not restricted to separation from attachment figures (as in Separation Anxiety Disorder).

ICD-11 Diagnostic Criteria for Panic Disorder

Published by the World Health Organization (WHO), the ICD-11 classifies Panic Disorder under code 6B01.

Key Features of Panic Disorder in ICD-11

For a diagnosis of Panic Disorder under ICD-11, the clinical presentation must meet the following guidelines:

  1. Recurrent Panic Attacks: The individual experiences recurrent panic attacks that are not restricted to particular situations or environmental stimuli (i.e., they are unexpected).
  2. Lack of Predictability: The attacks do not consistently occur in response to specific, predictable triggers.
  3. Secondary Psychological/Behavioral Symptoms: The panic attacks are followed by persistent apprehension or worry about their recurrence or their consequences, or by significant avoidance behavior (e.g., avoiding places where help might not be available).
  4. Duration: The symptoms must persist for at least several weeks.
  5. Functional Impairment: The symptoms result in significant distress or significant impairment in personal, family, social, educational, occupational, or other important areas of functioning.

Side-by-Side Comparison: DSM-5-TR vs. ICD-11

While both diagnostic manuals aim to capture the same underlying pathology, key differences exist in their framing, symptom thresholds, and duration requirements.

| Diagnostic Feature | DSM-5-TR | ICD-11 | | :--- | :--- | :--- | | Symptom Threshold | Requires a strict threshold of $\ge$ 4 out of 13 specific symptoms. | Focuses on the core descriptive experience; does not enforce a rigid numerical symptom cutoff. | | Duration Requirement | Symptoms must persist for at least 1 month following an attack. | Symptoms must persist for at least several weeks. | | Agoraphobia Coding | Diagnosed as a separate, co-occurring condition if criteria for both are met. | Diagnosed as either "Panic Disorder" or "Panic Disorder with Agoraphobia" (using linked coding). | | Primary Focus | Highly structured, criteria-driven checklist. | Clinical utility-focused, characterization-based description. |


Differential Diagnosis: Ruling Out Mimics

Because the physical symptoms of a panic attack are highly somatic, clinicians must rule out several medical and psychiatric conditions before confirming a diagnosis of panic disorder.

                  [ Patient Presents with Panic Symptoms ]
                                     |
         +---------------------------+---------------------------+
         |                                                       |
[ Rule Out Medical Conditions ]                         [ Rule Out Other Psychiatric Disorders ]
 - Cardiovascular (Arrhythmias)                          - Generalized Anxiety Disorder (GAD)
 - Endocrine (Hyperthyroidism, Pheochromocytoma)         - PTSD (Trauma-related triggers)
 - Respiratory (Asthma, COPD)                            - Social Anxiety Disorder (SAD)
 - Substance-Induced (Caffeine, Stimulants)              - OCD (Obsession-triggered panic)

1. Medical Conditions to Rule Out

  • Cardiovascular Disorders: Cardiac arrhythmias, mitral valve prolapse, angina.
  • Endocrine Disorders: Hyperthyroidism, hypoglycemia, pheochromocytoma.
  • Respiratory Disorders: Asthma, chronic obstructive pulmonary disease (COPD), pulmonary embolism.
  • Neurological Disorders: Vestibular dysfunction, seizure disorders (e.g., temporal lobe epilepsy).

2. Substance-Induced Etiologies

  • Intoxication: Caffeine, amphetamines, cocaine, cannabis, or other stimulants.
  • Withdrawal: Alcohol, benzodiazepines, barbiturates, or sedatives.

3. Other Psychiatric Disorders

  • Generalized Anxiety Disorder (GAD): Worry in GAD is focused on everyday life events and is generalized, whereas in panic disorder, the worry is specifically focused on the recurrence and physical consequences of panic attacks.
  • Post-Traumatic Stress Disorder (PTSD): Panic attacks in PTSD are typically triggered by internal or external reminders of a specific traumatic event.

Clinical Assessment Tools

To assist in the objective measurement of symptom severity and treatment progress, clinicians should utilize validated psychometric scales:

  1. Panic Disorder Severity Scale (PDSS): A 7-item clinician-administered scale that rates panic frequency, distress during attacks, anticipatory anxiety, agoraphobic avoidance, and work/social impairment.
  2. Symptom Checklist-90-R (SCL-90-R) - Anxiety Subscale: Helps identify broader somatic and psychological anxiety markers.
  3. The Panic and Agoraphobia Scale (PAS): Particularly useful for monitoring the efficacy of pharmacological and cognitive-behavioral interventions over time.
