For Patients & General Readers
Panic Disorder is a condition where people experience sudden, intense episodes of fear or discomfort called panic attacks. These attacks can feel overwhelming and are often accompanied by physical symptoms like a racing heart or shortness of breath. It matters because it can significantly interfere with daily life and lead to avoidance of situations that trigger these feelings.
Clinical Overview
Panic Disorder is characterized by recurrent, unexpected panic attacks and persistent worry about future attacks or their consequences. Diagnosis requires the presence of at least one month of persistent concern or behavioral change related to the attacks. It is a significant cause of functional impairment and reduced quality of life.
Clinical Presentation
- Recurrent unexpected panic attacks, defined as a sudden surge of intense fear or discomfort that reaches a peak within minutes.
- At least one of the following in a month of the attacks: persistent concern about having additional attacks, worry about the implications of the attack, or a significant change in behavior related to the attacks.
- Absence of a substance (e.g., drug of abuse, medication) or another medical condition (e.g., hyperthyroidism, pulmonary embolism) as the direct physiological effect.
- The panic attacks are not better explained by another mental disorder, such as social anxiety disorder, specific phobia, obsessive-compulsive disorder, posttraumatic stress disorder, or dissociative identity disorder.
- Significant distress or impairment in social, occupational, or other important areas of functioning.

Differential Diagnoses
| Condition | Distinguishing Feature |
|---|
| Generalized Anxiety Disorder (GAD) | GAD involves excessive worry about a variety of topics, whereas panic disorder is characterized by discrete, intense panic attacks. |
| Social Anxiety Disorder (SAD) | SAD involves fear and avoidance of social situations due to fear of scrutiny, while panic attacks in panic disorder can occur in any situation. |
| Specific Phobia | Phobias are triggered by specific objects or situations, whereas panic attacks in panic disorder can be unexpected. |
| Agoraphobia | Agoraphobia involves fear and avoidance of situations from which escape might be difficult or help unavailable during panic-like symptoms, often occurring with or without panic disorder. |
| Hyperthyroidism | Can mimic anxiety symptoms, including palpitations, tremor, and sweating, but usually accompanied by other signs like weight loss and heat intolerance. |
| Pulmonary Embolism | Can present with sudden shortness of breath, chest pain, and tachycardia, but often has risk factors and may have other signs like hemoptysis. |
| Cardiac Arrhythmias (e.g., SVT, Afib) | Can cause palpitations and dizziness, but ECG will reveal characteristic rhythm abnormalities. |
| Pheochromocytoma | Rare adrenal tumor causing episodic hypertension, palpitations, and sweating, but usually associated with headaches and can be diagnosed with urine/serum catecholamines. |
Red Flags — Seek Immediate Care
- Chest pain suggestive of myocardial infarction.
- Sudden onset of severe shortness of breath with hypoxia, suggestive of pulmonary embolism or pneumothorax.
- Neurological deficits suggesting stroke or transient ischemic attack.
- Suicidal ideation or intent, which can be elevated in individuals with severe anxiety disorders.
Key Investigations
- Comprehensive medical history and physical examination to rule out organic causes.
- Electrocardiogram (ECG) to assess for cardiac arrhythmias or ischemia.
- Thyroid function tests (TSH, free T4) to rule out hyperthyroidism.
- Complete blood count (CBC) and basic metabolic panel (BMP) to assess general health and rule out electrolyte imbalances.
- Consider toxicology screen if substance abuse is suspected.
- Consider Holter monitor or event recorder if paroxysmal arrhythmias are suspected.
Management Overview
Treatment for Panic Disorder typically involves a combination of psychotherapy, most notably Cognitive Behavioral Therapy (CBT) which focuses on challenging maladaptive thoughts and behaviors, and pharmacotherapy, with selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs) as first-line agents. Benzodiazepines may be used for short-term relief of acute symptoms but carry risks of dependence.
