Introduction
Panic Disorder is an anxiety disorder characterized by recurrent, unexpected panic attacks — sudden surges of intense fear or physical discomfort that peak within minutes — along with persistent concern about future attacks or significant behavioral changes related to the attacks. Panic attacks themselves are not dangerous, but the fear of having them can profoundly restrict a person's life and activities.
Causes
Panic disorder likely develops from a combination of biological vulnerability, psychological sensitivity to anxiety sensations, and environmental triggers. Dysregulation of the body's fight-or-flight response and heightened sensitivity in brain regions such as the amygdala contribute to the disorder. Genetic factors, a history of anxiety or childhood adversity, and significant life stressors may all precipitate the onset of panic disorder. Caffeine and certain medications can also trigger panic-like symptoms.
Symptoms
Panic attacks involve at least four symptoms from a defined list, including rapid heartbeat, sweating, trembling, shortness of breath, chest pain, nausea, dizziness, numbness or tingling, chills or hot flashes, feelings of unreality or detachment, and intense fear of dying or losing control. Following recurrent attacks, individuals often develop persistent anticipatory anxiety and may begin avoiding situations they associate with having an attack (avoidance behavior).
Diagnosis
A clinician diagnoses panic disorder when a patient reports recurrent unexpected panic attacks followed by at least one month of persistent concern about future attacks, worry about their consequences, or notable behavioral changes. Medical conditions that can mimic panic (thyroid disorders, cardiac arrhythmias, hypoglycemia) must be ruled out. Assessment also covers the extent of avoidance and any co-occurring conditions such as agoraphobia or depression.
Treatment
Cognitive behavioral therapy (CBT) is highly effective for panic disorder, helping patients understand the physiology of panic, challenge catastrophic thinking, and conduct gradual exposures to feared sensations and situations. SSRIs and SNRIs are first-line medications, with benzodiazepines occasionally used short-term for acute symptom relief. Breathing retraining and other relaxation techniques can complement formal treatment. Most patients achieve significant symptom reduction with appropriate care.
