Anxiety Disorder vs Panic Disorder

Clinical comparison — shared symptoms, key differences, distinguishing diagnostic tests, treatment pathways, and when to seek urgent evaluation.

Condition Overview

Condition A

Anxiety Disorder

Anxiety disorders are among the most common mental health conditions, characterized by excessive fear, worry, or nervousness that interferes with daily activities. Types include generalized anxiety disorder (GAD), panic disorder, and social anxiety.

Condition B

Panic Disorder

Panic disorder is characterized by recurrent unexpected panic attacks with intense physical symptoms. It often leads to persistent worry about future attacks and behavioral avoidance.

palpitations shortness of breath dizziness chest pain anxiety

Key Clinical Differences

Anxiety Disorder

Palpitations, dizziness, shortness of breath
Anxiety, worry, and apprehension
Avoidance behaviours
Functional impairment

Panic Disorder

Discrete panic attacks: sudden intense fear peaking within 10 minutes
Somatic symptoms: tachycardia, sweating, trembling, chest pain
Anticipatory anxiety about future attacks
Agoraphobia may develop

Distinguishing Diagnostic Tests

Test	Anxiety Disorder	Panic Disorder
Clinical interview (DSM-5)	Persistent excessive worry about multiple domains for ≥6 months (GAD)	Recurrent unexpected panic attacks + anticipatory anxiety/behaviour change
Panic attack diary	Generalised anxiety without discrete attacks	Discrete attacks with sudden peak, often unprovoked
Cardiac and thyroid workup	Normal — anxiety is primary	Normal — must exclude cardiac arrhythmia and hyperthyroidism

Treatment Approaches

Anxiety Disorder

•SSRIs/SNRIs for GAD
•Buspirone for generalised anxiety
•CBT (worry management, problem-solving)
•Short-term benzodiazepines (caution)

Panic Disorder

•SSRIs/SNRIs
•CBT with interoceptive exposure — gold standard
•Short-term alprazolam or clonazepam
•Breathing retraining to abort attacks
