According to DSM-5 criteria, what is the minimum number of panic attacks required within a specific timeframe to diagnose panic disorder?

Explanation

## DSM-5 Diagnostic Criteria for Panic Disorder **Key Point:** Panic disorder diagnosis does NOT require a fixed number of panic attacks. Instead, it requires at least one unexpected panic attack followed by ≥1 month of persistent worry or behavioral change. ### DSM-5 Criterion A: Recurrent Unexpected Panic Attacks The essential feature is: - **≥1 unexpected panic attack** (not triggered by external cues) - Followed by ≥1 month of either: 1. Persistent worry about having another attack, OR 2. Maladaptive behavioral changes (avoidance, safety behaviors) ### Why This Matters Clinically **High-Yield:** The diagnosis hinges on the **consequences** of the panic attack (anticipatory anxiety and avoidance), not on attack frequency. A single panic attack + 1 month of worry = panic disorder. Multiple attacks without worry ≠ panic disorder. **Mnemonic: "One + Worry"** — One panic attack + One month of worry/behavioral change = Panic Disorder diagnosis. ### Distinction from Panic Attacks Alone | Feature | Isolated Panic Attack | Panic Disorder | | --- | --- | --- | | Number of attacks | 1 or more | ≥1 unexpected | | Anticipatory anxiety | Absent | Present (≥1 month) | | Avoidance behavior | Absent | Present | | Functional impairment | Minimal | Significant | | Diagnosis | Not a disorder | Anxiety disorder | **Clinical Pearl:** Many patients experience a single panic attack in their lifetime without developing panic disorder. The transition to disorder occurs when fear of the panic itself becomes the primary problem. [cite:DSM-5 (American Psychiatric Association 2013), Kaplan & Sadock's Synopsis of Psychiatry 11e Ch 9]
