Abrupt attacks that peak within minutes separate panic disorder from generalized anxiety disorder.
Side by side
Generalized anxiety disorder presents as persistent uncontrollable worry across multiple life domains for at least 6 months.
Panic disorder presents with recurrent unexpected panic attacks and at least 1 month of concern or behavior change due to future attacks.
Chronic threat anticipation and autonomic hypervigilance sustain broad persistent worry states.
Abrupt surges of fear with sympathetic activation create recurrent panic cycles and anticipatory avoidance.
Diagnosis is clinical after medical exclusion when indicated; symptoms include restlessness, fatigue, poor concentration, irritability, muscle tension, and sleep disturbance over at least 6 months.
Diagnosis is clinical and requires recurrent unexpected attacks with abrupt peak in minutes and persistent worry or maladaptive avoidance for at least 1 month.
The trap
Patients with panic attacks are mislabeled as having only generalized anxiety, leading to under-recognition of interattack avoidance and recurrent emergency visits; documenting discrete attack onset and postattack fear of recurrence is essential.
The repair move
Next best step: rule out immediate cardiopulmonary emergencies if symptoms are active, then diagnose panic disorder when recurrent unexpected attacks and avoidance are present. Start CBT with exposure and an SSRI such as escitalopram 10 mg daily; for acute bridge in severe cases, a short benzodiazepine course can be used while SSRI benefit develops over several weeks. For generalized anxiety disorder, use CBT plus SSRI or SNRI focused on chronic worry control.
Try a free question
CoreA 27-year-old man has recurrent episodes of abrupt palpitations, dyspnea, and intense fear that peak within 8 minutes and resolve in 20 minutes. BP 128/76 mm Hg, HR 86/min, temp 36.5 C between attacks. ECG and troponin are normal. What is the most likely diagnosis?
Show answer and explanation
Answer: A. Panic disorder. Unexpected recurrent attacks peaking within minutes with negative cardiac evaluation are classic for panic disorder.
Why the other choices are tempting
- B. Wrong because generalized anxiety disorder is chronic diffuse worry, not discrete sudden attacks.
- C. Wrong because social anxiety attacks are triggered primarily by social performance situations.
- D. Wrong because the pattern is paroxysmal fear, not persistent distress over multiple bodily symptoms.
- E. Wrong because there are no obsessions or compulsive rituals.
