Which condition is listed as a stroke mimic and is not a primary neurological disease?

• A. Sepsis
• B. Migraine
• C. Seizure
• D. Conversion Disorder

Answer: (D)

Stroke mimics are conditions that produce sudden focal neurologic symptoms like a stroke, but without a vascular event in the brain. Conversion disorder fits this idea beautifully: it’s a functional neurological symptom disorder in which patients experience real-looking motor or sensory deficits that have no identifiable brain lesion or vascular cause. The symptoms can mimic weakness, numbness, or speech problems seen with a real stroke, yet objective testing and imaging are typically normal, signaling that there isn’t an underlying primary neurological disease. That combination—stroke-like presentation without a true brain injury—makes conversion disorder a classic stroke mimic that is not a primary neurological disease. By contrast, migraine and seizure are neurological disorders themselves, and sepsis is a systemic illness, so they don’t align with the specific notion of a non-neurological cause mimicking stroke.
