Educational only
Educational only — acute neurologic deficits require urgent evaluation regardless of suspected mimic.

Do not assume ‘mimic’ until evaluated. Any acute neurologic deficit should trigger local emergency/stroke alert escalation immediately and urgent imaging per protocol.
What you'll learn
- List common stroke mimics
- Identify immediate reversible causes to check (e.g., glucose)
- Recognize why mimics should not delay emergency evaluation
- Use a structured differential while maintaining ‘time is brain’ urgency
Why mimics matter
- Common in acute pathways
- Can be reversible
- But don’t delay stroke workup
Must-check-now items
- Glucose
- Vitals
- Medication list
- Seizure history
Common mimics
- Hypoglycemia
- Seizure/Todd’s
- Migraine
- Functional neurologic disorder
- Toxic-metabolic (electrolytes, infection)
Communication
- Describe findings objectively
- Escalate if uncertain
