Classification should not delay acute care. If a patient has new or worsening neurologic deficit: activate local stroke alert/emergency response and proceed with urgent evaluation/imaging per protocol.
What you'll learn
- List major ischemic stroke etiologic categories
- Map common tests to etiologic categories
- Explain how classification supports secondary prevention planning
Categories
- Large artery atherosclerosis
- Cardioembolism
- Small vessel occlusion
- Other determined cause
- Undetermined/cryptogenic
Workup mapping
- Vascular imaging → large artery
- Rhythm monitoring/echo → cardioembolic
- MRI pattern + risk factors → small vessel
Common pitfalls
- Multiple possible causes
- Incomplete monitoring
