Posterior circulation stroke can be subtle but high-risk. If suspected (sudden severe dizziness, ataxia, double vision, new weakness, dysarthria): activate local stroke alert/emergency response and document last known well time.
Key takeaways
- Identify posterior circulation presentation patterns
- Explain why isolated dizziness can still be stroke
- Identify high-risk deterioration patterns (brainstem/cerebellar)
- Describe airway/swallow escalation themes
Common patterns
- Vertigo + neuro deficits
- Diplopia
- Dysarthria/dysphagia
- Ataxia
- Crossed signs
Why it’s missed
- Mimics
- Normal early imaging limitations in some cases
- Anchoring bias
High-risk deterioration themes
- Decreased LOC
- Airway compromise
- Progressive brainstem signs
Escalation priorities
- Urgent imaging/consult
- NPO until swallow safety confirmed
