If a patient develops new or worsening stroke symptoms, reduced consciousness, seizure, severe headache, airway/swallowing danger, or unstable vital signs, activate emergency response and follow local stroke escalation protocols.

Key takeaways

  • Recognize PCA stroke symptoms (visual field loss)
  • Explain safety risks (driving, bumping, falls)
  • Know why some people experience visual hallucinations
  • Ask for practical vision rehab and home adaptation steps
