Pontine strokes and ‘locked-in’ risk — basilar artery territory, detection, and communication safety (Advanced)

Advanced course: the pons contains critical motor pathways and cranial nerve systems. Large basilar territory strokes can cause severe paralysis with preserved awareness. Learn detection strategy and emergency questions.

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 pontine stroke patterns (severe weakness, eye movement, swallowing)
  • Explain the concept of locked-in syndrome at a high level
  • Explain imaging strategy: CT for bleed, CTA for basilar occlusion, MRI DWI for early infarct
  • Learn communication safety steps (yes/no eye code) and caregiver advocacy questions

Key takeaways

  • Recognize pontine stroke patterns (severe weakness, eye movement, swallowing)
  • Advanced stroke care requires reconciling the clinical syndrome with timing, imaging, medication risk, patient context, and local pathway capacity.
  • A safe plan names escalation thresholds, responsible clinicians, patient-facing instructions, and the next step if results or symptoms change.
