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 Broca-type expressive aphasia patterns
  • Differentiate aphasia from dysarthria (speech muscle weakness)
  • Explain how MCA branch territory relates to language symptoms
  • Know what CT/MRI/CTA can show and what to ask about localization

Key takeaways

  • Recognize Broca-type expressive aphasia patterns
  • 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.
