Conduction aphasia and the arcuate fasciculus — repetition problems and how MRI localizes disconnection (Advanced)

Advanced course: how a ‘disconnection’ between language comprehension and production networks can impair repetition. Learn what it looks like, how it differs from Broca/Wernicke patterns, and how MRI helps localize.

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 conduction aphasia patterns (disproportionate repetition difficulty)
  • Explain the arcuate fasciculus concept at a high level
  • Differentiate from Broca/Wernicke aphasia clinically
  • Explain how MRI localizes cortical vs white-matter disconnection injuries

Key takeaways

  • Recognize conduction aphasia patterns (disproportionate repetition difficulty)
  • 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.
