Summary

Charcot-Marie-Tooth disease (CMT) can cause respiratory issues like central sleep apnea due to diaphragmatic weakness. This emphasizes the importance of recognizing respiratory muscle dysfunction in CMT patients.

Area of Science:

  • Neurology
  • Pulmonology
  • Clinical Medicine

Background:

  • Charcot-Marie-Tooth disease (CMT) is a progressive hereditary neurological disorder.
  • Respiratory complications are increasingly recognized in advanced stages of CMT.
  • Phrenic nerve involvement can lead to diaphragmatic dysfunction.

Observation:

  • A 61-year-old male patient with a 44-year history of CMT presented with respiratory complaints.
  • The patient exhibited diaphragmatic weakness attributed to phrenic nerve disturbance.
  • Central sleep apnea and hypopnea were observed during REM sleep.

Findings:

  • Diaphragmatic weakness in CMT patients can lead to central sleep apnea and hypopnea.
  • Inhibition of accessory inspiratory muscles was noted in conjunction with diaphragmatic weakness.

  • The study highlights a specific case of respiratory dysfunction in long-standing CMT.

    • Implications:

    • Respiratory muscle dysfunction, particularly diaphragmatic weakness, is a significant concern in Charcot-Marie-Tooth disease.
    • Early recognition and management of respiratory issues are crucial for improving patient outcomes.
    • Further research is warranted to understand the full spectrum of respiratory complications in CMT.
