Many people with CMT report having problems with breathing.
A few weekends ago, I listened to the HNF webinar on COVID-19 and CMT with Dr. John Bach of Rutgers University Medical School, a leader in the field of pulmonary rehabilitation, particularly for people with neuromuscular diseases. You can watch it and get a bunch of other materials now — for free — thanks to the HNF.
Science is starting to confirm very wide ranging effects to the nerve damage CMT does, often slowly and over time so it may not be very noticeable for many years.
Some recent studies on obstructive sleep apnea got attention for concluding something fairly obvious — losing weight and reducing fat in the tongue might be the best treatment for OSA.
Earlier in life, relatively healthy people with CMT can overlook signs of compromised respiratory function which will start to cause more and more problems for them later.
