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.
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.
Studies show CMT tends to come with Disturbed Sleep, Depression, and Reduced Quality of Life. 😞
This post summarizes the scientific research I've absorbed on the subject of CMT and sleep apnea. It's definitely accurate relative to my own experience in the past year or so.
