I recently read in a reply by SCI nurse KLD that the existence of sleep apnea among individuals with SCI is higher than the public at large. Is there research that discusses what the link is between SCI and sleep apnea? I, for one, realize that I periodically awake, gasping for air. In addition, I have excesive tiredness during the day, but thankfully, no headaches like those reported to be common with sleep apnea. I'm going to pursue a sleep evaluation if I can.
