Sleep apnea is a primary cause of excessive daytime sleepiness due to airway collapse disrupting restorative sleep stages as described in [1], and the two conditions are frequently comorbid in specific patient populations such as those with end-stage renal disease [2]. Furthermore, the presence of both conditions is used as a clinical marker to identify higher-risk subgroups in mortality studies [3].

measurementRestless legs syndrome (RLS), periodic limb movement disorder, sleep apnea, and excessive daytime sleepiness affect up to 70 percent of patients with end-stage renal disease receiving hemodialysis.

claimWhile studies of patients at sleep clinics tend to show an association between sleep apnea and mortality, most population-based studies have failed to find such an association, with the exception of a subgroup of patients under age 60 with both snoring and excessive daytime sleepiness, who experienced twice the risk of mortality.

claimIndividuals with sleep apnea experience airway collapse in deeper sleep states, which reduces time spent in stage N3 and REM sleep, leading to excessive daytime drowsiness.
