“…Complete (apneas) or partial (hypopneas) obstructive events in OSA, resulting in intermittent hypoxaemia, disturb sleep, causing its fragmentation, which is then a condition leading to excessive daytime sleepiness (EDS) (Barbe et al, ; Bucks, Olaithe, & Eastwood, ; Slater & Steier, ; Zhou et al, ). The resulting reduced blood oxygen saturation and disturbed sleep architecture may determine neurocognitive dysfunction and mood disorders in patients with OSA (Bucks et al, ; Jackson, Howard, & Barnes, ; Lal et al, ; Naqvi, Wang, Glozier, & Grunstein, ; Zhou et al, ). Cognitive impairment with OSA is mainly characterized by a lower level of attention and vigilance, reduced learning and memory, and decreased executive performance (Jackson et al, ; Lal et al, ; Rouleau, Decary, Chicoine, & Montplaisir, ; Tulek et al, ; Zhou et al, ).…”
