Sleepiness due to obstructive sleep apnea

Sleepiness due to obstructive sleep apnea is a neurobehavioral manifestation characterized by an inability to maintain wakefulness and alertness during major awake hours

Sleepiness due to obstructive sleep apnea is a neurobehavioral manifestation characterized by an inability to maintain wakefulness and alertness during major awake hours, occurring secondary to chronic sleep-disordered breathing

Predominantly affecting adults, it results from recurrent episodes of partial or complete upper airway collapse during sleep, which trigger frequent microarousals, sleep fragmentation, and intermittent nocturnal hypoxemia This repetitive sleep disruption and associated neurochemical dysregulation in wake-promoting pathways lead to persistent diurnal somnolence, neurocognitive impairment, and reduced functional capacity, which may persist even in patients receiving primary airway therapies
