Sleep apnea (sleep apnoea or sleep apnœa in British English) is a sleep-related breathing disorder in which repetitive pauses in breathing, periods of shallow breathing, or collapse of the upper airway during sleep results in poor ventilation and sleep disruption.
About 936 million adults around the world have sleep apnea. ... if sleep apnea affects the brain health and increases the risk for dementias, then treatment of it can serve as a strategy to ...
Obstructive sleep apnea does occur even more frequently in people with Down syndrome than in the general population. A little over 50% of all people with Down syndrome experience obstructive sleep apnea, [59] and some physicians advocate routine testing of this group. [60]
Sleep deprivation is a significant societal problem. It is estimated that around 35.2% of all adults in the US sleep less than 7 hours. [3] Lifestyle choices, health conditions, and the use of stimulants are examples of some of the causes that underlie sleep deprivation in humans. Sleep deprivation is known to cause metabolic changes, such as ...
By the end of this century, warmer temperatures will cost humans an average of 50 to 58 hours of sleep per person per year, according to a new study in the journal One Earth. That works out to a ...
The respiratory disturbance index (RDI)—or respiratory distress Index—is a formula used in reporting polysomnography (sleep study) findings. Like the apnea-hypopnea index (AHI), it reports on respiratory distress events during sleep, but unlike the AHI, it also includes respiratory-effort related arousals (RERAs). [1]
Obstructive sleep apnea has shown to influence cognitive function in both children and adults. [50] Other sleep disorders also present a higher risk for academic failure: 22% of those with insomnia, 21% with restless leg syndrome/periodic limb movement disorder, [51] 26% with circadian rhythm sleep disorder, and 21% with hypersomnia.

When sleep-deprived, PCC activity decreases, impairing selective attention. Subjects were exposed to an attention-shifting task involving spatially informative, misleading and uninformative cues preceding the stimuli. When sleep-deprived, subjects showed increased activation in the left intraparietal sulcus. This region is activated when ...
