1 Μαρ 2022 · Untreated OSA is associated with cognitive impairments and problems with mood, memory, and alertness. Researchers believe that sleep apnea may cause brain damage due to the long-term effects of chronic sleep deprivation, as well as oxygen deficiency and the breakdown of the blood-brain barrier.
18 Ιαν 2024 · Severe obstructive sleep apnea often associated with sleep fragmentation, reduced N3 and REM sleep, and hypoxemia. Alternative metrics, such as sleep apnea–related hypoxic burden, arousal intensity, sleep apnea–related heart rate changes are emergent predictors of heart disease and mortality. Central sleep apnea
13 Αυγ 2012 · If sleep apnea (reported by subject or partner), daytime sleepiness, and obesity were also present, the odds ratio increased to 8.0 (95% CI, 1.07 to 356.1). Palomaki concluded that snoring could be a risk factor for ischemic stroke, likely because of the higher prevalence of OSA among snorers.
Obstructive sleep apnea (OSA) is accompanied by structural brain changes, as shown by neuroimaging findings from several groups. These neural changes likely contribute to central nervous system dysfunction in OSA, including psychological and physiologic comorbidities.
14 Απρ 2015 · Obstructive sleep apnoea is increasingly recognised as one of the potentially modifiable risk factors for dementia; its multiple effects on the central nervous system are acknowledged, although their nature and prognosis are yet to be fully understood. •.
8 Σεπ 2014 · Results show that participants with severe, untreated sleep apnea had a significant reduction in white matter fiber integrity in multiple brain areas. This brain damage was accompanied by impairments to cognition, mood and daytime alertness.
The brain responds to the lack of oxygen by alerting the body, causing a brief arousal from sleep that restores normal breathing. This pattern can occur hundreds of times in one night. The result is a fragmented quality of sleep that often produces an excessive level of daytime sleepiness.
