Sleep Apnea and Cognitive Decline In Seniors

Researchers find there is a connection between Sleep apnea (sleep-disturbed breathing), and dementia.

Sleep Results


Participants with sleep apnea and hypoxemia displayed worse attention spans and slower cognitive ability compared to the control group. Moreover, there is a high correlation between the APOE-ε4 allele protein and significant cognitive and sleep deficits.



The study highlights the potential of using screening and treatment of sleep apnea as a way to reduce risk of dementia, especially in people who carry the APOE-ε4 allele. Clearly,  this condition negatively affects attention, processing speed, and memory.

Especially relevant, this study indicates that providing these screenings and treatment for Seniors is a viable strategy to reduce dementia risk.
