Obstructive sleep apnea severity is linked to amyloid burden in cognitively normal elderly individuals.

“If you'd like to learn more about how apnea can negatively impact cognition, there's an excellent paper that was published on this in 2018. The first author is Sharma, S-H-A-R-M-A. It should be easy to find. The title of the paper is "Obstructive Sleep Apnea Severity Affects Amyloid Burden In Cognitively Normal Elderly". This was a longitudinal study. Amyloid burden is a correlate of Alzheimer's and other forms of neurodegeneration and cognitive decline associated with memory deficits.”
