As the primary examine in a collection known as the Sleep and Dementia Consortium, this analysis regarded into what markers of sleep have been related to higher cognition. Earlier than conducting the examine, researchers suspected that the proportion that individuals spent in deeper sleep phases like stage 3 and REM can be most necessary for mind operate.
Nevertheless, after crunching the numbers, they discovered that higher “sleep consolidation” and an absence of sleep apnea have been truly the metrics most related to higher cognition. These have been much more necessary than sleep stage percentages—beforehand thought of gold normal metrics for sleep high quality.
This discovering will lay the groundwork for future analysis untangling the nuances of how sleep impacts the ageing mind. Sleep and Dementia Consortium researchers predict that, “Sleep of ample high quality and length could also be related to decreased threat of dementia by a number of mechanisms, together with augmenting the glymphatic clearance of Alzheimer’s illness proteins.”
These preliminary findings present the significance of monitoring and treating sleep apnea, in addition to engaged on sleep consolidation, with the intention to keep mentally sharp.
