DESIGNECOLOGIST on Unsplash If you snore you should probably make sure you don’t have obstructive sleep apnea (OSA). In this study below OSA severity was associated with Alzheimer’s disease pathology burden in the hippocampus the region of the brain responsible for memory. These results indicate that OSA may account for some of the “cognitively normal” individuals who have been found to have substantial amyloid burdens, and are currently considered to be at a prodromal stage of AD. The implications of this and other studies linking sleep deprivation to Alzheimer’s disease and dementia are profound and imply that sleep hygiene and preventing sleep disorders may be a strategy to reduce the lifetime risk and incidence of dementia. Sleep is critical for the brain to clear itself of protein debris and if you have insufficient sleep the debris accumulates, for example, amyloid plaques associated with Alzheimer's disease. OSA and other sleep disorders may therefore bring forward the AD ...
