In the first study, researchers at Harvard Medical School studied more than 2,800 individuals ages 65 and older participating in the National Health and Aging Trends Study to examine the relationship between their self-report of sleep characteristics in 2013 or 2014, and their development of dementia and/or death five years later. Researchers found...
What's new here is that inadequate sleep in midlife raises one's risk of dementia. There are many reasons for poor sleep in middle age: shift work, insomnia, caretaking responsibilities, anxiety, and pressing deadlines, just to name a few. Although not all of these are controllable, some are. For example, if you're currently only sleeping four to f...
Although it is not totally understood why inadequate sleep increases your dementia risk, one possible reason relates to the deposition of the Alzheimer's protein, beta amyloid. Beta amyloid is the protein that clusters and clumps together to form Alzheimer's plaques. No one is completely certain what its normal function is, although there is increa...
The good news is that you can reduce your risk of developing dementia by getting adequate sleep. One studyfrom researchers in Toronto and Chicago examined people who were at increased genetic risk of developing Alzheimer's. They found that better sleep not only reduced the likelihood of developing clinical Alzheimer's disease, but it also reduced t...
Sleep isn't merely an annoying interruption between the important aspects of our waking lives. Just like eating right and exercising, sleep is absolutely essential for good brain health. These two new studies show that the harmful effects of inadequate sleep can start at age 50 (if not earlier), and they can lead to early dementia and death. But th...

May 6, 2024 · People with dementia may experience increased daytime sleepiness and cognitive impairment. Loss of brain function disrupts the regulation of sleep-wake cycles. Dementia often changes sleep patterns, impacting both individuals with dementia and their caregivers. Behavioral strategies and a sleep routine may help manage sleep issues related to ...
Frequent manifestations of sleep disturbances in persons with AD include day-night sleep pattern reversals, frequent nighttime awakenings, increases in daytime sleep, and decreases in slow-wave sleep and rapid eye movement sleep (Bliwise, 2004). Studies that used global measures of cognition have reported that fragmented sleep increases in concert with severity of dementia.

Objectives To conduct an updated systematic review and meta-analysis of association between sleep and all-cause cognitive disorders. Methods PubMed and EMBASE were searched from inception to 18 February 2019. Cohort studies exploring longitudinal associations of sleep with cognitive decline or dementia were included. The multivariable-adjusted effect estimates were pooled by random-effects ...
