However, some research suggests that poor sleep could raise your risk of Alzheimer’s. A study published in November found that 35 percent of people who were considered poor sleepers (and felt excessively tired during the day as a result) went on to develop motoric cognitive risk syndrome (MCR), which is considered a precursor to dementia.

A delay in getting to the rapid eye movement (REM) stage of sleep may be linked to Alzheimer's disease and related dementias, a new study indicates.

Groundbreaking study uncovers the crucial link between REM sleep patterns and Alzheimer's disease, providing new insights for early detection and prevention.
