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.

Research indicates longer REM latency is associated with higher Alzheimer's biomarkers, pointing to its potential as an early indicator of neurodegeneration.
