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.

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.

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

Prolonged rapid eye movement (REM) sleep latency was linked with Alzheimer's disease biomarkers, cross-sectional data showed.

Scientists have uncovered a potential link between delayed REM sleep and Alzheimer's disease. A new study shows that individuals who take longer to enter the dream phase of sleep may be at higher risk of developing the condition.

Taking longer to enter the dream phase can disrupt the ability to consolidate memories and interfere with emotion regulation.

It usually takes each cycle of sleep 90 minutes or more to complete. The study, which involved 128 participants with mixed dementia and dementia-free status, found that people wit

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

A study suggests delayed REM sleep could indicate early Alzheimer's, showing increased amyloid clumps and tau tangles in the brain, and reduced brain-derived neurotrophic factor. Researchers argue this disruption in the dreaming phase may contribute to memory impairment,
