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.

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.

Taking longer to get to deep sleep or REM sleep can disrupt memory consolidation and emotional processing, affecting overall rest and cognitive health. And now a recent study makes a shocking link between delayed REM sleep and Alzheimer's disease.

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.

Delays in dreaming might be an early warning sign of Alzheimer's disease. People who take significantly longer to enter the rapid eye movement phase of sleep could be experiencing an early symptom of Alzheimer's, researchers reported Monday in the journal Alzheimer's & Dementia .
