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.

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.

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

Study showed that patients who took longer to reach the dream state also had more biomarkers for the disease.

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,

People who take longer to start the dream phase of sleep may be experiencing an early symptom of Alzheimer's disease.
