Alzheimer's disease, Rapid eye movement sleep

Taking longer to get to REM sleep could indicate Alzheimer's disease
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.
Alarming Alzheimer sleep study reveals new risk
Groundbreaking study uncovers the crucial link between REM sleep patterns and Alzheimer's disease, providing new insights for early detection and prevention.
Delayed REM Sleep Could Be an Early Sign of Alzheimer’s
Taking longer to enter the dream phase can disrupt the ability to consolidate memories and interfere with emotion regulation.
New Study Finds Delayed REM Sleep Could Be an Early Warning for Alzheimer’s
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.
Alzheimer's Biomarkers Tied to Delayed REM Sleep
Prolonged rapid eye movement (REM) sleep latency was linked with Alzheimer's disease biomarkers, cross-sectional data showed.
Prolonged REM sleep latency linked to Alzheimer’s disease biomarkers
Research indicates longer REM latency is associated with higher Alzheimer's biomarkers, pointing to its potential as an early indicator of neurodegeneration.
REM Sleep Delays May Indicate Early Alzheimer’s
Summary: Delayed rapid eye movement (REM) sleep may be an early indicator of Alzheimer’s disease. Researchers found that participants with delayed REM sleep had higher levels of toxic proteins associated with Alzheimer’s and reduced levels of brain-derived neurotrophic factor (BDNF), which supports memory.
Delayed Dream Sleep Linked to Alzheimer's Risk
Those with Alzheimer’s were more likely to have delayed REM sleep, and they also had higher levels of the toxic brain proteins associated with the disorder, amyloid and tau. People with delayed REM sleep also had higher levels of the toxic proteins – 16% more amyloid and 29% more tau – than those with early REM sleep, results show.
New research suggests delayed REM sleep may signal Alzheimer's onset in older adults
Scientists have recently shown that both the quality and the amount of sleep we get may influence our risk of developing Alzheimer's disease.
