A new study shows rapid eye movement (REM) sleep and Alzheimer’s disease.
A study from China published in the Journal of Alzheimer’s Disease and Journal of Dementia by the Alzheimer’s Disease Association analyzed the sleep cycles of 128 adults in a variety of cognitive conditions.
This study found that the highest occurrence of REM latency is associated with the highest risk of Alzheimer’s disease if it takes a long time to reach the first REM period after someone has fallen asleep.

The researchers concluded that Long-term Rem delays It may serve as a “new marker of risk factors” for Alzheimer’s disease and related dementia.
Dr. Wendy Troxel, a senior behavioral scientist at Land Corporation of California, said the study adds to the “expanding evidence” that certain sleep features, such as long-term REM sleep, are associated with biomarkers of Alzheimer’s disease.
“Dreams are mostly the stages of sleep when dreams occur and are extremely important for memory integration and emotional processing,” Utah-based Troxel is also the author of “Share Cover: A Guide to All Couples for Couples,” told Fox News Digital.
This new study is consistent with findings from Troxel’s own lab. This indicates that there are poor signs of poor sleep health, such as short sleep health and poor quality. Cognitive function.

“Sleep confusion can contribute to the accumulation of amyloid and tau proteins, a major feature of Alzheimer’s pathology,” a sleep expert said.
“However, it is also important to note that the Alzheimer’s disease process itself can disrupt sleep, suggesting a two-way link between sleep problems and cognitive decline.”
Dr. Julio Talialatera, Vice President and Institute Director of the Brain Health Research Institute at the University of Texas Medical, responded to these findings in another interview with Fox News Digital.
Taglialatela said it was “long understood.” good night It is associated with a lower risk of developing dementia.
“Our brains use sleep to remove toxic proteins, similar to those associated with Alzheimer’s. These results indicate that the washing mechanism is less effective when it takes longer to enter the REM cycle,” he pointed out.
“Unfortunately, there’s nothing an individual can do to control how long it takes to enter REM sleep,” the experts.
However, experts said the findings provide a “promising path” to predict whether someone will ultimately develop dementia.
“Early interventions for Alzheimer’s disease are essential to slow progression, and REM sleep measurements can be a marker of who is who. Treatment candidates Even before they began to show impaired cognitive function,” Talia Latera said.
The study had several limitations, and the researchers acknowledged that it was primarily cross-sectional.
The sample size was also relatively small, and researchers focused only on one specific type of tau protein.

Researchers also pointed out that monitoring sleep in a clinical setting could introduce “environmental disorders,” which could affect the accuracy of sleep measurements. “Future research will benefit from research in a real-world home environment,” they wrote.
These findings are important, but Troxel said it encourages individuals to not make information “another source of worry that keeps them waking up at night.”
“Avoid the tendency to be overly locked into metrics such as REM sleep rates and delays from consumer sleep trackers because they have limited accuracy in determining sleep architecture,” she warned. “You can get hooked on such data It raises anxietythis is a powerful sleep disruptor. ”
The best approach is Good sleep healthsaid the expert.
According to Troxel, adults should strive for 7-9 hours of Shuteye, maintaining consistent sleep and wake time.
“Minimize common destructors such as excess caffeine and alcohol, known to fragment REM sleep fragments. [as well as] Using screens before bedtime,” she added.

“Focusing on these core sleep habits is Brain and overall health. ”
Taglialatela also encourages maintaining “good bedtime habits” and reducing the risk of developing Alzheimer’s disease, while focusing on creating a “good sleep environment.”
