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.

Scientists have recently shown that both the quality and the amount of sleep we get may influence our risk of developing Alzheimer’s disease. Now, a study suggests that people who take significa

In a nutshell Taking longer than 193 minutes to enter REM sleep may indicate elevated levels of proteins associated with Alzheimer’s disease, potentially serving as an early warning sign of brain changes.
