New research shows how the depth of sleep can impact our brain’s ability to efficiently wash away waste and toxic proteins. Because sleep often becomes increasingly lighter and more disrupted as we become older, the study reinforces and potentially explains the links between aging, sleep deprivation, and heightened risk for Alzheimer’s disease.
«Sleep is critical to the function of the brain’s waste removal system and this study shows that the deeper the sleep the better,» said Maiken Nedergaard, M.D., D.M.Sc., co-director of the Center for Translational Neuromedicine at the University of Rochester Medical Center (URMC) and lead author of the study. «These findings also add to the increasingly clear evidence that quality of sleep or sleep deprivation can predict the onset of Alzheimer’s and dementia.»
The study, which appears in the journal Science Advances, indicates that the slow and steady brain and cardiopulmonary activity associated with deep non-REM sleep are optimal for the function of the glymphatic system, the brain’s unique process of removing waste. The findings may also explain why some forms of anesthesia can lead to cognitive impairment in older adults.

Sin duda, ya ha visto antes – las listas que promueven el asombroso poder curativo del vinagre de sidra de manzana para un asombroso número de enfermedades. El “VSM” (como se nombra en algunos estudios) ha sido elogiado por su capacidad para balancear su pH, aumentar las bacterias intestinales buenas y ayudar a controlar su peso, así como muchas otras cosas beneficiosas.
At the dawn of the 19th century, when Paolo Mascagni hired Clementi Susini to help him make wax models of the human lymphatic system including the brain, he probably had no idea he was setting himself up for centuries of ridicule.
