Sleeping on one's side, as opposed to other positions such as on one's back or stomach may more effectively remove brain waste, reducing the chances of developing Alzheimer's, Parkinson's and other neurological diseases, scientists have found.Researchers at Stony Brook University used dynamic contrast magnetic resonance imaging (MRI) to image the brain's glymphatic pathway, a complex system that clears wastes and other harmful chemical solutes from the brain.
Researchers Hedok lee, Helene Benveniste, discovered that a lateral sleeping position, or side position, is the best position to most efficiently remove waste from the brain. The buildup of brain waste chemicals may contribute to the development of Alzheimer's disease and other neurological conditions. Benveniste, Principal Investigator and a Professor in the Departments of Anesthesiology and Radiology at Stony Brook University School of Medicine, has used dynamic contrast MRI for years to examine the glymphatic pathway in rodent models.
