The glymphatic system clears brain waste during sleep
Scientists reveal how the brain's waste-removal system functions during sleep through slow electrical waves aiding fluid movement. Disruptions may relate to Alzheimer's and Parkinson's. Research aims to enhance treatments and prevention.

Scientists have recently made significant progress in understanding the brain's waste-removal system. Two teams of researchers have published papers in the journal Nature detailing how the brain clears waste during sleep. They found that slow electrical waves push fluid around brain cells, allowing waste products to be absorbed into the bloodstream and eventually removed from the body. This process, known as the glymphatic system, plays a crucial role in maintaining brain health. The studies suggest that disruptions in this system could be linked to neurodegenerative disorders like Alzheimer's and Parkinson's. By better understanding how the brain cleans itself, researchers hope to develop new treatments and preventive measures for a range of brain disorders. Further research is needed to confirm these findings in humans, but the implications of these studies could have far-reaching effects on our understanding of brain health and disease prevention.
