A groundbreaking discovery suggests that a simple face and neck massage could help the brain stay cleaner and healthier. Researchers at the Korea Advanced Institute of Science and Technology have identified a network of tiny lymphatic vessels just beneath the skin in the face and neck of mice and monkeys. These vessels drain cerebrospinal fluid (CSF), which removes harmful proteins such as beta-amyloid, a major contributor to Alzheimer’s and Parkinson’s.
Previously, scientists believed these vessels were located deep in the neck, making them hard to stimulate. But with special dyes and a new type of anesthesia, they found them much closer to the surface. To test their function, the team created a small device that gently stroked the animals’ faces and necks. Just one minute of this massage boosted CSF flow by nearly three times, with older mice showing fluid movement similar to young mice.
Early tests in monkeys reveal similar promise, and researchers have even identified comparable vessels in human cadavers. While more studies are needed, including trials in Alzheimer’s models, this gentle, non-invasive method could one day help people reduce brain waste buildup, potentially slowing age-related decline and lowering disease risk.
