Researchers at the Korea Advanced Institute of Science and Technology have discovered a network of lymphatic vessels just beneath the skin of the face and neck in mice and monkeys and even in human cadavers. These vessels help drain cerebrospinal fluid (CSF), which clears harmful brain proteins like beta-amyloid linked to Alzheimer’s and Parkinson’s. Previously thought to be buried deep in the neck, they were found closer to the surface, making them easier to stimulate. Using a device that gently stroked the face and neck, scientists tripled CSF flow in mice within a minute, restoring older mice’s brain fluid movement to youthful levels. Early monkey tests show similar promise, hinting at a simple, non-invasive way to support brain health and possibly slow age-related decline.
