Facial stimulation clears brain waste, boosts aging minds

Researchers have discovered a non-invasive method to boost brain waste removal by stimulating facial lymphatic vessels. This technique shows promise for improving cerebrospinal fluid drainage, which declines with age. The study found that gentle mechanical stimulation of the face and neck can significantly enhance cerebrospinal fluid clearance. This method, tested on aged animals, restored youthful CSF flow, offering a potential treatment for age-related cognitive decline. This research builds on previous work mapping brain waste drainage pathways. The team is now investigating how this method can be applied to treat neurological diseases and developing wearable devices for future use.
