Stimulation clears brain waste, benefiting aged mice

Scientists have discovered a non-invasive method to improve brain waste removal, potentially aiding in the treatment of age-related neurological disorders. This involves stimulating lymphatic vessels. Researchers found that stimulating facial and neck lymphatics enhances cerebrospinal fluid flow, which clears brain waste. This was achieved using a mechanical stimulator on aged mice, restoring youthful drainage levels. This new technique could lead to wearable devices to enhance brain waste clearance. The team is now studying its effects on diseases like Alzheimer's and its potential therapeutic applications.
