What if your brain has a hidden waste-removal system?
Scientists in South Korea may have uncovered an important piece of a 250-year-old mystery.
New research has identified tiny openings around the brain that appear to help drain cerebrospinal fluid toward the body’s lymphatic system.
Why does this matter? Researchers are exploring how the brain clears waste and whether disruptions in this process may play a role in conditions like Alzheimer’s and other neurodegenerative diseases.
It’s not a treatment or cure, but it could be an important step toward better understanding the aging brain.
