Research suggests that improving the brain's waste removal system, specifically the meningeal lymphatics, can restore memory function in aging mice. This approach, which targets vessels outside the brain, has the potential to offer new therapies for age-related cognitive decline by enhancing the body's natural cleaning process. The study also found that this treatment reduced levels of the inflammatory protein IL-6, which is linked to impaired neuronal signaling and memory loss. Ultimately, supporting the health of the brain's drainage pathways could be key to preserving or restoring cognitive abilities.
