Unclogging the brain's 'drain' enhances Alzheimer's meds
Some investigational Alzheimer’s disease therapies are more effective when paired with a treatment geared toward improving drainage of fluid—and debris—from the brain, according to a study in mice. Experimental Alzheimer’s drugs have shown little success in slowing declines in memory and thinking, leaving scientists searching for explanations. The new findings in the journal Nature, however, suggest that the brain’s drainage system—known as the meningeal lymphatics—plays a pivotal but underappreciated role in neurodegenerative disease, and that repairing faulty drains could be ...
