# Can the brain's deep-cleaning system be harnessed to prevent Alzheimer's?

New Scientist examines whether the brain's glymphatic system, which flushes waste products such as amyloid from the brain mainly during sleep, could be targeted to prevent Alzheimer's disease. The report weighs emerging research on boosting this cleaning process against unanswered questions about whether it can actually delay or avert dementia. The idea matters because it points to sleep and lifestyle-based prevention strategies rather than treatments given only after symptoms appear.
