Researchers Confirm Human Brain's Waste-Clearing Pathways

A new study visualizes the glymphatic system in humans, potentially impacting Alzheimer's research and treatment.

Scientists have used advanced MRI techniques to map the glymphatic system in living human brains for the first time.
The study involved injecting a tracer into patients undergoing brain surgery, allowing researchers to track cerebrospinal fluid movement.
This system helps clear waste proteins like amyloid and tau, which are linked to Alzheimer's disease and dementia.
The findings support the idea that quality sleep may enhance the brain's waste-clearing functions, potentially reducing dementia risk.
Future research may explore lifestyle changes and medications to improve glymphatic function and brain health.
