How do we clean out our brain of waste? 

Edit: Just says they boosted the lymphatic system of the mice, doesn't say how. If you give "strengthen lymphatic system" a Goog you get physical exercise, hydration and healthy diet.

They boosted the lymphatic system by using an experimental treatment that causes the brain to overexpress vascular endothelial growth factor. The increase in this factor then causes the expansion and growth of lymphatic vessels. This treatment is not possible in people.
