Boosting brain’s waste removal system improves memory in old mice | Researchers found that rejuvenating the lymphatic vessels in the brain enhanced recognition memory and restored synaptic function through an interleukin-6 (IL-6) pathway.

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.

Adequate sleep and exercise are two good ways to improve lymphatic drainage.

I remember seeing a video of a scan of someone in REM. The brain was flushing/washing itself with cerebrospinal fluid whilst the person being scanned was asleep.

First stage was blood draining from the brain and then the fluid washed in and out in waves to clear some of the accumulated “debris?”.

Our bodies are incredible.

Wow very cool video! Thanks for sharing!
