Sorry if someone has already posted this. It it sounds very promising.

It be say this:

"Publishing in Science Translational Medicine, the team describes the technique as using a particular type of ultrasound called a focused therapeutic ultrasound, which non-invasively beams sound waves into the brain tissue. By oscillating super-fast, these sound waves are able to gently open up the blood-brain barrier, which is a layer that protects the brain against bacteria, and stimulate the brain’s microglial cells to activate. Microglial cells are basically waste-removal cells, so they’re able to clear out the toxic beta-amyloid clumps that are responsible for the worst symptoms of Alzheimer’s."

Which sound very interesting.  I am not sure it truly opens blood brain barrier as it would otherwise likely cause bleed brain....BUT....shaking up things brain, getting things unstuck, and INCREASING blood flow are ALL beneficial. 

Do you know if they doing this in the USA?? 

Thanks
