Boiling Bubbles in the Brain for Alzheimers

Using the theory that the border between the blood circulation and the brain (called the blood brain barrier) may prevent removal of toxic amyloid proteins which may cause Alzheimer's, researchers have tried an innovative technique.

In mice bred to develop this, the injected micro-bubbles then use ultrasound to heat them up and "loosen" this barrier.

They found that treated mice had decreased levels of amyloid and improved memory.

Although still a long way from human trials, I found this fascinating and wonder

how they ever even thought of it!
