I didn't see it but have read in the last week or so about the ultrasound waves aiding in plaque/tau reduction. What I had read had come out of West Virginia University where Bryostatin and Alkon had done much of their research so it could be a promising avenue. All that is dependent on how big of a problem plaque really is, which of course it up for debate. It's certainly interesting to follow and hopefully makes the anti-plaque drugs more effective with less side effect.
