That's not true, it's been shown to be reversible with ultrasound dissolving the plaque build up. ( http://stm.sciencemag.org/content/7/278/278ra33 )

The plague serves a primary purpose of regulating voltage between neurons like a buffer, but now according to this study it looks like it serves a secondary purpose like an immune reaction to disease but it gets out of control and causes alzheimers, so removing the plaque cures the alzheimers but that's not getting the underlying cause which this study says is the disease.

It's fantastic research and hopefully will provide a lot of hope to people and their familes suffering from it.

The mechanism claims to be that the SUS merely selectively opens the blood-brain barrier long enough for microbubbles to pass through, implying (as I read it) that their action is mechanical.

It still does not bring back the neurons already dead.

That's not necessarily true. It would presumably depend on how much damage was done. Here's some cases of improvement with turmeric, one of the spices in curry that has anti bacterial and anti fungal properties http://www.greenmedinfo.com/blog/turmeric-produces-remarkabl...

You're not exactly linking to the type of source you'd want to read for trustworthy scientific information. Unless your version of science says fluoride in drinking water is killing you, eating greens will cure cancer, and GMO's are horrible.

That's true though it's still interesting the three patients cited in the paper they reference improved. Here are some better links perhaps

This is why Steve Jobs died so early, this thinking right here.
