I haven't been on this board for several weeks as my FIL, who suffered from stroke-related dementia, died a few months ago. However, I still maintain an interest in AD.
Anyway, yesterday there was an article on a new breakthrough in AD treatment announced. It seems when a drug used to treat arthritis was injected in the spine of a few AD patients they showed immediate improvement in brain function within several minutes and it was sustained. The researchers were extremely excited by the finding. The drug is Empril or Epril or something like that and it is already approved by the FDA for arthritis treatment. I think the article was in Science Digest or Science magazine. Sorry I don't have any links to it.
