This item from ScienCentral gives a good introduction to the latest research in the fight against Alzheimer's (and plenty of good references). We often point to the successes of cancer research as the model for the future of aging research - but Alzheimer's research is also a good example. Once public support and awareness comes to a tipping point, real funding and real progress starts. The tipping point for Alzheimer's was probably only a decade ago - amazing progress has been made since then. Just imagine the results if this mighty engine of science were turned to unraveling and preventing aging itself!
