JediJeremy writes "Naturehas this article on the possibility that researchers have identified the cause of Alzheimers. Their research says that amyloid beta, a protein in the brain, may cause plaques and makes an enzyme -BACE1-that causes dimentia. In the study mice, those without BACE1 did not get dimentia, while the others did. The article also says that there are current market drugs that can stop BACE1 production and all that needs to be done is for a human trial to begin. Looks like there is hope for those that suffer."
