This sounds like a possible key to my family's Alzheimer's. While going downhill rapidly with Alzheimer's, my father died of sudden kidney failure in one week due to an Epstein-Barr infection, that he had had chronically throughout his life. Epstein-Barr is also in the herpes family, and is know to be able to enter and infect every organ in the human body. I was diagnosed with Chronic Active Epstein-Barr after multiple infections in multiple organs throughout my life, including a bout of mono that infected my brain and gave me meningitis when I was very young. It's a family problem for sure! Our family Alzheimer's killed everyone in my dad's family, so it is equally scary and it's a faster type of Alzheimers than the usual kind. When I saw this herpes simplex research in the science news a while back, I began wondering if recurring EBV herpes infections might be the ultimate cause of our Alzheimers. They still know very little about EBV in the USA. In Asia it is much more common (my father's family is from Asia), and much of the research is coming from Japan and other Asian countries. I used to be worried about taking anti-virals for my EBV and avoided them, but this research has made me change my thinking. I've started taking a round of Valacyclovir once a month to knock down any EBV that is kicking up, and I guess I'll be a bit of a guinea pig to see if it can also help prevent my family Alzheimer's. I'm also doing the full Bredesen protocol, so I'll never really know which worked if they do work, but I can't help wondering if our slightly different form of Alzheimer's isn't an EBV herpes induced form?
