The Role of Herpes in Alzheimer's

When you get a virus, a bacteria, any foreign microbe going through the brain, it turns on the immune system. And when that immune system in the brain is turned on in a self-defense mode, beta amyloid is produced as part of the immune system and starts targeting brain cells.

But certainly, if one of the risk factors for Alzheimer's is things that turn on the immunesystem in the brain then that is a reasonable worry.
