I've come across yet another article about the link between HSV1 (the 'cold sore virus) and Alzheimer's disease:
It's more recent than some of the other research I've seen and posted about. And the researchers seems pretty 'upfront' about the link.
For new readers, if you wish to see several past posts on this important topic, you can do so simply by putting the word 'herpes' into the search box (top left).
For the avoidance of doubt, nobody anywhere is suggesting that all Alzheimer's disease is caused by the herpes virus.
