Could that cold sore be a risk factor for Alzheimer's?

A study by British researchers suggests a link between Herpes Simplex Virus and Alzheimer's. Previous research has indicated that many affected by Alzheimer's have a high proportion of the virus in their brain cells, and recent studies show that one of the effects of HPV infection is to increase the proteins known to cause plaques in Alzheimer's patients.

Professor Itzhaki, the lead researcher, suggests that the HPV may account for at least 50% of Alzheimer's cases.
