The virus behind cold sores is a major cause of the insoluble protein plaques found in the brains of Alzheimer's disease sufferers, University of Manchester researchers have revealed.

They believe the herpes simplex virus is a significant factor in developing the debilitating disease and could be treated by antiviral agents such as acyclovir, which is already used to treat cold sores and other diseases caused by the herpes virus. Another future possibility is vaccination against the virus to prevent the development of the disease in the first place.
There seems to be some major advancements in regards to this disease more and more each day... its great news. When I was growing up, my parents took care of one of my great aunts who was dying of alzheimer's... she lived with us for a long time. One of the scariest things I have ever seen... I really hope to see the day when this disease is gone forever.
