Cold sores and Dementia

a study found that people who get cold sores have a greater risk of developing Alzheimers [dementia]

Cold sores are from the HSV1 virus.

Once again, a connection of disease to viruses.

AS you might know, I think that most of the "mysterious diseases" [that do not have a well known cause or cure] are due to these critters...

And therefore a good strong immune system is important, even VITAL... and immunity starts in our gut with microflora ["friendly bacteria".
