Thanks for posting. That's an interesting article. How weird that there may be a link between cognition & herpes simplex virus I in bipolar patients. I've had HSV-I since I was a child. I got the worst cold sores & fever blisters, and I didn't even ever need braces. Sometimes, as an adult, it got so bad, my PCP would call in Valtrex for me. Lately, it seems to be lying low. I surprisingly have not had issues with it in a few years, which is odd now that I think about it. Of course, now I'll probably wake up with a cold sore tomorrow
