Could Alzheimer’s be Triggered by Herpes Virus?

Results from a major analysis of genetic and molecular networks in the brains of Alzheimer’s disease (AD) patients have suggested a role for two human herpesvirus species. The study, headed by a team at the Icahn School of Medicine at Mount Sinai, found increased levels of the two Roseoloviruses , human herpesvirus 6A (HHV-6A) and human herpesvirus 7 (HHV7), interacting with gene networks in areas of the brain that are known to be affected in AD. While the researchers are not claiming that
