A new study found a link between cytomegalovirus (CMV) and Alzheimer's disease. Here's what a neurologist wants you to know, plus how to protect yourself.

Researchers have discovered a link between a chronic gut infection caused by a common virus and the development of Alzheimer's disease in some people. Most people encounter cytomegalovirus (CMV) during childhood, and after the initial infection the virus remains in the body for life, usually dormant.

Scientists have long wondered about the mysterious origins of Alzheimer’s disease, with its hallmark protein tangles and plaques that slowly devastate the brain’s ability to form memories and function normally.

If the findings are validated by further research, existing antiviral drugs could be tested to treat or prevent this form of Alzheimer’s disease. This can be supported by a bloo
