Earlier this month, we described a study demonstrating a link between the presence of certain herpes viruses in the brain, and the presence of Alzheimer’s signs. Interestingly, three more studies of this connection have appeared. All three confirm this connection, but the third in addition suggests that aggressive treatment with herpes anti-viral medication can significantly reduce the chance of encountering dementia. However, the study did not attempt to deal with people who had already encountered dementia.
Here are two media articles:
Herpes linked to Alzheimer’s: Antivirals may help
Alzheimer’s risk 10 times lower with herpes medication
Here is an interesting scientific commentary by two researchers active in the area (referenced in both media articles linked above):
Herpes Viruses and Senile Dementia: First Population Evidence for a Causal Link
Here are links to the first two research studies
Increased risk of dementia following herpes zoster ophthalmicus
Epidemiology and long-term disease burden of herpes zoster and postherpetic neuralgia in Taiwan: a population-based, propensity score-matched cohort study
Here is the abstract of the third research article which provides information that “The usage of anti-herpetic medications in the treatment of HSV infections was associated with a decreased risk of dementia”:
Anti-herpetic Medications and Reduced Risk of Dementia in Patients with Herpes Simplex Virus Infections-a Nationwide, Population-Based Cohort Study in Taiwan.
