Herpes medication plays vital role in Alzheimer’s treatment, new results show. The herpes simplex virus is involved in the condition and antiherpetic medication has a considerable effect on dementia risk.
Last month’s report based on a study discovered a “strong evidence” of an association between the viruses and Alzheimer’s disease.
People suffering from the condition had more herpesviruses 6 and 7 than people free from Alzheimer’s, according to the postmortem analyses of brain tissue.
Now a new a new study – combination of three studies – published in the Journal of Alzheimer’s Disease have strengthened the link between herpes and dementia.
Two of the studies note that acute herpes zoster infection causes dementia risk and another one shows that antiherpetic medication minimizes the dementia risk.
The latter study analyzed 8,362 people aged 50 and above diagnosed with herpes simplex virus (HSV) infection and 25,086 age-matched healthy people.
The researchers followed both groups for almost ten years, between 2001 and 2010. They found that the risk of dementia was over 2.5 times higher in the herpes group than in the group of healthy people. The study concluded that antiviral treatment lowered the dementia risk by 10 times that means herpes medication plays vital role in Alzheimer’s treatment.
This article and two others provide the first population evidence for a causal link between herpes virus infection and Alzheimer’s disease, a hugely important finding,” said Prof. Itzhaki, researcher and who is a professor of neuroscience and experimental psychology at the University of Manchester in the United Kingdom.
“I believe we are the first to realize the implications of these striking data on this devastating condition which principally affects the elderly,” Itzhaki adds.
