Herpes may account for 50% of Alzheimer’s cases, leading scientist saysOctober 24th, 2018
According to new research, the Herpes virus is linked to half of all Alzheimer’s cases; the new paper was published in the Frontiers in Aging Neuroscience journal. Ruth Itzhaki, the leading professor of resent studies in Taiwan found that antiviral drugs significantly reduced the risk of dementia in patients with severe Herpes infections.
Herpes simplex (HSV1) is a common virus and the majority of the population will have contracted it by the time they reach old age and it could be behind more than half of Alzheimer’s cases. The Herpes virus remains permanently in the body and resurfaces in blisters when we are run down by stress or illness.
It’s estimated that 46 million people worldwide suffer with Alzheimer’s disease, the most common form of Dementia. Professor Itzhaki’s research suggests a potential way to treat the disease. She has found strong evidence that the Herpes virus is a cause of Alzheimer’s and suggests that effective antiviral drugs may be able to treat the disease. It could even be possible in the future to vaccinate children against it.
Previous studies presented that cold sores occur more frequently in those carrying a gene mutation called APOE -ε4 that increases the risk of Alzheimer’s.
Professor Itzhaki said: “Our theory is that in APOE -ε4 carries, reactivation is more frequent or more harmful in HSV1- infected brain cells, which as a result accumulate damage that culminates in development of Alzheimer’s”.
Researchers in Taiwan have collected population data and tested whether antiviral treatments reduce the risk of dementia.
Prof Itzhaki stated: “The striking results include evidence that the risk of senile dementia is much greater in those who are infected with HSV, and that anti-herpes antiviral treatment causes a dramatic decrease in number of those subjects severely affected by HSV1 who later develop dementia.”
Her own scientists have found HSV1 causes protein deposits characteristic of Alzheimer’s – ‘plaques’ between neurons and ‘tangles’ inside them.
She said: “Viral DNA is located very specifically within plaques in postmortem brain tissue from Alzheimer’s sufferers.
“The main proteins of both plaques and tangles accumulate also in HSV1-infected cell cultures – and antiviral drugs can prevent this.”
