Read Medical Records Links Viruses to Alzheimers. A study of 500,000 medical records links viruses to Alzheimer’s over and over again.
A study of around 500,000 medical records suggested that serious viral infections such as encephalitis and pneumonia increase the risk of neurodegenerative diseases such as Parkinson’s and Alzheimer’s. The researchers found 22 connections some different between viral infections & neurodegenerative conditions in the study of about 450,000/- people.

Tthe People treated for a type of brain inflammation called viral encephalitis. There were some 31 times more likely to develop Alzheimer’s disease. In 406 cases of viral encephalitis, 24 developed Alzheimer’s disease, about 6%.)

Those who were hospitalized with pneumonia after contracting the flu appeared to be more susceptible to Alzheimer’s disease, dementia, Parkinson’s disease and amyotrophic lateral sclerosis (ALS).
Intestinal infections and meningitis (both often caused by viruses), as well as the varicella-zoster virus, which causes shingles, have also been implicated in the development of several neurodegenerative diseases.
Massive Health-Record Review Links Viral Illnesses to the Brain
The impact of viral infections on the brain persisted for up to 15th years in some cases. And there were no cases in which virus exposure was protective.
About 80 percent of the viruses implicated in brain diseases were considered “neurotrophic,” meaning they could cross the blood-brain barrier.
Surprisingly, there are currently vaccines available for some of these viruses, including influenza, herpes zoster varicella zoster, & pneumonia, the researchers write.
“Although vaccines do not prevent all cases of disease, they are known to dramatically reduce hospitalization rates. This evidence is suggests that vaccination may mitigate some important new risk of developing neurodegenerative some different diseases.”

Last year, a study of more than 10 million people linked the Epstein-Barr virus to a 32-fold increased risk of multiple sclerosis.
- First, the researchers analyzed the medical records of around 35,000 Finns with six different types of neurodegenerative diseases and compared them with a group of 310,000 controls who did not have a brain disease.
- This analysis yielded 45 links between viral exposure & neurodegenerative diseases & this was narrowed down to 22 more links in a subsequent analysis of 100,000/- UK Biobank medical records.
“Neurodegenerative disorders are a collection of diseases for which there are very few difficulty effective treatments & many risk factors,” said co-author Andrew Singleton, a neurogeneticist & Alzheimer’s disease researcher & director of the Center for Alzheimer’s Disease & Related Dementias. .
