Do viruses play a role in Alzheimer’s disease?

A new study, analyzing a large set of data from post-mortem brain samples of individuals with and without Alzheimer’s disease, has demonstrated the potential role of viruses in Alzheimer’s disease biology.

The research neither proves the role of viruses in the onset or progression of Alzheimer’s, however; the findings do demonstrate that viral DNA sequences and the biological networks they activate can interact with genetic, molecular and clinical properties of Alzheimer’s.

“The hypothesis that viruses play a part in brain disease is not new, but this is the first study to provide strong evidence based on unbiased approaches and large data sets that lends support to this line of inquiry,” explained NIA Director Richard J Hodes. “This research reinforces the complexity of Alzheimer’s disease, creates opportunities to explore Alzheimer’s more thoroughly and highlights the importance of sharing data freely and widely with the research community.”
