Scientists develop blood test for Alzheimer’s disease

Researchers are beginning to better understand the damage that a lifetime of viral infections can do to the brain, calling attention to the importance of vaccines, which could play a significant role in minimizing the number of viral infections occurring. If viral infections increase individuals' risk of developing neurological diseases, then vaccines and antivirals should be explored as a means of reducing this risk.
While these types of studies are undoubtedly significant, we need to be cautious not to confuse correlation with causation. This analysis merely shows a relationship between viral infections and brain disease, but falls short of proving that a virus leads to neurodegenerative disease. More robust studies are needed to add weight to such a claim and offer tangible ways to delay or prevent neurological disorders.
