(Associated Press) A vaccine to fight dementia? It turns out there may already be one – shots that prevent painful shingles also appear to protect aging brains.
A new study found that shingles vaccination cut older adults’ risk of developing dementia over the next seven years by 20%.
The research, published Wednesday in the journal Nature, is part of growing understanding about how many factors influence brain health as we age – and what we can do about it.
“It’s a very robust finding,” said lead researcher Dr. Pascal Geldsetzer of Stanford University. And “women seem to benefit more,” which is important as they’re at higher risk of dementia.
The study tracked people in Wales who were around 80 when receiving the world’s first-generation shingles vaccine over a decade ago. Now, Americans 50 and older are urged to get a newer vaccine that’s proven more effective against shingles than its predecessor.
