A new study found
shingles vaccination cut older adults' risk of
developing dementia over the next seven years by 20 per cent.
The research, published 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 in the US state of California. And 'women seem to benefit more', important as they are 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 has proven more effective against shingles than its predecessor.

The new findings add another reason for people to consider rolling up their sleeves, said Dr Maria Nagel of the University of Colorado Anschutz Medical Campus, who studies viruses that infiltrate the
nervous system
