Common vaccine linked to lower dementia risk in older adults
A recent study led by researchers at Brown University suggests a stronger connection between the shingles vaccination and reduced dementia diagnoses in older adults.
Study Details
Published in The Annals of Internal Medicine, the research analyzed electronic health records and Medicare claims for over 509,926 U.S. citizens aged 66 and above admitted to skilled nursing facilities.
The findings indicated that individuals who received at least one dose of Shingrix, the recombinant shingles vaccine, experienced a 24% relative decrease in dementia risk over a four-year period compared to those who did not get vaccinated.
However, the study merely reveals an association; it doesn't prove the vaccine directly prevents dementia.
Expert Opinion
Dr. Ajeet Sodhi, a clinical neurologist from Orlando, Florida, remarks that while the result is "remarkable," it aligns with growing scientific evidence rather than standing alone.
