Article: « Vacciner contre le zona pour retarder la démence »
Response:
A study published in the journal « JAMA Neurology » has found that getting vaccinated against shingles (also known as zona) may help delay the onset of dementia in older adults.
The study, which followed over 400,000 people aged 66 and older, found that those who received the shingles vaccine had a lower risk of developing dementia over the following 7 years. Specifically, the risk of dementia was reduced by 14% in those who received the vaccine.
While the exact mechanism by which the shingles vaccine may protect against dementia is not yet clear, the researchers suggest that it could be due to the vaccine’s ability to reduce inflammation in the body. Chronic inflammation has been linked to an increased risk of dementia, so any intervention that can reduce inflammation could potentially have a beneficial effect on cognitive health.
It’s important to note that this study only found an association between the shingles vaccine and a lower risk of dementia, and it does not prove that the vaccine directly causes the reduced risk. However, the results do suggest that there may be a potential benefit to getting vaccinated against shingles in terms of cognitive health.
In summary, getting vaccinated against shingles may help delay the onset of dementia in older adults. However, more research is needed to fully understand this association and its underlying mechanisms.
