Vaccine to protect against dementia? This reduces the risk by 20%

With the increase in cases of dementia and Alzheimer’s disease, scientists are investigating new ways of limiting their influence. But a surprising breakthrough suggests that protection can be already at your fingertips. The last study suggests that the half -press of the vaccine, which protects against a painful viral rash, can also reduce the risk of dementia in the elderly.

Earlier studies have shown that there is a reduced risk of dementia among people vaccinated. However, many were biased, because vaccinated people are more aware of health, which makes it difficult to determine whether the vaccine itself offers protection or lifestyle factors such as diet and exercises.

To solve this problem, scientists from Stanford Medicine used the unusual public health policy in Wales. In 2013, the half -lane vaccination program set strict qualification principles based on age: those who were 79 years old on September 1 could receive a vaccine this year, while those who were 80 years old before the border was never authorized.

Both groups had similar levels of education, vaccination habits and indicators of conditions such as diabetes and heart disease. This created a unique opportunity to compare two almost identical groups, differing only in access to the vaccine, enabling researchers to isolate the true influence of the vaccine from lifestyle factors.

“What makes the study so powerful is that it basically resembles a randomized study with a control group – a bit too old to qualify for the vaccine – and the intervention group – those who are young enough to qualify” – said Dr. Pascal GeldSetzer, senior author of the study in A research in A press release.

The study showed that those who received semi -lane vaccine were 20% less exposed to the development of dementia over the next seven years than those who did not receive the vaccine. Scientists also noticed that protection against dementia was particularly stronger in women than in men. This is probably caused by gender differences in immune response or the difference in the development of dementia.

“For the first time we are able to say much more confidently that the Half -Fassy vaccine causes a reduction in the risk of dementia. If this is really the causal effect, we have a discovery of great meaning,” added Dr. Geldsetzer.
