Three Vaccines Reduce Risk of Alzheimer’s Disease in Adults Over 65, Study Shows

he Alzheimer’s disease It is a form of dementia that, together with other such neurodegenerative diseases, affects about 900,000 people in Spain. These age-related conditions are among the leading causes of death, disability and dependence. There are two essential proteins in Alzheimer’s disease: beta-amyloid and phosphorylated tau. Today, excess amyloid is known to be the cause of the disease, and after this protein appears, the Tau protein changes.

There are several theories about the cause of Alzheimer’s disease. (EA). One hypothesis is that infections may play a role in the development of AD and disease-related dementias, as they may increase neuroinflammation, which causes or exacerbates neurodegeneration that leads to dementia.

Vaccines can reduce the risk of infection or limit its severity Reduce neuroinflammatory burden in individuals. A recent study by the UTHealth Houston Center for Scientific Research and Academics suggests that certain vaccines can reduce the risk of Alzheimer’s disease in adults over age’s about Tetanus and diphtheria vaccine with or without pertussis (Tdap/Td) Herpes zoster (HZ)better known as herpes zoster; and pneumococcus.

A little over a year ago, a team led by Paul E. Schulz, a professor of neurology at McGovern Medical School in Houston and the study’s lead author, published another study detailing patients who had received at least one healer 40% less likely to get a flu shot more likely than their unvaccinated peers to develop Alzheimer’s disease.

In the new study, they found that vaccinated people insecticide Tetanus, diphtheria, and pertussis, and patients treated with Td for the first of these two diseases 30% less likely More likely than their unvaccinated peers to develop Alzheimer’s disease (7.2% of vaccinated patients compared with 10.2% of vaccinated patients).

along with 25% reduction in shingles vaccine risk of Alzheimer’s disease, which the pneumococcal vaccine reduced by 27% (7.92% in vaccinated patients vs 10.9% in unvaccinated patients)

We wondered if this finding was specific to flu vaccines.These data suggest that several other vaccines For adults, also reduces risk of Alzheimer’s diseaseSchultz said. “We and others have hypothesized that the immune system is responsible for the dysfunction of brain cells in Alzheimer’s disease. The findings show us that vaccination has a more general effect on the immune system that reduces the risk of Alzheimer’s disease. “

For this study, The research team analyzed a group of patients aged 65 or older without dementia for two years, with eight years of follow-up. To do this, they compared vaccinated and unvaccinated people and overlaid comparisons between people with Alzheimer’s disease and unvaccinated people.
