In an astonishing revelation, new research has unveiled that the vaccine designed to combat shingles may also help lower the risk of dementia. This breakthrough study, published in the prestigious journal *Nature*, highlights that older adults who receive the shingles vaccine can see a 20% reduction in their risk of developing dementia over the following seven years.

Lead researcher, Dr. Pascal Geldsetzer from Stanford University, stated, “It’s a very robust finding,” underscoring the significance of this discovery. Notably, the study suggests that women appear to benefit even more from the vaccine, a crucial point given their higher susceptibility to dementia.

This extensive research tracked individuals in Wales who were around 80 years old at the time they received the world’s first-generation shingles vaccine over a decade ago. The implications are particularly relevant now, as health experts recommend that Americans aged 50 and older receive the updated Shingrix vaccine, known for its enhanced protection against shingles.

Dr. Maria Nagel from the University of Colorado Anschutz Medical Campus elaborated that the varicella-zoster virus, which causes shingles, is a known risk factor for dementia, and the availability of a vaccine that helps mitigate this risk is a significant development.

With the incidence of Alzheimer’s and other forms of dementia on the rise in an increasingly aging population, Dr. Anupam Jena, a noted physician and health economist at Harvard, highlighted in a commentary that “the implications of the study are profound.”

For many, the connection between chickenpox and shingles may seem distant, but nearly everyone born before 1980 carries the chickenpox virus. This virus remains dormant in the nervous system and can resurface as shingles, particularly when the immune system weakens due to age or illness. Shingles is not only painful but can lead to severe complications, including vision loss if it affects the eyes, and prolonged nerve pain even after the rash has healed.

While the precise causes of Alzheimer’s and other dementias are not fully understood, certain viruses, particularly those in the herpes family—like the chickenpox virus—are believed to contribute to the development of these conditions.

Interestingly, previous studies have suggested that a shingles outbreak may increase the risk of dementia by around 20%. This is, in part, due to the inflammation caused by the virus, which can adversely affect organs, including the brain. Moreover, inflammation can lead to blood vessel infection in the brain, heightening the risks of strokes and cognitive decline.

In a fascinating twist, Dr. Nagel’s laboratory discovered that shingles could catalyze the formation of amyloid, a sticky protein associated with Alzheimer’s disease.

Previous findings confirmed a correlation between those who receive vaccines and other brain-healthy habits, such as regular exercise and a balanced diet, complicating the task of definitively establishing an additional benefit from vaccination.

Capitalizing on what is termed a “natural experiment” in Wales, researchers compared those just young enough to qualify for the vaccine with those who just missed out, effectively mimicking a controlled study. An analysis of over 280,000 medical records yielded evidence that vaccinations did indeed provide protective benefits against dementia, with participants receiving a vaccine called Zostavax during the study.

The next phase of research will investigate whether the current Shingrix vaccine also offers similar protective effects against dementia. Interestingly, recent discussions have emerged about its potential benefits. Collaborations between vaccine manufacturers and health officials aim to monitor the cognitive health of seniors post-vaccination.

Shingrix is administered in two doses over several months and is recommended by the CDC starting at age 50, as well as for younger individuals with specific immune-weakening conditions. Alarmingly, less than 40% of eligible Americans have opted for vaccination.

While side effects like injection site pain and mild flu-like symptoms are common, experts advise those currently battling other viruses, such as the flu or COVID-19, to postpone receiving the shingles shot until recovery.

Although no surefire method exists to prevent dementia, doctors continue to advocate for several commonsense strategies, including maintaining social and cognitive engagement and managing health conditions like high blood pressure and diabetes, both of which are linked to cognitive decline.
