Could the Shingles Vaccine Help Protect Your Brain?

Most of us remember chickenpox from childhood. What many people don’t realize is that the virus behind it, called varicella-zoster, never really leaves your body. It simply goes quiet, hiding in your nerve cells. Later in life, especially as your immune system weakens with age, it can wake up again and cause shingles, a painful rash that can be pretty miserable.

But here’s something interesting: recent studies suggest that getting the shingles vaccine might do more than just prevent a rash. It could also lower your risk of developing dementia.

What the Studies Are Saying

In the past few years, researchers in the United States, Wales, Australia, and other countries have found that older adults who got the shingles vaccine were about 20 percent less likely to be diagnosed with dementia. That is a pretty big deal.

We don’t know exactly why this happens, but one theory is that when the virus reactivates, it may cause inflammation in the brain. That inflammation could damage brain cells and make other dementia-related problems worse. By stopping the virus from reactivating, the vaccine might help protect the brain.

What This Means for You

Before you rush out to get the vaccine just for brain health, it is important to know that we do not have proof yet. These studies show a connection, but not cause and effect. Clinical trials are underway to find out more.

That said, the shingles vaccine is already recommended for adults over 50 to prevent shingles and its complications. It is safe, effective, and has a low risk of side effects. And if it turns out to help protect your brain too, that is a great bonus.

Other Ways to Lower Dementia Risk

Right now, there is no magic pill to prevent dementia. But there are things you can do that really make a difference. Research has identified 14 lifestyle-related risk factors that are linked to dementia. These include:

• Hearing or vision loss
• High blood pressure
• Diabetes
• Obesity
• Depression
• Social isolation
• Lack of physical activity
• Drinking too much alcohol

Taking care of these areas by staying active, staying connected, and managing your health can go a long way in protecting your brain.
