Shingles Shot May Offer Dementia Shield
11 Oct
Summary
- Shingles vaccine shows potential dementia risk reduction.
- Studies suggest up to 20% lower risk, strongest in women.
- Increased demand for shingles vaccine driven by dementia fears.
A potential link between the shingles vaccine and reduced dementia risk is driving increased demand for the jab. Studies suggest that vaccination could lower the risk of dementia by up to 20%, with a more pronounced effect observed in women.
While the vaccine's primary approved use is to prevent shingles, the varicella zoster virus (VZV), which causes the condition, has been suspected of contributing to dementia by triggering inflammation and protein buildup in the brain. This has led researchers to investigate whether stimulating an immune response against VZV could offer protection.
Newer vaccines, like Shingrix, contain an adjuvant that may play a role in this protective effect. Clinical trials are ongoing to confirm these findings, but some experts suggest it may be worthwhile for individuals over 50 to consider the shingles vaccine for its potential cognitive benefits alongside its shingles prevention. However, health organizations recommend established brain health practices like exercise and a good diet as primary preventive measures.
