As dementia and Alzheimer's cases continue to rise, researchers are exploring new ways to curb their impact. But a surprising breakthrough suggests that protection might already be within reach. A recent study suggests that shingles vaccine, which protects against the painful viral rash, may also reduce the risk of dementia in older adults.
Earlier studies have shown that there is reduced dementia risk among those vaccinated with shingles. However, many were biased, as vaccinated individuals tend to be more health-conscious, making it difficult to determine whether the vaccine itself offered protection or if lifestyle factors like diet and exercise played a role.
