Shingles Vaccine Linked to Reduced Dementia Risk

A new study has found that shingles vaccination may not only protect against painful skin lesions but also reduce the risk of developing dementia. Researchers analyzed data from over 280,000 medical records in Wales and discovered that seniors who received the first-generation shingles vaccine showed a 20% decrease in dementia risk over the next seven years.

The study’s lead researcher, Dr. Pascal Geldsetzer, noted that women seemed to benefit more from the vaccination. The findings add another reason for people to consider getting vaccinated against shingles, particularly as it has been linked to an increased risk of dementia.

Shingles is a common condition affecting nearly everyone born before 1980, caused by the same virus that causes chickenpox. While most recover, some experience severe complications, including nerve pain and vision loss. The Centers for Disease Control and Prevention estimate that up to 20% of shingles patients suffer from excruciating nerve pain.

The link between shingles and dementia is not fully understood, but research suggests that certain viruses, including those in the herpes family, may contribute to its development. Shingles has been shown to cause inflammation, which can lead to cognitive decline, and directly infect blood vessels in the brain, increasing the risk of strokes and dementia.

While the exact mechanism is unclear, studies have found that shingles vaccination may offer some protection against dementia. The new findings add weight to the recommendation to get vaccinated against shingles, particularly for seniors. However, it’s essential to note that other brain-healthy habits, such as exercise and a balanced diet, also play a crucial role in reducing dementia risk.

As the study highlights, more research is needed to fully understand the relationship between shingles vaccination and dementia risk. The CDC recommends that adults aged 50 and older receive the Shingrix vaccine, which has been shown to be more effective against shingles than its predecessor, Zostavax.
