Dementia risk reduced with flu vaccine

0
Researchers from Taipei Medical University (New Taipei City, Taiwan) have suggested that influenza vaccination may lower the risk of dementia in heart failure patients. Following the large-scale study of more than 20,000 patients, the researchers propose that the vaccination reduces dementia risk by preventing inflammation that may be induced by flu.

“Previous studies have shown that there is link between impairment in cognitive function and heart failure,” explained Ju-Chi Liu, Taipei Medical University. “Some reports have also suggested that inflammation after getting the flu might contribute to dementia. However, there are no solid data to demonstrate that influenza vaccination could decrease the relative risk of dementia in patients with heart failure.”

The new large-scale study, presented at Heart Failure 2016 and the 3rd World Congress on Acute Heart Failure (Florence, Italy, 21–24 May 2016), addressed whether the vaccination reduces dementia risk specifically in heart failure patients in Taiwan. Participants comprised 20,000 patients over 60 years of age who had been diagnosed with heart failure in 2000 to 2012.
