Weight-Loss Surgery Associated With Reduced Dementia

A new study reported in Annals of Surgery Open suggests that bariatric surgery, also known as weight-loss surgery, may help reduce the risk of cognitive decline and dementia in people with obesity. You Chen, PhD, Yubo Feng, MS, Sayeed Ikramuddin, MD, and colleagues analyzed medical records from over 15,900 patients at Vanderbilt University Medical Center from 2000 to 2023. Among patients who developed mild cognitive impairment, those who had undergone bariatric surgery developed it about two years later than those who did not, suggesting that the surgery may have delayed the onset.
