Key Points

To assess the relationship between prior metabolic and bariatric surgery (MBS) and the likelihood of cognitive impairment in adults.
Analyzed 4,597,465 hospitalizations with obesity from the 2016-2022 Nationwide Inpatient Sample.
Applied doubly robust risk adjustment using entropy balancing and multivariable regression models.
Focused on cognitive impairment subclasses, including Alzheimer's disease, vascular dementia, and Wernicke's Encephalopathy.
Prior MBS was associated with lower odds of Alzheimer's disease (AOR 0.67, 95% CI 0.59-0.75).
Prior MBS linked to lower odds of vascular dementia (AOR 0.55, 95% CI 0.47-0.64).
Higher odds of Wernicke's Encephalopathy were observed post-MBS (AOR 5.03, 95% CI 3.76-6.72).
