Study reveals that bariatric surgery can help stabilize cognition in the long term
A study conducted by the University of Michigan, US, found that an obese person who underwent bariatric surgery had a stable cognitive level after two years, indicating positive results in arresting the decline. Commenting is the digestive system surgeon Dr. Rodrigo Barbosa, from the capital Sao Paulo.
“Obesity can cause cognitive decline, since, among the associated comorbidities, diabetes is also associated with worsening cognitive abilities. But the good news is that the study showed that the cognitive score was better in patients who underwent surgery bariatric,” says the doctor.
In this study, 87 participants with an average age of 46.8 years were analyzed, of which 73.6% were women and 77% were white. All class II obese (with body mass index from 35 to less than 40) or class III (BMI equal to or greater than 40) of which 27.6% also had diabetes and 28.8% were taking medications to reduce blood sugar levels. Of these, 77 underwent gastric sleeve surgery and the other 10 underwent gastric bypass. Preliminary measurements were taken before the study to measure weight, height, body mass index (BMI), blood pressure, fasting lipid level, and HbA1c (blood sugar measurement). The patients’ IQ and emotions were also measured. Cognitively, the study used a standardization known as the National Institutes of Health (NIH) Toolbox Cognition Battery (NIHTB-CB), which measures attention, executive function, episodic memory, working memory and the processing speed. Two years after the study began, one participant showed a change in cognitive score. She initially had a score of 106. Two years after bariatric surgery, she had a score of 106.7.

Dr. Rodrigo explains that while more in-depth studies on the topic are still needed, other research conducted by the Longitudinal Assessment of Bariatric Surgery (LABS) also showed that bariatric surgery can improve memory after evaluating bypass patients gastric, while that of mixed procedures at the University of Michigan. “The difference between the surgeries may have to do with the different outcomes, but we can already say that the slowing of cognitive decline may indicate that the bariatric procedure is related to this, in addition to many other benefits of losing weight after surgeries procedures,” he says. .
