People Who Have Severe Obesity May Show Evidence Of Impaired Cognition Even When They Have No Signs Of Prediabetes Or Diabetes, Research Suggests

reported, “Severely obese people show evidence of impaired cognition even when they have no signs of prediabetes or diabetes, but retinopathy and nephropathy only occur in those with hyperglycemia,” researchers concluded in a study that found that “the prevalence of cognitive deficit was 6.5% in lean controls, 22.2% in normoglycemic obese participants, 17.7% in obese participants with prediabetes, and 25.6% in obese participants with diabetes, based on a National Institutes of Health...Toolbox cognitive composite score below the fifth percentile for lean controls.” Included in the study were “138 severely obese individuals (BMI >40 kg/m2 or BMI >35 kg/m2 with at least one comorbid medical condition) who were due to undergo bariatric surgery and 46 lean controls.” The findings were published online in Diabetes Care. https://www.medwirenews.com/diabetes/severe-obesity-may-be-associated-with-impaired-cognition/17591008
