The present study seeks to correlate cognitive functions to BMI. Participants and methods An observational study included 60 patients who underwent laboratory and clinical evaluation including BMI and a series of psychometric tests, a standardized mini-mental state examination, the Wechsler adult intelligence scale, and the Wisconsin card sorting test. Results BMI has stronger significant inverse correlation to performance intelligence quotient than the significant inverse correlation to verbal and total intelligence quotient. Also, BMI has significant inverse correlation to executive functions. Discussion Our results indicate that higher BMI is correlated to lower cognitive and executive functions. Patients with obesity had low scores on general intelligence and executive functions, particularly abstraction ability and the ability to shift cognitive strategies in response to a changing environment. Future research should incorporate brain imaging techniques to further elucidate the effects of obesity on cognition. ER -
