The neuropsychological results showed a significant decrease on Recall (p < .01), Learning (p < .10), Nonverbal Memory (p < .001), Cognitive Flexibility (p < .01) and Resistance to Interference (p < .05).ConclusionDespite the limitations inherent to a small sample, the results obtained in the Portuguese population coincide with those of earlier studies; namely that obesity differentially effects instrumental functions
