Vantieghem S, et al. - Researchers examined the effect of a 30-week lasting weight loss program on cognition and how the changes in body composition and self-perceived fatigue effected cognition changes. For this investigation, 62 obese adolescents were assessed at baseline and after 30 weeks. They evaluated Stroop test (selective attention), Continuous Performance Test (sustained attention) and Ray Auditory verbal learning test (short-term memory). The data showed a 30-week lasting inpatient weight loss program improved selective attention, sustained attention, and short-term memory. The improvements in cognitive functioning were not explained by changes in body composition. It was noted that decreased fatigue resulted in improved parts of cognition.
