title: Effect of dance exercise on cognitive function in elderly patients with metabolic syndrome: a pilot study.
abstract: Metabolic syndrome is associated with an increased risk of cognitive impairment. The purpose of this prospective pilot study was to examine the effects of dance exercise on cognitive function in elderly patients with metabolic syndrome. The participants included 38 elderly metabolic syndrome patients with normal cognitive function (26 exercise group and 12 control group). The exercise group performed dance exercise twice a week for 6 months. Cognitive function was assessed in all participants using the Korean version of the Consortium to Establish a Registry for Alzheimer's disease (CERAD-K). Repeated-measures ANCOVA was used to assess the effect of dance exercise on cognitive function and cardiometabolic risk factors. Compared with the control group, the exercise group significantly improved in verbal fluency (p = 0.048), word list delayed recall (p = 0.038), word list recognition (p = 0.007), and total CERAD-K score (p = 0.037). However, no significance difference was found in body mass index, blood pressure, waist circumference, fasting plasma glucose, triglyceride, and HDL cholesterol between groups over the 6-month period. In the present study, six months of dance exercise improved cognitive function in older adults with metabolic syndrome. Thus, dance exercise may reduce the risk for cognitive disorders in elderly people with metabolic syndrome. Key pointsMetabolic syndrome (MS) is associated with an increased risk of cognitive impairment.Aerobic exercise improves cognitive function in elderly people and contributes to the prevention of degenerative neurological disease and brain damage. Dance sport is a form of aerobic exercise that has the additional benefits of stimulating the emotions, promoting social interaction, and exposing subjects to acoustic stimulation and music.In the present study, dance exercise for a 6-month period improved cognitive function in older adults with MS. In particular, positive effects were observed in verbal fluency, word list delayed recall, word list recognition, and the total CERAD-K score.Our data suggest that the implementation of dance exercise programs may be an effective means of prevention and treatment of cognitive disorders.
