According to Alzheimer’s disease International (ADI 2016), as a result of the demographic aging, by 2030 there will be 65.7 million people suffering from dementia worldwide and by 2050 there will be 115.4 million. In this sense, cognitive decline has emerged as one of the most common agerelated health problems for older adults and is associated with increased risk for progression to dementia, increased physical disabilities, and also increased health care costs.
Cognitive impairment underlines
The high prevalence of cognitive impairment underlines the need for effective interventions to improve cognition in older adults. Fratiglioni et al. propose three lifestyle factors play a significant role in slowing the rate of cognitive decline and preventing dementia: social network, cognitive leisure activity, and regular physical activity. Dance, as a novel multicomponent interventional approach, sparke increasing interest of gerontology researchers.
A number of randomize control trials have shown that dance can support physical function; which improve cognitive performance, reduce the amount of depressive symptoms, and promote life satisfaction in older adults. Dance is not only an ideal physical activity but also an engaging social activity; hence that improves fitness levels and promotes healthy activity, which are important for successful aging.
Dance can be perform in relax and pleasant environments; hence has a great natural appeal to older adults compare to other conventional exercises. Many studies identify dance as a motivator for the older adults to adhere to a physical activity program. This is the first meta-analysis and systematic review to evaluate the efficacy of dance intervention on global cognition, executive function and memory in older adults.
Positive effect of dance
The present meta-analysis show a positive effect of dance on global cognition, while there were no significant differences of dance on executive function in elderly. The present quantitative analysis show that dance may benefit memory function in older adults. However, in there review, dance was more effective for elderly cognitions than exercise may be not support. Seven studies evaluate the effect of dance intervention on global cognition in older adults.
The effects of dance on executive function in older adults Aging Clinical; also Experimental Research no-exercising controls. In these individual studies, five out of seven report significant improvement for dance groups. Meta-analysis results reveal that dance significantly improve global cognition in elderly. Four studies that compare with non-exercising controls; hence were conduct to evaluate the effectiveness of dance intervention on memory.
Exercise affects cognition by increasing brain-derived neurotrophic factor (BDNF) and synapses, and promoting neuronal growth and survival. There meta-analysis and systematic review suggest that dance may be a safe and effective approach to improve cognitive function in older adults. However, studies with larger, high quality, and homogeneous are required to determine the effects of dance on executive function and memory function.
