| Abstract: | Due to the demographic change and an aging society more research is nowadays dedicated to geriatric problems and questions. Aging is associated with a loss of grey matter volume in the brain and often leads to neurodegenerative diseases. Physical and cognitive activities have been shown to improve brain plasticity whereby the combination of both seems to be most effective. We hypothesized that dancing could be an ideal intervention because it combines exercise, cognitive, coordination and emotional features. In this study 26 healthy senior citizens (63–80 years old) were randomized into a dancing group (n = 14) or a physical exercise group (n = 12). After 18 months the dancing group showed increased grey matter volumes, especially in the frontal and temporal regions including the gyrus parahippocampalis and the precentral gyrus. The physical exercise group showed grey matter volume increases only in subcortical regions. Our results suggest that dancing is more effective in inducing neuroplasticity in regions normally affected by aging than classical repetitive fitness training. We assume this to be related to the multimodal nature of dancing, which combines exercise, cognitive and coordination features. These findings demonstrate for the first time in a longitudinal study the positive effects of dancing programs for the prevention of volume loss of grey matter and neurodegenerative diseases in the elderly. |
