Acta Neurol Scand: Six months of dance movement intervention can alter the brain structure of non-dementia elderly people

The study, which aims to evaluate the effects of the six-month Dance-Exercise Enhancement Intervention (DI) on the cognitive and brain structure of healthy older adults and people with mild cognitive impairment, was published online in Acta Neurol Scand.
subjects (under 60 years of age, no dementia or depression) were randomly assigned to the DI group or the life-as-usual group.
conducted detailed neuropsychological tests, physical measurements, and brain MRIs containing T1 structure and dispersion imaging (DTI) at baseline and six months later.
the changes in cortical thickness and DTI parameters were evaluated.
results, a total of 62 people (31 in the DI group) completed the study.
the demographic and clinical variables of each group.
6 months, the cortical cortical area of the lower right armpage, spindle shape and outer pillow of the DI subjects increased significantly compared to the control group.
the radial and average dispersion of each white pathway increased significantly in the DI subjects, no differences were observed between the DI group and the LAU group.
the DI group is slightly improved in its execution function compared to the LAU group.
In summary, the study observed an improvement in DI-induced executive function and an increase in the thickness of the pillow side cortical cortical layer, which engaged in motion observation, visual motion integration and motion imitation, which were important for motion learning and performing skilled movements.
