A 3-month aerobic dance program improved cognitive function and strengthened structural connections within the default mode network in older adults with amnestic mild cognitive impairment. Sixteen participants in the exercise group showed significant gains in global cognition, memory, and executive function compared to baseline, while the control group showed no change. The exercise group also had increased structural connections between the hippocampus and several temporal regions, as well as between the default mode network and the supplementary motor area. These connectivity changes correlated with better cognitive scores, suggesting that aerobic dance may enhance brain structure and memory in this population.
