Differential dementia risks of motoric cognitive risk syndrome and mild cognitive impairment among older adults in China: a 7-year cohort study

Both MCI and MCR were associated with an increased risk of dementia, and the co-occurrence of MCI and MCR conferred a higher risk of dementia. Although the MCR group showed no significant baseline cognitive impairment, their subsequent cognitive decline and dementia risk were higher than those of the MCI group. Therefore, promoting MCR screening in China's primary healthcare system may be more feasible than MCI screening, which could help in early identification of high-risk populations and the implementation of targeted interventions to delay or prevent the onset of dementia.
