LAY SUMMARY
This study, by Dr. Montero-Odasso and CCNA colleagues, describes how cognitive and motor trajectories fluctuate in older adults before progressing to dementia. Importantly, this is the first study to provide empirical evidence of the added value of combining objective motor and cognitive declines to detect incident dementia, especially when compared to either motor or cognitive decline alone. Moreover, the results show how a single time-point assessment failed to detect individuals at high risk of dementia, emphasizing the importance of routine assessment of motor performance in older adults with cognitive impairments.
