Topic: Risk, prevention and care in population studies
Background To establish trajectories of cognitive and motor function, and to determine the sequence of change across individual tests in community-dwelling individuals aged 45-90 years. Method Between 1997 and 2016, we repeatedly assessed cognitive function with 5 tests in 9514 participants aged 45-90 years from the population-based Rotterdam Study. Between 1999 and 2016, we measured motor function with 3 tests in 8297 participants.

Key findings
- Method Between 1997 and 2016, we repeatedly assessed cognitive function with 5 tests in 9514 participants aged 45-90 years from the population-based Rotterdam Study.
- Between 1999 and 2016, we measured motor function with 3 tests in 8297 participants.
- All participants were free from dementia, stroke, and parkinsonism.
- We assessed overall and education-specific cognitive and motor trajectories using linear mixed models with age as time scale.
Why it matters
This population-based study described how cognitive and motor function change with age in people aged 45 to 90 who were free of dementia, stroke, and parkinsonism. It charts normal aging trajectories and does not test any treatment, cure, or prevention.
