In a large study cohort, poor performance on several independent gait domains preceded cognitive decline and incident dementia. Researchers summarized 30 gait parameters into 7 mutually independent gait domains and a Global Gait score. Participants underwent follow-up cognitive assessments between 2014 – 2016 and were followed up for incident dementia for 4 years. Among the findings:
- 4,258 dementia-free participants (median age 67 years, 55% women) from the Rotterdam Study were included.
- 3 independent gait domains (base of support, pace, and rhythm) and Global Gait were associated with cognitive decline.
- 2 independent gait domains (pace and variability) and Global Gait were associated with incident dementia.
- Associations of gait with cognitive decline and incident dementia were only present in individuals who had been cognitively unimpaired at baseline.
