The "Motoric Cognitive Risk" Syndrome in the Canadian Population

The "Motoric Cognitive Risk" Syndrome in the Canadian Population: Analysis of Baseline Assessment of the Canadian Longitudinal Study on Aging (CLSA)

Cognition and locomotion are two human abilities controlled by the brain. Their decline is highly prevalent with aging, and is greater than the simple sum of their respective prevalence, suggesting a complex age-related interplay between cognition and locomotion. Recently, a systematic review and meta-analysis has provided evidence that poor gait performance predicts dementia and, in particular, has demonstrated that "motoric cognitive risk" (MCR) syndrome, which has been described in cognitively healthy individuals and combines subjective cognitive complaint with objective slow gait speed, is a pre-dementia syndrome. The uniqueness of "motoric cognitive risk" (MCR)syndrome is that it does not rely on a complex evaluation or laboratory investigations. Thus, it is easy to apply in population-based settings. The overall objective of the proposal is to examine the epidemiology of the newly reported "motoric cognitive risk" (MCR) syndrome, in the Quebec population using the database of the NuAge study.
