Motoric cognitive risk syndrome (MCR), which is the juncture of subjective cognitive complaint and slow gait speed, is a pre-dementia stage. The aims of the study are (i) to compare characteristics between individuals who have MCR defined using slow walking speed and/or increased five-times-sit-to-stand (FTSS) time as its motor component(s); and (ii) to characterize the association of MCR and its various motor components with incident dementia including Alzheimer disease and non-Alzheimer dementia in the participants of the Epidémiologie de l'Ostéoporose (EPIDOS) study.
