Motoric Cognitive Risk syndrome (MCR) as well as depression and depressive symptoms (i.e. anxiety, depressive symptomatology and/or clinical depression — ADSCD) are associated with cognitive complaint and slow gait speed. Overlap with other syndromes (such as depression and/or depressive symptoms) may influence the predictive value of MCR.

• To examine whether there was an association between ADSCD and MCR in the participants of the Canadian Longitudinal Study on Aging (CLSA)
• To determine whether the nature of depressive symptoms and age may influence this association

The design is a cross-sectional study, which used the baseline assessment of CLSA.

A total of 29,569 participants from the CLSA were included after excluding those 1) lacking walking speed data and/or 2) diagnosed with dementia or AD. Participants were categorized by age groups and MCR diagnosis. Intra-group comparisons were completed using the unpaired t-test or Chi square test. Multiple logistic regressions were also performed to examine the association between MCR and depressive symptomatology, while adjusting for multiple variables.

MCR may be a clinical manifestation of depression or depressive symptomology in younger individuals, whereas it may be related to both depression and the predementia phase in older adults.
