Abstract

Background and Objectives: The motoric cognitive risk syndrome (MCR) is a predementia syndrome characterized by slow gait and cognitive complaint. The relationship between MCR and social support-a potentially modifiable risk factor of dementia-is currently unknown. The current study aimed to determine whether MCR incidence varies as a function of social support in aging. Research Design and Methods: We examined MCR incidence in 506 community-dwelling older adults (M Age 76.59; 57.3% female) without MCR or dementia at baseline. We quantified perceived levels of social support with the Medical Outcomes Study Social Support Survey, incorporating four different categories of support: (a) emotional/informational support, (b) tangible support, (c) affectionate support, and (d) positive social interactions. We used Cox regression analyses, adjusted for age, sex, race/ethnicity, education, marital status, comorbidities, and global cognition, to estimate hazard ratios (aHR) with 95% confidence intervals (CIs). Results: Over a median follow-up time of 2.5 years (range=1-7 years), 38 participants (9.8%) developed MCR. Increased tangible support decreased the risk of MCR by 30% (aHR: 0.70, 95% CI: 0.53-0.92, p=.011). Increased overall social support decreased the risk of MCR by 33% (aHR: 0.67, 95% CI: 0.46-0.98, p=.038). Other subcategories of social support were not associated with a decreased risk of MCR (p>.05). Discussion and Implications: Higher levels of tangible social support, as well as overall social support, were associated with reduced risk for MCR in older adults. Increasing social support may be a promising avenue of intervention for reducing the risk of MCR, dementia, and other forms of cognitive decline.
