Abstract

INTRODUCTION: Cognitive impairment is associated with increased mortality. We examined the association between motoric cognitive risk (MCR) syndrome, a predementia syndrome characterized by slow gait and cognitive complaints, and survival.

METHODS: A total of 11,867 nondemented participants aged >65 years from three established cohort studies in the United States and Europe were screened for MCR. Mortality risk of MCR was assessed with Cox and logistic regression models.

RESULTS: At baseline, 836 (7.0%) participants had MCR. Over a median follow-up of 28 months, 1603 participants died (758 in first 2 years). MCR was associated with increased mortality overall (adjusted hazard ratio, 1.69; 95% confidence interval [CI], 1.46-1.96) and 2-year mortality (adjusted odds ratio, 1.89; 95% CI, 1.50-2.38). The association remained after accounting for established mortality risk factors as well as baseline gait speed and memory performance.

DISCUSSION: MCR is associated with increased mortality. Older adults should be screened for MCR to identify at-risk individuals for dementia and death.
