Abstract
The present review examined the evidence for a potentially bidirectional association between mobility function and cognitive function in midlife and older adulthood. In 2023-2024, we conducted a scoping review by carrying out systematic searches on Google Scholar, PubMed, and PsycINFO for articles that included measures of mobility function and cognitive function. Of the 1,504 articles screened, 40 were included for review. The majority of reviewed studies found evidence of a relation between lower mobility function/greater mobility decline and lower cognitive function/greater cognitive decline. Prospective effects were observed in both directions; however, only five studies directly tested the bidirectionality of the association between mobility function and cognitive function. Individuals with lower mobility function may be more likely to experience declines in cognitive function and vice versa. More research is needed to further test the bidirectionality of this association and to identify protective factors that may disrupt this relation and reduce the incidence of co-occurring mobility impairment and cognitive impairment.
