Frailty and cognitive decline: how do they relate

PURPOSE OF REVIEW: To provide a comprehensive review of the recent literature (published over the last 12 months) exploring the relationship between frailty and cognition. RECENT FINDINGS: Fourteen studies were retained for the present review. No randomized controlled trial was found. Overall, the main findings of the selected studies appeared to be mainly confirmatory of the previous evidence. In longitudinal studies, physical frailty was found to predict the incidence of cognitive impairment and dementia. Cross-sectional studies showed that frail individuals have lower cognitive performance compared with nonfrail persons. Interestingly, few studies examined the association between frailty and specific cognitive functions and domains, reporting a significant impairment of attention and executive functions Finally, we found several studies including cognitive measures in the operational definitions of frailty. SUMMARY: The present findings are suggestive of an almost complete lack o
