The Cognitive-Prefrail Syndrome and Its Association With Adverse Health Outcomes

Plain-language summary

Lay Summary Older adults who are prefrail (an intermediate, potentially reversible stage between robustness and frailty) with early symptoms of cognitive impairment are a segment of the population that have hitherto remained "silent" and are currently not targets for screening and intervention. These individuals require early identification for preventive interventions to reduce disability, dependency and improve quality of life. To date, there is still no accepted definition of individuals upstream in the spectrum of physical frailty and cognitive impairment. Determining the prevalence and predictive ability of various definitions of co-existent frailty and cognitive impairment could identify older adults at greatest risk of adverse health outcomes. Therefore, the researchers aim to examine and compare (1) the prevalence of cognitive-prefrailty, prefrailty (IANA/IAGG consensus definition) and MCR syndromes, (2) the incidence and predictive ability of these three syndromes for adverse health outcomes including cognitive impairment and decline, dementia, physical functional impairment and decline, falls, hospitalization and mortality in older Quebec community dwellers.
