Relation Between Intellectual Dysfunctioning and Mortality in Community‐Residing Older People

Abstract

Intellectual dysfunctioning, as measured by an assessment instrument developed by OPCS, represents an increased risk factor for mortality among community-residing older people.

Risk of mortality for dementia in a developing country: the Yoruba in Nigeria

“…After adjusting for demographics and comorbid conditions, poor and intermediate performers on the CSI-D had a similar increased risk of mortality at both sites, with poor performers tending to have an increased risk of mortality compared to the intermediate performers. The RR ranging from 1.5 to 2.0 reported in this study were comparable in magnitude with other studies (Liu et al, 1990;Kelman et al, 1994;Arfken et al, 1999;Nakanishi et al, 1998;Frisoni et al, 1999) that defined cognitive impairment with the use of screening instruments.…”

Dementia, cognitive impairment and mortality in persons aged 65 and over living in the community: a systematic review of the literature

“…Eleven studies in Table 2 present risks for a number of different levels of cognitive impairment within the same study and it is worth noting that all of these studies except Nakanishi et al (1998) show a monotonic increase in risk with increasing impairment.…”

“…Of the CI shown for the various effect sizes only nine include a relative risk of unity (two each from Liu et al (1990) and Nakanishi et al (1998) and one each from Arve et al (1998), Davidson et al (1988), Ho (1991), Saz et al (1999) and Shapiro and Tate (1991)) all of which except Arve et al (1998) represent mild levels of impairment.…”

Cognitive Impairment and Mortality in Older Primary Care Patients

“…We were unable to identify other studies in the literature reporting similar data for a large population of urban economically disadvantaged older adults. We identified only two community‐based studies focusing on non‐Caucasian populations that addressed the relationship between cognitive impairment and mortality 15,17 . A third study enrolled patients admitted to a rehabilitation hospital 12 .…”
