Cambridge Cognitive Examination: performance of healthy elderly Brazilians with low education levels

Abstract

This study aimed to estimate the quartile distribution on the cognitive assessment of normal elderly with low education as measured by the Cambridge Cognitive Examination (CAMCOG). A sample of 292 elderly (> 65 years of age), screened for dementia and depression, were assessed using the CAMCOG. The CAMCOG scores of normal subjects (n = 206) were stratified according to age (65-69, 70-74, 75-79, > 80) and schooling (illiterate, 1-4, and > 5 years of formal education). Mean age was 72.8 (+/- 3.5) and mean schooling was 3.5 years (+/- 3). The mean score on the CAMCOG was 71 (+/- 12.7). The scores at the first quartile for illiterate/1-4 years of schooling were 58/62 (65-69 years), 52/63 (70-74 years), 48/67 (75-79 years) and 46/64 (> 80 years), respectively. There was a significant difference in the CAMCOG quartiles according to education and age. This study provides normative data on the CAMCOG of elderly people with low educational levels which may be clinically useful.

“…To fulfill the item “b” of the Petersen criteria we assessed the memory performance in the Cambridge Cognitive Examination (CAMCOG) [31]. Because of educational heterogeneity in the sample, normative values suggested by a previous study with 292 elderly subjects in the Alzheimeŕs disease Center of the Federal University of Rio de Janeiro were adopted [37]. Subjects with cognitive performance 1.5 S.D.…”

Can the CAMCOG be a good cognitive test for patients with Alzheimer's disease with low levels of education?

“…A recent study has reported normative data for older Brazilians in the CAMCOG screened for dementia and depression, including illiterates, and seniors with 1-4 years of education, and ≥5 years (Moreira et al, 2009). However, at present, there is no accuracy data for the older population with lower education.…”

Is the Cambridge Cognitive Examination - Revised a good tool for detection of dementia in illiterate Brazilian older adults?

“…The scores at the first quartile for the group formed by illiterate and 1–4 years of schooling individuals were 58/62 (aged 65–69 years), 52/63 (aged 70–74 years), 48/67 (aged 75–79 years) and 46/64 (aged >80 years). These results showed that subjects with low education and older age had worse performance on the CAMCOG test …”

“…In Brazil, Moreira et al . have evaluated with the CAMCOG the cognitive performance of 292 non‐demented elderly subjects with low educational levels . The scores at the first quartile for the group formed by illiterate and 1–4 years of schooling individuals were 58/62 (aged 65–69 years), 52/63 (aged 70–74 years), 48/67 (aged 75–79 years) and 46/64 (aged >80 years).…”
