“…This study provides evidence of a moderate positive rank correlation between the MoCA and RUDAS in an English speaking population (r = 0.571) which is similar to the correlation observed in a sample of English speaking New Zealanders followed up in an outpatient clinic . In addition this study also supports a moderate positive rank correlation in NESB participants (r = 0.61).…”

“…While the study cohort are from a single centre, which may predispose to a sampling bias, other centres have confirmed similar correlations between both tests, suggestive of a broader applicability. 2,8 The strengths of the study included a sample of participants with a similar ethnic background to that published by the local area database, with 16 language groups tested. Healthcare interpreters were used for all NESB participants, and apart from educational level, both language groups had a similar demographic profile.…”

In Australia it is recommended that all older people undergoing rehabilitation have a cognitive screen. We performed a longitudinal study comparing the correlation of two cognitive screening tools – the Rowland Universal Dementia Assessment Scale (RUDAS) and Montreal Cognitive Assessment (MoCA) with discharge outcomes in a geriatric inpatient setting. The RUDAS cut‐off (<23/30) was associated with discharge to a nursing home (sensitivity 52%, specificity 70%). This was also noted with a MoCA cut‐off <18/30 (sensitivity 57%, specificity 69%). Furthermore the association between the RUDAS and discharge destination was independent of its association with the Functional Independence Measure (r = 0.116; P = 0.275) and had a shorter administration time. Both RUDAS and MoCA scores could be used as predictors of discharge destination in a multicultural population.

“…Finally, index assessment was done some time after the reference standard and there could have been deterioration in participants' cognitive function [14], making it more severe and dementia easier to detect. This, as well as the fact that assessors were not blind to dementia status of the participants [40] perhaps accounts for the fact that our screening accuracy values for ACE-III were slightly higher than have been found before [9,27]. Screening accuracy may also have been slightly inflated by the use, in some cases, of the ACE-III or ACE-R in the diagnostic process.…”

“…The recommended cut-off score for screening cognitive impairments related to dementia is 87/88 [9]. Given mixed findings with optimal cut-off varying from 76/77 [27] to 87/88 [9] our cut-off score was exploratory and devised using receiver operating characteristic (ROC) analysis to to calculate an optimal cut-off score for which the Youden's index (sensitivity+specificity-1) was maximized [28] …”

ObjectivesThere is enormous potential to improve brain health and reduce the risk of cognitive decline and dementia based on modifiable risk factors. The Lifestyle for Brain Health (LIBRA) index was developed to quantify modifiable dementia risk or room for brain health improvement. The objective of the study was to investigate the utility of the LIBRA index in relation to cognitive functioning in a midlife to early late‐life sample of New Zealanders.MethodsA subsample (n = 1001) of the longitudinal New Zealand Health, Work and Retirement (NZHWR) study completed face‐to‐face cognitive assessments using the ‘Kiwi’ Addenbrooke's Cognitive Examination—Revised (ACE‐R) in 2010 and again in 2012, in addition to completing biennial NZHWR surveys on socioeconomic, health and wellbeing aspects. The LIBRA index was calculated incorporating information on 8 out of 12 modifiable health and lifestyle factors for dementia. Unadjusted and adjusted regression models and mixed effects models were used to inspect associations of LIBRA with cognitive functioning, cognitive impairment, and cognitive decline.ResultsThe analytical sample (n = 881 [88.0%], after considering exclusion criteria and missing data) had a mean age of 63.1 (SD = 6.5) years, 53.3% were female, 26.2% were Māori, and 61.7% were highly educated. Higher LIBRA scores (indicating higher modifiable dementia risk) were associated with lower cognitive functioning (B = −0.33, 95% CI = −0.52;−0.15, p < 0.001) and a higher likelihood of cognitive impairment (OR = 1.22, 95% CI = 1.04; 1.42, p = 0.013), but did not predict cognitive decline over 2 years (B = −0.03, 95% CI = −0.22; 0.16, p = 0.766), adjusted for age, age2, gender, education, and ethnicity.ConclusionsThe LIBRA index indicated promising utility for quantifying modifiable dementia risk in midlife and early late‐life New Zealanders. For local use, refinement of the LIBRA index should consider cultural differences in health and lifestyle risk factors, and further investigate its utility with a wider range of modifiable factors over a longer observation period.

Performance of three cognitive screening tools in a sample of older New Zealanders

Abstract: All three tools discriminated well overall between cases of mild dementia and controls. To inform interpretation of these tests in clinical settings, it would be useful for future research to address more inclusive and potentially age-stratified local norms.
