Diagnostic accuracy of a global cognitive screen for Maori and non-Maori octogenarians.

ABSTRACT:

Introduction

We assessed the sensitivity and specificity of the Modified Mini-Mental State Examination (3MS) in predicting dementia and cognitive impairment in Māori (indigenous people of New Zealand) and non-Māori octogenarians.

Methods

A subsample of participants from Life and Living in Advanced Age: a Cohort Study in New Zealand were recruited to determine the 3MS diagnostic accuracy compared with the reference standard.

Results

Seventy-three participants (44% Māori) completed the 3MS and reference standard assessments. The 3MS demonstrated strong diagnostic accuracy to detect dementia with areas under the curve of 0.87 for Māori and 0.9 for non-Māori. Our cutoffs displayed ethnic variability and are approximately 5 points greater than those commonly applied
