Which part of the Quick mild cognitive impairment screen (Qmci) discriminates between normal cognition, mild cognitive impairment and dementia?

Differentiating MCI from normal cognition and dementia was the topic of an article by O’Caoimh et al. (2013) who tested the assessment tool, Qmci. They were interested in comparing the sensitivity and specificity of the subtests of the Qmci to determine which were best in differentiating MCI from normal cognition and dementia. They were also keen to refine and shorten the instrument.
