Validity of the montreal cognitive assessment as a screen for mild cognitive impairment and dementia in African Americans.
The validity of the Montreal Cognitive Assessment (MoCA) as a screen for mild cognitive impairment (MCI) and dementia was evaluated in African Americans attending an urban outpatient memory disorders clinic. Eighty one patients ≥50 years old were administered the MoCA and neuropsychological tests. ⋯ Using cutoff scores of ≤24 points for MCI and ≤22 points for dementia, the MoCA had .95 sensitivity and .63 specificity for MCI and .96 sensitivity and .88 specificity for dementia. The MoCA is a valid and cost-effective screen for cognitive impairment in African Americans but with a higher likelihood of falsely classifying persons with NC as having MCI.
