Topic: Risk, prevention and care in population studies
Plain-language summary
Introduction differentiating mild cognitive impairment (MCI) from normal cognition (NC) is difficult. The AB Cognitive Screen (ABCS) 135, sensitive in differentiating MCI from dementia, was modified to improve sensitivity and specificity, producing the quick mild cognitive impairment (Qmci) screen. Objective this study compared the sensitivity and specificity of the Qmci with the Standardised MMSE and ABCS 135, to differentiate NC, MCI and dementia.

Key findings
- The AB Cognitive Screen (ABCS) 135, sensitive in differentiating MCI from dementia, was modified to improve sensitivity and specificity, producing the quick mild cognitive impairment (Qmci) screen.
- Objective this study compared the sensitivity and specificity of the Qmci with the Standardised MMSE and ABCS 135, to differentiate NC, MCI and dementia.
- Methods weightings and subtests of the ABCS 135 were changed and a new section 'logical memory' added, creating the Qmci.
- From four memory clinics in Ontario, Canada, 335 subjects (154 with MCI, 181 with dementia) were recruited and underwent comprehensive assessment.
Why it matters
This study compared a new brief screening tool, the Qmci, with the Standardised MMSE and another screen for telling apart normal cognition, mild cognitive impairment and dementia. Better screening tools could help identify mild cognitive impairment earlier, though this study only assessed test accuracy, not treatment.
