Validation of the Polish Version of Addenbrooke’s Cognitive Examination III in Mild Cognitive Impairment and Alzheimer’s Disease Dementia
Anna Barczak, Anna Krempa-Kowalewska. Dementia and Geriatric Cognitive Disorders, 2026-01-13
Topic: Amyloid, tau and blood-test diagnosis
Internal consistency of the ACE-III was strong (McDonald's ω = 0.889). The ACE-III demonstrated superior diagnostic accuracy compared with the MMSE, with optimal cutoffs of 88.5 (sensitivity, 98%; specificity, 92%) for distinguishing controls from MCI and 72.5 (sensitivity, 90%; specificity, 76%) for distinguishing MCI from AD-D. The ACE-III is a reliable and sensitive tool for detecting early cognitive decline in the Polish population. Its superior diagnostic utility compared with the MMSE, particularly in identifying early neurocognitive impairment, supports its use in timely diagnosis and intervention.

Key findings
- Internal consistency of the ACE-III was strong (McDonald's ω = 0.889).
- The ACE-III demonstrated superior diagnostic accuracy compared with the MMSE, with optimal cutoffs of 88.5 (sensitivity, 98%; specificity, 92%) for distinguishing controls from MCI and 72.5 (sensitivity, 90%; specificity, 76%) for distinguishing MCI from AD-D.
- The ACE-III is a reliable and sensitive tool for detecting early cognitive decline in the Polish population.
- Its superior diagnostic utility compared with the MMSE, particularly in identifying early neurocognitive impairment, supports its use in timely diagnosis and intervention.
Why it matters
The Polish version of the ACE-III showed strong internal consistency and better diagnostic accuracy than the MMSE for distinguishing controls from mild cognitive impairment and mild cognitive impairment from Alzheimer's disease dementia. This supports its use in timely diagnosis, but it is a cognitive screening tool and does not treat or prevent dementia.

How this study scored 42/100
Published in a peer-reviewed journal. Scored zero for study design, effect reported and randomised / blinded because the record does not state it. We have no data on senior author's track record, so that was left out: it earned 40 of the 96 points we could judge it on, which is 42 out of 100.
