Does the Addenbrookes Cognitive Examination-revised add to the Mini-Mental State Examination in established Alzheimer disease? Results from a national dementia research register

International Journal of Geriatric Psychiatry, 05/07/2012

The Addenbrooke's Cognitive Examination–revised (ACE–R) and Mini–Mental State Examination (MMSE) total scores are highly correlated. In this clinical sample of people with established AD, for an MMSE score of 24, the predicted ACE–R score was 67.9 with 95% confidence intervals of 61.6–75.4. The extra non–MMSE ACE–R items improve estimates of cognitive ability by 16%.
