Addenbrooke’s cognitive examination III in the diagnosis of dementia: a critical review

Addenbrooke’s cognitive examination III is a screening test that is composed of tests of attention, orientation, memory, language, visual perceptual and visuospatial skills. It is useful in the detection of cognitive impairment, especially in the detection of Alzheimer’s disease and fronto-temporal dementia. The aim of this study is to do a critical review of the Addenbrooke’s cognitive examination III. The different language versions available and research about the different variables that have relationship with the performance of the subject in the ACE-III are listed. The ACE-III is a detection technique that can differentiate patients with and without cognitive impairment, is sensitive to the early stages of dementia, and is available in different languages. However, further research is needed to obtain optimal cutoffs for the different versions and to evaluate the impact of different age, gender, IQ, and education variables on the performance of the test.
