ABSTRACT
This chapter is a comprehensive reference manual providing information on the Addenbrooke’s Cognitive Examination – Revised (ACE-R), which is an objective, clinician-administered test with two aims: the reliable detection of the early stages of dementia, and differentiation among dementia subtypes, specifically, Alzheimer’s disease versus frontotemporal dementia. Development of the original ACE arose in response to the need for a cognitive screening test to distinguish among dementia subtypes, as well as to detect subtle impairments. The ACE/ACE-R represents one of the new generation of cognitive screening tests. A brief history of the instrument's development is provided, along with a description of item content and administration/scoring procedures. Psychometric properties are reviewed and a critical commentary is provided. Key references are cited and in most cases the actual scale is included, giving the reader easy access to the instrument.
