What is Addenbrooke's Cognitive Examination - III (ACE-III)

The Addenbrooke's Cognitive Examination - III (ACE-III) is a trusted screening tool that helps clinicians detect signs of cognitive impairment and dementia. Replacing the older ACE-R, this detailed assessment evaluates five primary cognitive domains to provide a clear and thorough snapshot of a patient's mental function. It specifically checks attention, memory, fluency, language, and visuospatial skills. The total score is out of 100, where higher numbers suggest better cognitive health, and specific thresholds help identify potential issues like Alzheimer's disease or other deficits. Clinicians can administer the test in roughly 15 to 20 minutes, making it practical for busy clinics. It is available in multiple languages and is free for clinical use. This flexibility allows healthcare teams to track changes over time and plan better support for patients facing memory loss.

ACE-III Scoring

The Addenbrooke's Cognitive Examination III can be scored using two main evaluation approaches. 1. Total Score: Clinicians sum points from Attention, Memory, Fluency, Language, and Visuospatial tasks for a maximum of 100. Higher numbers mean better function. 2. Cutoff Analysis: A total score below 88 usually points to cognitive impairment, while scores under 82 strongly suggest dementia. It's important to review individual domain subscores too, as this helps spot specific weaknesses and tracks a patient's progress in clinical settings.
