Summary
The Greek version of the Addenbrooke's Cognitive Examination-Revised (ACE-R) is a valid dementia screening tool. It demonstrates high accuracy, sensitivity, and specificity for diagnosing dementia in clinical practice.
Area of Science:
- Neurology
- Psychometrics
Background:
- The Addenbrooke's Cognitive Examination-Revised (ACE-R) is a validated bedside test for dementia diagnosis.
- Its high sensitivity and specificity make it a valuable diagnostic instrument.
Purpose of the Study:
- To validate a Greek version of the ACE-R.
- To assess the psychometric properties of the Greek ACE-R.
Main Methods:
- Translation and administration of the Greek ACE-R to 95 participants.
- Study groups included individuals with dementia (n=35) and healthy controls (n=60).
Main Results:
- The Greek ACE-R showed high internal consistency, excellent diagnostic accuracy, sensitivity, specificity, and negative predictive value.
- Positive predictive value was adequate.
- The verbal fluency plus language to orientation plus memory (VLOM) subscore did not effectively discriminate dementia patients in this sample.
Conclusions:
- The Greek ACE-R is a useful brief screening tool for dementia in clinical settings.
- Further neuropsychological evaluation is necessary for differential dementia diagnosis.
