Italian version and normative data of Addenbrooke's Cognitive Examination III.

ABSTRACTObjectives:Addenbrooke's Cognitive Examination III (ACE-III) is a brief cognitive screening tool to assess five cognitive domains: attention/orientation, verbal fluency, memory, language, and visuospatial abilities. This study aimed to provide normative data (for total score and subscale scores) of the Italian version of ACE-III for gender, age, and education.

METHODS: A total of 574 healthy Italian participants (mean age 68.70 ± 9.65; mean education 9.15 ± 4.04) were recruited from the community and included in the study. Linear regression analysis was performed to evaluate the effects of age, gender, and education on the ACE-III total performance score.

RESULTS: Age and education exerted a significant effect on total and subscale ACE-III scores, whereas gender was on attention/orientation, language, and visuospatial subscale scores. From the derived linear equation, correction grids to adjust raw scores and equivalent scores (ESs) with cut-off values were provided.

CONCLUSIONS: The present study provided normative data, correction grids, and ESs for ACE-III in an Italian population.
