Supplementary Material for: Normative Data for the Spanish Version of the Addenbrooke's Cognitive Examination III

<b><i>Background:</i></b> Addenbrooke's Cognitive Examination III (ACE-III) is a cognitive test that has been validated for the diagnosis of cognitive disorders. The aim of this study was to provide normative data for the ACE-III for age, education and gender. <b><i>Methods:</i></b> The Spanish version of the ACE-III was administered to a group of 273 healthy subjects in a multicenter study in Spain. Correlation and determination coefficients for age, education and gender were estimated. The overlapping interval strategy and linear regression analyses were used to provide adjusted norms for demographic factors and to explore the potential influence of these factors in the performance of the test. <b><i>Results:</i></b> Age and education correlated significantly with the total score and with all the domains. Gender correlated only with the domains of attention and visuospatial skills. Norms for the total score and for cognitive domains (attention, memory, fluency, language, and visuospatial skills) are provided. <b><i>Conclusion:</i></b> This study confirms the influence of demographic factors (especially age and education) on the performance in the ACE-III and provides normative data for the Spanish version of the ACE-III.
