The Alzheimer's Disease Assessment Scale-Cognitive subscale (ADAS-cog) is commonly used to assess cognitive dysfunction in individuals with Alzheimer disease and other dementias. The purpose of this study was to provide normative scores for the ADAS-cog 11 individual items and total score, as well for delayed recall errors, using normal, elderly volunteers. The ADAS-cog was administered to 124, non-cognitively impaired volunteers ages 55 to 89, with 10 to 21 years of education. The mean total ADAS-cog score was five. The ADAS-cog error score was not associated with education in this highly educated group, and was positively correlated (P < 0.001) with the age of the participant. Age stratified ADAS-cog normative data are reported for the ADAS-cog total and the delayed recall error score.
