Norms for CERAD Constructional Praxis Recall

Abstract

Recall of the four-item constructional praxis measure was a later addition to the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) neuropsychological battery. Norms for this measure, based on cognitively intact African Americans age ≥70 (Indianapolis-Ibadan Dementia Project, N = 372), European American participants age ≥66 (Cache County Study of Memory, Health and Aging, N = 507), and European American CERAD clinic controls age ≥50 (N = 182), are presented here. Performance varied by site; by sex, education, and age (African Americans in Indianapolis); education and age (Cache County European Americans); and only age (CERAD European American controls). Performance declined with increased age, within age with less education, and was poorer for women. Means, standard deviations, and percentiles are presented separately for each sample.
