title: The CERAD Neuropsychological Test Battery: norms from a Yoruba-speaking Nigerian sample.
abstract: One-hundred normal, healthy, Yoruba-speaking Nigerian men and women aged 65 and above completed the Consortium to establish a Registry for Alzheimer's Disease-Neuropsychological Battery (CERAD-NB), a cognitive screening battery used in the evaluation of elderly patients with suspected dementia. Correlational analyses indicated pervasive education-influences on test performance. Gender-effects on the CERAD-NB were accounted for by education and there were essentially no age-effects. Education-stratified normative data are presented for all tests. Factor analysis revealed a one factor solution which accounted for 54.7% of the variance.
