Influence of Age and Education on Neuropsychological Tests in Zambia

Abstract

Objective: The purpose of this study is to explore the influence of age, education and reading ability on neuropsychological tests in Zambia.
Methods and Materials: 324 adult participants were recruited from urban and rural areas in Zambia. They had an age range of 19-65 and education range of 5 – 19 years of schooling. The Zambia Neurobehavioural Test battery was administered.
Results and Conclusion: Results showed that all Neurobehavioural test scores had a strong association with education and an inverse relationship with age. Education did not generally offer protection against age-related decline in neuropsychological functioning. Reading level predicted performance on neuropsychological tests better than years of schooling
