Demographically adjusted normative data among Peruvians with diverse education levels for version 3 of the Alzheimer's Disease Centers' neuropsychological test battery in the Uniform Data Set.

ABSTRACT:

Introduction

Demographically adjusted norms are essential for interpreting cognitive tests, yet none exist in Peru for the Alzheimer's Disease Centers' (ADCs) neuropsychological test battery, especially among low-education populations.

Methods

We assessed 340 healthy adults (ages 43-79, 70% female), balanced by education level (0-6 years, n = 173; ≥ 7 years, n = 167). Participants completed the Uniform Data Set version 3 Neuropsychological Battery (UDS3-NB). Normative values were generated using linear regression with age, education, and sex as predictors.

Results

Education groups were matched for age (p = 0.970) and sex (p = 0.904). Neuropsychological measurements varied significantly between education groups, with education emerging as the primary influential factor
