The Pace of Memory Decline in Older Adults without a Neurocognitive Disorder: Results from 22 Years of Follow-Up in a Nationally Representative Sample.

ABSTRACT:

Introduction

The pace of cognitive change is one of the major questions in cognitive aging. The Children of the Depression Age (CODA) cohort of the Health and Retirement Study (HRS) is uniquely suited to study cognitive aging because it has a long follow-up (22 years) and a narrow age range at baseline (67-74 years) and presents a unique opportunity to study this topic.

Methods

We examined delayed recall data over the 22 years of follow-up in a nationally representative sample of the USA (HRS-CODA; N = 2,295 at baseline and N = 263 at the final follow-up wave), examining results for the entire sample and omitting participants with self-reported dementia. Data were analyzed using latent growth curve models, adjusting for baseline age, sex, years of education, and race/ethnici
