Literacy skills, not just education, may protect against memory decline in elders. Higher literacy levels were linked to better memory retention over time in a study of aging adults.

Area of Science:

  • Neuroscience
  • Cognitive Aging
  • Psychology

Background:

  • Literacy may be a stronger indicator of brain reserve than years of education.
  • Literacy acquisition may alter brain organization, enhancing protection against cognitive decline.
  • Longitudinal studies are crucial to understanding reading ability's role in cognitive reserve.

Purpose of the Study:

  • To determine if literacy skills predict cognitive change in a diverse group of elders.
  • To investigate the protective effects of literacy against cognitive decline.

Main Methods:

  • A longitudinal study of 136 nondemented elders (African American, Caucasian, Hispanic) in New York City.
  • Literacy level assessed using the WRAT-3 reading subtest.
  • Generalized Estimating Equations (GEE) analyses controlled for age and education.

Main Results:

  • Elders with lower literacy levels showed a steeper decline in immediate and delayed word list recall over time.
  • Higher literacy skills were associated with preserved memory function.

Conclusions:

  • Literacy skills appear to be protective against memory decline in nondemented elders.
  • Literacy may play a significant role in maintaining cognitive function during aging.
