Area of Science:

  • Gerontology and Public Health
  • Neuroscience and Aging
  • Epidemiology

Background:

  • Dementia incidence in South Korea is high, affecting 18.8 per 1,000 elderly individuals and increasing with age.
  • Mild cognitive impairment impacts 22.7% of individuals aged 65+, highlighting a significant public health concern.
  • Effective dementia prevention and management strategies are crucial due to associated functional limitations and dependency.

Purpose of the Study:

  • To identify population-specific, modifiable cognitive reserve markers in the South Korean population.
  • To determine the protective effects of these markers against mild cognitive impairment and dementia.
  • To inform Korean-specific brain health initiatives.

Main Methods:

  • Prospective cohort study using Korean Longitudinal Study of Aging data (2006-2020).
  • Analysis of 10,254 individuals aged 45+ on cognitive reserve indicators and cognitive health outcomes.
  • Inclusion of sociodemographic and modifiable risk factors as covariates.

Main Results:

  • Descriptive analyses will examine dementia and mild cognitive impairment incidence across cognitive reserve markers.
  • Cox proportional hazards regression will quantify the association between cognitive reserve and cognitive decline risk.

Conclusions:

  • The study will identify actionable, modifiable cognitive reserve markers.
  • Findings will contribute to evidence-based dementia prevention strategies in South Korea.
  • Results aim to promote cognitive health and brain health initiatives tailored to the Korean population.
