Area of Science:

  • Neuroscience
  • Public Health
  • Gerontology

Background:

  • Dementia poses a growing challenge in India, a country with significant diversity.
  • Dementia is a complex disorder influenced by genetics and environmental factors like nutrition.
  • Lifestyle interventions targeting risk factors may reduce dementia incidence.

Purpose of the Study:

  • To assess dementia risk using the Cardiovascular Risk Factors, Aging, and Incidence of Dementia (CAIDE) score.
  • To compare dementia risk between urban and rural populations in India.

Main Methods:

  • A community-based cross-sectional study involving 471 healthy individuals (50-90 years old) near Hyderabad, India.
  • Data collected included age, gender, education, BMI, physical activity, blood pressure, and cholesterol to calculate the CAIDE score.
  • The CAIDE score was optimized for the Indian population, with a score ≥9.0 indicating dementia risk.

Main Results:

  • 40% of participants (n=189) had a CAIDE score ≥9.0, indicating predicted dementia risk.
  • Individuals in rural areas exhibited a higher proportion at risk (56%) compared to urban areas (28%).
  • Significant differences in education levels were observed between urban and rural cohorts.

Conclusions:

  • The study identified a higher prevalence of dementia risk in urban Indian cohorts compared to rural ones.
  • Findings underscore the necessity of developing region-specific lifestyle interventions for dementia prevention due to India's diversity.
