Area of Science:

  • Gerontology and Cognitive Neurology
  • Neuropsychological Assessment Tools
  • Public Health and Global Health

Context:

  • Basic mathematical ability is susceptible to cognitive decline.
  • Existing cognitive tests are unsuitable for illiterate or low-education individuals.
  • The coin test (CT) was developed to address this diagnostic gap.

Purpose:

  • To evaluate the coin test's (CT) utility for diagnosing dementia in populations with low educational attainment.
  • To assess the sensitivity, specificity, and predictive values of the CT in a diverse cohort.

Summary:

  • A study of 211 individuals (114 with dementia) assessed the coin test (CT) for dementia diagnosis.
  • The CT demonstrated high performance with a cutoff of <=7, yielding sensitivity of 0.89 and specificity of 0.92.
  • The coin test is a valid, economical, and well-accepted tool for dementia screening.

Impact:

  • The coin test provides a valuable, adaptable screening tool for dementia in underserved populations.
  • Improved early diagnosis of dementia can lead to timely interventions and better patient management.
  • This research supports the development of accessible diagnostic methods for cognitive impairment globally.
