[Simple screening test for dementia in elderly persons the time and charge test]

Area of Science:

• Gerontology
• Neurology
• Public Health

Context:

• Dementia presents a significant public health challenge, particularly among the elderly, necessitating early and efficient detection methods.
• Current screening tools for dementia are often complex and time-consuming, limiting their practical application.
• Early diagnosis of dementia is crucial for initiating treatment, facilitating patient referral, and providing support for families.

Purpose:

• To adapt and evaluate the efficacy of the Time and Charge Test for screening dementia in the Japanese elderly population.
• To assess the sensitivity, specificity, and predictive values of the adapted Time and Charge Test.
• To determine the reproducibility and inter-observer agreement of the screening method.

Summary:

• An adapted Time and Charge Test was administered to elderly individuals in Japan.
• Performance metrics including sensitivity and specificity were evaluated against established dementia scales.
• With time limits, the test demonstrated high sensitivity (87.7%) and good specificity (57.1%), suggesting utility in identifying potential dementia cases.

Impact:

• The developed screening method is simple, potentially reducing the burden of early dementia detection.
• Improved screening can lead to earlier intervention, better patient outcomes, and enhanced support systems for affected families.
• This tool could be valuable for healthcare professionals in identifying individuals who may require further cognitive assessment.
