AI Article Synopsis

  • The study focuses on the Mini-Cog test as an early screening tool for cognitive decline, particularly in the elderly population of Kanagawa Prefecture, Japan.
  • Researchers tested the Mini-Cog through a smartphone app on 40 participants aged 65-85, finding a positive association with professional assessments, though the reliability of repeated tests was affected by learning effects.
  • The app not only assesses cognitive function but also provides guidance on preventing cognitive decline and referrals to medical services if a low score is detected, promoting ongoing health management.

Article Abstract

Objective: Cognitive decline is an important and well-documented health problem. The Mini-Cog, a simple cognitive function test, is recommended as a potential early cognitive screening tool. Kanagawa Prefecture, one of the largest prefectures in Japan, developed this self-testing application on a smartphone to enable a large number of residents to assess their cognitive function. This study aimed to verify the validity and reliability of the Mini-Cog.

Results: Twenty men and 20 women aged 65-85 years were enrolled. Criterion-related validity of the method tested by professional staff was found to have an acceptable positive association. The test-retest reliability was lower than the clinically expected intraclass correlation coefficient value because of the inclusion of learning and order effects. If the Mini-Cog score of this application is low, the system is equipped with a function that advises the users on preventing cognitive decline, directing them to the appropriate services, and recommending visits to a medical institution. Therefore, the system can be used continuously as a tool for health behaviors and promotions.

Objective: This study aimed to assess the practicality and trustworthiness of explainable artificial intelligence (XAI) methods used for explaining clinical predictive models.

Methods: Two popular XAIs used for explaining clinical predictive models were evaluated based on their ability to generate domain-appropriate representations, impact clinical workflow, and consistency. Explanations were benchmarked against true clinical deterioration triggers recorded in the data system and agreement was quantified.

Survey studies are valuable tools that can quickly and cost-effectively collect data from diverse populations across different cultures and locations. When conducted across multiple countries, careful translation and cross-cultural adaptation are necessary to maintain the validity and reliability of the findings. This point is particularly important for patient-facing questionnaires, especially in fields like psychology and sexual medicine.
