Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Area of Science:

  • Gerontology
  • Digital Health
  • Neuroscience

Background:

  • Early detection of cognitive impairment is crucial for timely intervention.
  • Smartphone applications offer a promising avenue for accessible cognitive screening and monitoring.
  • The Brain OK app aims to provide a valid digital tool for cognitive assessment.

Purpose of the Study:

  • To evaluate the validity of the Brain OK smartphone application for cognitive performance assessment.
  • To determine if Brain OK can accurately identify individuals at risk of cognitive impairment.
  • To compare the efficacy of Brain OK with a traditional cognitive screening tool, the Montreal Cognitive Assessment (MoCA).

Main Methods:

  • 88 participants over 60 completed both the MoCA and the Brain OK app.
  • Convergent validity was assessed using Spearman correlations, Bland-Altman plots, and regression analysis.
  • Area Under the Curve (AUC) analysis was performed to evaluate diagnostic accuracy.

Main Results:

  • A strong positive correlation (0.9044) was found between Brain OK and MoCA scores.
  • The Bland-Altman plot indicated good agreement between the two assessment methods.
  • Brain OK achieved a high AUC of 0.941 for distinguishing between cognitively normal and impaired groups, with 95.8% sensitivity and 92.5% specificity.

Conclusions:

  • The Brain OK smartphone app is a feasible and acceptable tool for cognitive function assessment.
  • Brain OK demonstrates high accuracy in identifying individuals with cognitive impairment.
  • This digital tool can complement traditional assessments and improve conversations about cognitive health.
