A Study To Assess The Feasibility Of Indivi Mobile Application In Monitoring Cognitive Performance In Aging Population

Indivi AG

Start Date

9/1/2025

Completion Date

6/1/2026

Summary

The goal of this observational study is to evaluate the functionality and usability of Indivi mobile application-based cognitive activities in people with mild cognitive impairment/mild Alzheimer's disease (PwMCI/AD) and healthy controls (HC). This application uses a dynamic difficulty adjustment (DDA) system that customizes the level of the cognitive activities to each user. The main questions it aims to answer are: * Does the DDA system reach a stable difficulty level at the same rate for both PwMCI/AD and HC? * Is the stable difficulty level reached by the DDA system different for PwMCI/AD compared to HC? Researchers will also compare cognitive activities results and other aspects of the mobile application's performance to see if the application can validly distinguish between the two groups. Participants will use the Indivi mobile application, with its embedded DDA system, for a 6-week period.

Eligibility Criteria

Age Range: 50 years to 90 years
