Design of a Mobile App and a Clinical Trial Management System for Cognitive Health and Dementia Risk Reduction: User-Centered Design Approach.

ABSTRACT:

Background

The rising prevalence of dementia is a major concern, with approximately 45% of cases linked to 14 modifiable risk factors. The European project LETHE aims to develop a personalized digital intervention model to delay or prevent cognitive decline through risk factor management.

Methods

Using a user-centered design approach, workshops and feedback rounds involved potential participants representing the target group and professionals. The LETHE app's usability was assessed among 156 older adults enrolled in a 2-year
