Workshop description:
This workshop explores the evolving role of digital ubiquitous technology in cognitive and mental health monitoring. We will examine how wearable and smartphone-based passive assessments, combined with digital self-reports, are transforming research and early intervention strategies.
The session begins with an overview of current and emerging digital health technologies, highlighting their applications in tracking cognition and affective states. Findings from ongoing research at the University of Geneva will showcase how continuous real-world data can provide insights into cognitive function, predict future decline, and potentiate proactive interventions before clinical symptoms appear.
Next, I will introduce Model-Twin Randomization (MoTR), an innovative method for individual-level digital health research. Unlike traditional group-based analyses, MoTR allows researchers to disentangle intra-individual variations from broader population trends, offering a more precise and personalized approach to cognitive health monitoring. This session will explore how such advanced statistical techniques can enhance precision medicine and digital phenotyping.
The workshop culminates in a hands-on session, where participants will work directly with real-world longitudinal data from actual individuals. Using Jupyter Notebook, they will apply MoTR to investigate inter-individual differences in cognitive and mental health patterns, gaining practical experience with real-world longitudinal observational data.
Finally, the session will conclude with an open discussion on the applications of individual-level research methods in academia, healthcare, and industry, and how digital health research can move toward more personalized, scalable solutions for cognitive health monitoring.
