INTRODUCTION

Home-based digital sensing can detect changes in activity but often lacks contextual meaning for research or care

Current systems may not capture variability in the physical and social home environment

We need scalable, low-burden technologies that reflect the real-world lived experience of people with dementia

Combining wearable and environmental sensing may provide richer, context-aware insights

We combine wearable

CLINICAL STUDY

EFFECT-AD “Digital Health Pilot” in 30 homes/60 study participants

Three cohorts

Beacons are set up in participants’ homes during technical visit (figure 2)

Real time visibility of compliance and device health

Bracelets recharged and raw data remotely transmitted weekly

Analysis pipeline combines data from wearable sensors and environment beacons. Step count and activity level algorithms from UK Biobank1,2.

Project goals include NACC data integration. 

PRELIMINARY RESULTS

Successfully collected multi-person, concurrent data in shared home environments.

Enables:

Environmental data allows:

Operational findings:

Example from Dyad in the MCI due to AD cohort: interim analysis after 50 days of data collection shown in figures 3-5.

CONCLUSIONS

Integrated wearable + environmental sensing enables:
