Summary

Stanford University is developing a mobile app that uses video of a simple physical test (the Short Physical Performance Battery) to assess physical and cognitive function in older adults. The study will collect video data from 30 healthy volunteers to train the app's AI. The goal is to create an accessible, automated tool that could help detect early signs of Alzheimer's disease and related dementias.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
SPPB++ mobile application (diagnostic test)
What this could lead to
If successful, this app could provide a simple, objective way to detect early signs of cognitive decline and Alzheimer's disease using a smartphone.
What could go wrong
This is a very early, small study (30 healthy adults) focused on app development, not testing a treatment. It may not translate to real-world use or benefit patients directly.
