Summary of “The smartphone app that can tell you’re depressed before you know it yourself”

There is something most of those people have in common: a smartphone.
Mindstrong Health is using a smartphone app to collect measures of people’s cognition and emotional health as indicated by how they use their phones.
With details gleaned from the app, Mindstrong says, a patient’s doctor or other care manager gets an alert when something may be amiss and can then check in with the patient by sending a message through the app.
Subjects went home with an app that measured the ways they touched their phone’s display, which Dagum hoped would be an unobtrusive way to log these same kinds of behavior on a smartphone.
Brain-disorder treatment has stalled in part because doctors simply don’t know that someone’s having trouble until it’s well advanced; Dagum believes Mindstrong can figure it out much sooner and keep an eye on it 24 hours a day.
In its current form, the Mindstrong app that patients see is fairly sparse.
“There are people who are high utilizers of health care and they’re not getting the benefits, so we’ve got to figure out some way to get them something that works better.” Actually predicting that a patient is headed toward a downward spiral is a harder task, but Dagum believes that having more people using the app over time will help cement patterns in the data.
About 1,500 of the 2,000 participants also let a Mindstrong keyboard app run on their smartphones to collect data about the ways they type and figure out how their cognition changes throughout the year.
