Summary

This study is testing a smartphone app called QbMobile that measures attention, impulsivity, activity, and movement patterns. Researchers want to see if it can provide objective data to help diagnose ADHD in people aged 6 to 60. The study includes 700 participants with and without ADHD, and compares the app's scores to standard diagnostic methods.

What this could mean

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

Active substance
QbMobile (smartphone app)
What this could lead to
If successful, this could provide a reliable, objective tool to help doctors diagnose ADHD more accurately, both in clinics and remotely.
What could go wrong
This is an early validation study, not a treatment trial. The app may not prove accurate enough for widespread clinical use, and results may not apply to all populations.
