New app aims to stop Parkinson's medication side effects before they start
NCT ID NCT07505394
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a smartphone app, called ICD-Shield, can help doctors adjust Parkinson's medications to prevent impulse control disorders (like compulsive gambling or shopping). About 528 people with early-stage Parkinson's will be randomly assigned to use the app or receive standard care. The goal is to see if the app's risk predictions lead to safer treatment and fewer behavioral side effects over three years.
