Parkinson's Disease (PD) affects many women around the world, especially those under 60. Some women with PD notice their symptoms get worse around their menstrual cycle, but there isn't much research or guidance on this. This study aims to track these changes using a mobile app called My Moves Matter (MMM) and a device called PDMonitor. The app helps women record their symptoms and the device tracks physical changes. This information will help doctors personalize treatments for women with PD.

• **Study Duration:** This study will last several months.
• **Participation Requirements:** Participants must be pre-menopausal women with PD, aged 18-56, and on a stable medication plan.
• **Technology Use:** Participants will need to use a mobile app and possibly a wearable device to track symptoms.

The study is being conducted in French and aims to provide better care for women with Parkinson's by understanding how hormonal changes affect their symptoms.
