**Study Summary:** This study examines how training healthcare workers in nursing homes can improve the **quality of life** for residents with **Parkinson's Disease (PD)**. Parkinson's Disease is a condition that affects the brain and leads to problems with movement and other symptoms. As the disease progresses, these symptoms can change and become more complex. Many nursing home residents with PD have other health issues that make their care challenging. Without proper knowledge and training, healthcare workers may struggle to provide optimal care, which can affect residents' well-being. The study is being conducted in nursing homes in the Auvergne Rhône-Alpes region and focuses on how the training of healthcare workers can lead to better care practices. It will also look at whether trained staff feel more confident and comfortable in their roles, which could improve their work life. **Key Points:** - **Participation:** Must be 18 or older, have Parkinson's, and live in specific nursing homes. - **Timeframe:** The study started in October 2024 and is part of a larger effort to improve care. - **Impact:** The results could lead to better care nationwide and improve both resident and staff experiences.
