**Study Summary:** Parkinson's Disease (PD) is a condition that affects the brain and can cause movement problems. Apart from these, many people with PD also suffer from a condition called apathy. *Apathy* means a lack of interest, motivation, or feeling, making it hard for patients to do daily activities. This study is exploring if listening to music can help reduce apathy in people with PD. Music has been shown to make people feel good and motivated, possibly by affecting certain areas in the brain responsible for reward and motivation. **Key Points:** - **Study Duration:** Participants will need to engage in music therapy sessions over a period of time to see the effects on apathy. - **Eligibility:** Participants must have a clinical diagnosis of Parkinson’s Disease but cannot have other neurological conditions or metal implants. - **Risks/Compensation:** Details on risks and compensation are not provided, but participating may help improve understanding of music therapy benefits. This study aims to see how music can change brain activity and improve motivation in PD patients. Participants will be part of a research effort to find new ways to enhance quality of life for those with PD.
