This study is about understanding how light therapy might help people with Parkinson's disease. Parkinson's disease affects the brain and can make it hard for people to move or think clearly. Light therapy is a treatment where a special light is used on the front part of the brain, called the frontal cortex, for 12 minutes each session. It’s safe and doesn't hurt. The study involves having this therapy three times a week for six weeks.

Before and after the therapy, doctors will test how well participants can move and think to see if they get better. They will also consider things like age, sex, and level of the disease. This study is only for people who have been diagnosed with Parkinson's disease and who can follow the study's requirements. People who have other serious health issues, cannot give consent, or have certain medical devices can’t participate.

• The study lasts for 6 weeks with 18 therapy sessions.
• Participants will have tests before and after the therapy.
• People with certain health conditions cannot join.

If you or someone you know has Parkinson's, this study might be an opportunity to explore new treatments.
