Light Therapy Intervention in Individuals With Parkinson's Disease

The intervention is a non invasive and safe practice. By delivering low level wavelength red light to the front part of the head, it can increase blood flow in the area treated and improve functioning of the associated regions, potentially improving symptoms.

The intervention is a non invasive and safe practice. Participants will be wearing a helmet that delivered low level light therapy to the brain, and use it for the same amount of time as the treatment group. These participants will however, not receive the actual light and receive a placebo, so the helmet will be off. This is done to control of any potential positive effects of the therapy.
