Light Therapy Intervention in Individuals With Parkinson's Disease

Recruiting now · Not applicable · Has a placebo group

Conditions studied: Parkinson Disease

In brief

The study looks to investigate the effects that light therapy delivered to the frontal cortex could have on Parkinson's disease related symptoms ( both cognitive and motor). The therapy is a non invasive technique that deliverers low level wavelength light to the front part of the head for 12 minutes. for this study the therapy will be done 3 times a week for 6 weeks. To measure the potential effects on the therapy in Parkinson symptoms, we will do a set of cognitive and motor test before and after the intervention to measure any changes as well as control for any potential markers such as age, sex, disease level, medication and exercise.
