High Frequency Light, Sound, and Tactile Stimulation to Improve Motor and Cognitive Deficits in Parkinson's Disease

Parkinson's disease (PD) impacts different types of neural oscillations in the brain, including beta (13-30Hz) and gamma oscillations (30-80Hz), which contributes to PD's cardinal symptoms of resting tremor, rigidity, bradykinesia (slowness of movement), and gait instability. The investigators' lab has developed a non-invasive method of increasing gamma power in the brain using Gamma Entrainment Using Sensory Stimulation (GENUS) through light, sound, and tactile stimulation devices. For this study, 40 participants with mild Parkinson's disease will be recruited, and the investigators will assess their brain waves with electroencephalogram (EEG) before, during, and after light, sound, and tactile stimulation to determine the safety, feasibility, and optimization of GENUS as a potential therapy in the PD population.
