Light Therapy in Parkinson's Disease: Towards Mechanism-Based Protocols

Trends Neurosci. 2018 May;41(5):252-254. doi: 10.1016/j.tins.2018.03.002. Epub 2018 Mar 24.


A growing body of work is investigating the safety and efficacy of light in Parkinson's disease (PD). Here we discuss the potential of this emerging therapy to improve both motor and non-motor symptoms of PD. We also highlight directions for future basic, translational, and clinical research that are critical for the development of mechanism-based protocols of light therapy in PD.

Keywords: bright light; chronotherapy; non-motor symptoms.
