In 2008, the researchers in Wisconsin, US discovered that PBM (photobiomodulation) is effective on Parkinson’s ( Liang et al., 2008 ). Click to view
Afterwards, researchers in Australia, France and Switzerland published numerous research studies that PBM can reduce the symptoms of MPTP and/or 6-OHDA and alpha-synuclein in the animal model with Parkinson’s (Johnstone et al., 2016 ). Click to view
In 2016, the study on PBM having an effect on monkey model with Parkinson’s has been published in the Annals of Neurology in the American Journal of Neurology. Click to view
In this study, optical fiber devices with visible red light (670 nm) were planted in the brain and MPTP injections were given for a week. In this treatment, the majority of monkeys reversed the symptoms. ( Darlot et al., 2016 ).
Red light (670 nm) was used in this study, but near-infrared light (810 nm) was also used in other studies. Usually light is administered either as a span or as a straight line to the head through percutaneous fibers, but one study suggests that it has a remote neurological protection effect on the brain and that photobiotics may be better represented. ( Johnstone et al., 2014 , Kim et al 2017 ).
