Remote Photobiomodulation Treatment for the Clinical Signs of Parkinson’s Disease: A Case Series Conducted During COVID-19

Abstract

Objective: To assess whether remote application of photobiomodulation (PBM) is effective in reducing clinical
signs of Parkinson’s disease (PD).
Background: PD is a progressive neurodegenerative disease for which there is no cure and few treatment
options. There is a strong link between the microbiome–gut–brain axis and PD. PBM in animal models can
reduce the signs of PD and protect the neurons from damage when applied directly to the head or to remote
parts of the body. In a clinical study, PBM has been shown to improve clinical signs of PD for up to 1 year.
Methods: Seven participants were treated with PBM to the abdomen and neck three times per week for 12
weeks. Participants were assessed for mobility, balance, cognition, fine motor skill, and sense of smell on
enrolment, after 12 weeks of treatment in a clinic and after 33 weeks of home treatment.
Results: A number of clinical signs of PD were shown to be improved by remote PBM treatment, including
mobility, cognition, dynamic balance, spiral test, and sense of smell. Improvements were individual to the
participant. Some improvements were lost for certain participants during at-home treatment, which coincided
with a number of enforced coronavirus disease 2019 (COVID-19) pandemic lockdown periods.
Conclusions: Remote application of PBM was shown to be an effective treatment for a number of clinical signs
of PD, with some being maintained for 45 weeks, despite lockdown restrictions. Improvements in clinical signs
were similar to those seen with the application of remote plus transcranial PBM treatment in a previous study.
Clinical Trial Registration number: U1111-1205-2035.

Transcranial Photobiomodulation Treatment Effects in Former Athletes with Repetitive Head Hits

Concussion (i.e., mild traumatic brain injury) and repetitive sub-concussive head hits are recognized by the sports medicine community and society at large as a major
public health concern. Psychiatric and neurocognitive functioning disruption and sleep disturbance are associated with these injuries. Transcranial photobiomodulation (tPBM) has been
proposed as a non-invasive treatment.

Red/near-infrared irradiation therapy for treatment of central nervous system injuries and disorders

Irradiation in the red/near-infrared spectrum (R/NIR, 630–1000 nm) has been used to treat a wide range of clinical conditions, including disorders of the central nervous system (CNS), with several clinical trials currently underway for stroke and macular degeneration. However, R/NIR irradiation therapy (R/NIR-IT) has not been widely adopted in clinical practice for CNS injury or disease for a number of reasons, which include the following. The mechanism/s of action and implications of penetration have not been thoroughly addressed. The large range of treatment intensities, wavelengths and devices that have been assessed make comparisons difficult, and a consensus paradigm for treatment has not yet emerged. Furthermore, the lack of consistent positive outcomes in randomised controlled trials, perhaps due to sub-optimal treatment regimens, has contributed to scepticism. This review provides a balanced précis of outcomes described in the literature regarding treatment modalities and efficacy of R/NIR-IT for injury and disease in the CNS. We have addressed the important issues of specification of treatment parameters, penetration of R/NIR irradiation to CNS tissues and mechanism/s, and provided the necessary detail to demonstrate the potential of R/NIR-IT for the treatment of retinal degeneration, damage to white matter tracts of the CNS, stroke and Parkinson’s disease.

Update on Vielight for Treating Symptoms of Parkinson’s Disease

Dr. Lew Lim discusses his new invention – the X-Plus photobiomodulation device and its potential application for symptoms of Parkinson’s Disease and Alzheimer’s. It can be used in conjunction with the Vielight Neuro Gamma device that many listeners of Parkinson’s Recovery Radio have already been using.

Neurons are cells that contain mitochondria. Photobiomodulation energizes neuronal mitochondria, triggering a cascade of beneficial cellular functions. Potential benefits are neuroprotective effects, self-repair mechanisms, and enhanced function.

Vielight’s patented intranasal stimulation technology and microchip LED technology are innovative tools for brain photobiomodulation. Intranasal photobiomodulation is the most efficient method for light energy to reach the brain. Different from electrical and magnetic stimulation, photobiomodulation uses light energy (or photons) of specific wavelengths and power density to simulate cellular function.

Photobiomodulation Therapies in Parkinsons Disease

I recently aired fascinating interviews on Parkinson’s Recovery Radio about two different types of photobiomodulation therapies (light therapies) as treatments for Parkinson’s symptoms. I believe light therapies are the medicine of the future, so I am hopeful some of you will try one of these options out so we can get an early reading on their effectiveness. The purpose of this newsletter is to explain the difference between the two devices. One is offered by Vielight https://www.Vielight.com (discussed in my radio show October 4th); the other is offered by Erchonia https://www.erchonia.com (discussed in my radio show October 16th). How are the Two Light Therapy Devices Similar?

Preclinical Studies of Transcranial Photobiomodulation in the Neurological Diseases

Photobiomodulation (PBM) takes advantage of red and near-infrared light to induce therapeutic effects on various kinds of diseases, with transcranial PBM (tPBM) attracting most attention on neurological diseases. Displaying a noninvasive superiority over traditional treatment, tPBM is increasingly studied among research groups. Growing numbers of studies have been conducted in the last decade regarding neurological diseases; however, the research objects and lighting parameters among these papers varied from each other. This article introduces the biophotonics nature of PBM, records the experimental parameters of preclinical studies since 2014 and summarizes the application of tPBM on the neurobiological diseases in the past two decades. Under the summarized guidance of parameter setup, tPBM will be shining light in the prevention and treatment of neurological diseases.

Effect of Near-Infrared Pulsed Light on the Human Brain Using Electroencephalography

In our previous study, the low-level laser (LLL) stimulation at the palm with a stimulation frequency of 10 Hz was able to induce significant brain activation in normal subjects. The electroencephalography (EEG) changes caused by the stimulation of light-emitting diode (LED) in normal subjects have not been investigated. This study aimed at identifying the effects of LED stimulation on the human brain using EEG analysis. Moreover, the dosage has been raised 4 times than that in the previous LLL study. The LED array stimulator (6 pcs LEDs, central wavelength 850 nm, output power 30 mW, and operating frequency 10 Hz) was used as the stimulation source. The LED stimulation was found to induce significant variation in alpha activity in the occipital, parietal, and temporal regions of the brain. Compared to the previous low-level laser study, LED has similar effects on EEG in alpha (8-12 Hz) activity. Theta (4-7 Hz) power significantly increased in the posterior head region of the brain. The effect lasted for at least 15 minutes after stimulation ceased. Conversely, beta (13-35 Hz) intensity in the right parietal area increased significantly, and a biphasic dose response has been observed in this study.
