Light Therapy as Treatment for Parkinson’s Disease

Research Reports Light Therapy Reverses Dementia

Light therapy has floated to the top of the list as a promising treatment for Parkinson’s after reviewing results of my 2022 Parkinsons Recovery holiday survey. A surprising number of respondents to the survey reported that low level laser light therapy (or photobiomodulation) helped them celebrate relief from their symptoms.

Light therapy is not new. It has been researched under a variety of terms for over 40 years: low level laser therapy or LLLT, laser biostimulation and most recently photobiomodulation. This noninvasive therapy has been used in clinical practices to treat healing-resistant wounds, ulcers, pain and nervous system injuries. More recently it is a therapy that has attracted the attention of researchers as a therapy for Parkinson’s and Alzheimer’s.

The interview clip below is with Dr. Lew Lim, the CEO of Vielight that has developed several photobiomodulation devices.

A July 2018 a University of California San Francisco study conducted by Linda Chao PhD offered compelling support for its application to treat dementia. Eight adults diagnosed with dementia participated in the study. Four subjects received 12 weeks of self-administered photobiomodulation treatments in their homes. Four were assigned to a control group. Treatments were administered using a commercially available device (Vielight Neuro Gamma). Outcome measures were assessed at baseline, 6-weeks, and 12-weeks.

Findings revealed significant improvement in cognition and functional connectivity. Dr. Chao concluded that photobiomodulation therapy is a safe, non-pharmacological therapy that can be used to treat patients in their homes.

Results of this study are indeed impressive. Large samples are typically required for a study to show significance. Despite its small size, this study showed significant results.

Below Dr. Lim why photobiomodulation is an effective treatment for dementia.

Light Therapy Research

Individuals who responded to the 2022 Parkinsons Recovery survey reported that photobiomodulation (or low level laser therapy) was one of the top five therapies found to be most beneficial. This finding is backed up by a series of research research studies that focus on the beneficial effects of photobiomodulation for individuals diagnosed with Parkinsons Disease.

Since diffuse light does not easily pass through the skull, Dr. Lim’s had the brilliant idea to pass the light through a device clipped to the nose. Now, in my book of creativity, that is inventiveness at its best!

It would seem at this early stage that you cannot go wrong to be open to allow light to shine brightly on the surface of your body and of course your retina!

What has been the experience of persons with Parkinsons symptoms who have been using the Vielight Gamma Device?

Thus far, several hundred persons who listened to my interview on the Vielight device purchased the neuro gamma device using the 10% discount coupon code (healing4me) Dr. Lim provided to listeners of my Parkinsons Recovery Radio Show interview. Those who acquired the device were invited to return the device to the company for a 80% refund after using it for six months if it did not offer relief from their symptoms.

More information is available here:

The company reports to me that 10% of the Neuro Gamma units have been returned. One estimate of effectiveness is that approximately 90% of users are satisfied it helps address some symptoms. The odds are certainly in your favor that the device will be beneficial. Know also that it does not help everyone.

I have also heard from a member of my audience who is connected with a wide community of persons with Parkinsons symptoms. He reports that virtually all users experienced welcome relief from some symptoms. For some, the most pronounced results were seen in the initial 4 months or so, after which the improvements tended to level off.

Anecdotal Reports about the Vielight Photobiomodulation Neuro Device as a Treatment for Parkinson’s Symptoms

Informal feedback from users who are members of my audience is captured below:

  1. One common report from users is that the therapy does not show quick results. You apparently have to apply the therapy over a period of several weeks to a month or longer to celebrate a positive shift in symptoms.
  2. I have heard several specific reports on tremors that were calmed.
  3. It is unclear at this point to what degree the therapy will address balance issues, but I have heard it seems to offer help with gait issues.
  4. Evidence does suggest that this therapy can potentially help with dementia.
  5. One user reported a definite return of smell, but the jury was out on the effect on tremors and other symptoms.
  6. The wife of one 85 year old man with advanced Parkinson’s symptoms reported that after 6 weeks of using the Vielight Neuro device there were no major improvements but several minor ones of some consequence: Her husband reports being more alert, sleeping better, his cough is less, he has been inspired lately to use his automatic peddler and his hallucinations have dwindled. She reports it has been an answer for a better quality of life for both of them and promises to keep me updated.

Of course, it is difficult for people diagnosed with Parkinson’s to attribute an improvement in symptoms directly to the Vielight photobiomodulation therapy when they are taking advantage of other therapies at the same time. Reports above are a general summary of the informal feedback I have received in emails and phone conversations. One person told me it did not offer them the relief they had expected and returned the unit.

Like virtually all natural therapies I have documented over the past several decades, the Vielight Neuro Gamma device will not help everyone. Odds do appear to be in your favor if you decide to try it out.

Dr. Lim has has also invented a device called the X-Plus which delivers light directly to the mid brain. This device is designed to send light to the midbrain which is the location of issues associated with Parkinson’s symptoms.
