Light Therapy for Parkinson’s Disease

Parkinson’s disease is a combination of movement disorders including tremor, muscle rigidity, impaired balance and slowness of movement. It can also cause neurological problems such as depression, poor sleep, memory loss and confusion. Its cause remains a mystery but it is known to be associated with dopamine depletion and loss of neurons in the basal ganglia region of the brain.

The current mainstay of treatment involves physical therapy as well as medications which act to increase dopamine levels in the brain. These medications can provide significant improvements but their effectiveness tends to wear off with time, and they can cause a number of side effects. In addition, they treat the symptoms only, without actually slowing, or reversing, the natural course of the disease.

One avenue of research that has shown unexpected promise is red and infrared light therapy, with a number of studies showing that it may decrease the level of damage and improve motor function in animal testing for Parkinson’s disease.

Retired Tasmanian Federal Politician Max Burr is a sufferer of Parkinson’s who tried light therapy after reading a research paper published by The Sydney University’s Professor John Mitrofanis on the use of photobiomodulation – the term used for light’s ability to modulate key biological processes at a cellular level – in animal testing for Parkinson’s.

“The paper showed that the use of 670-nanometre red light was protective of neurons in Parkinson’s,” Burr said. “So I sent Professor Mitrofanis an email and said, ‘Look, this is all very interesting, I wouldn’t mind having a crack at it’.”

Even though Mitrofanis believed the laboratory results on light therapy showed promise, he had no choice but to tell Burr that all the work was pre-clinical, and he couldn’t recommend it to humans yet. 

Aware that his condition was not going to wait while scientists went through the long process of obtaining approval for human trials, Burr went ahead and built a homemade device from an aluminium-foil-covered lampshade lined with strips of LED bulbs that emitted red light at a wavelength of 670 nanometres. Once completed he started using the device on his head for twenty minutes twice a day.

Burr’s description of what happened is remarkable. “I recovered my sense of smell, my writing is now firm and concise, my gait has improved and I can climb stairs,” he says. “From week to week, it might have only been a subtle change, but the cumulative effect over the months has been quite significant.”

For sceptics, it is certainly possible that Burr’s improvement is at least partially due to the placebo effect. This is especially the case in Parkinson’s, where some placebo treatments have been shown to actually increase the release of dopamine in the brain.

Burr, however, believes there are physiological reasons behind his improvement. “The benefits of the light must be being transferred by a mechanism in the body – either by the vascular system or by the immune system,” he says. 

Dr Daniel Johnstone, a medical scientist and lecturer at The University of Sydney’s medical research centre the Bosch Institute, agrees with Burr’s reasoning.

“The exact mechanisms are still not totally known, but we do know that there’s a key enzyme in the cells that absorbs light at certain wavelengths and triggers this intracellular cascade signalling that seems to collectively lead to a protective effect,” he explains. “Light is actually a low-level stress to the cells, and when you deliver this stress, it either stimulates repair processes or it conditions the cells to upregulate a whole lot of stress-response systems that conditions that tissue against a more severe insult down the line.”

His supervisor at the Bosch Institute is executive director Professor Jonathan Stone. “It is clear to me that the pace of studies on photobiomodulation is increasing exponentially,” Stone says. “Despite a lot of scepticism, people are being drawn into it by the fact that it works. There’s growing evidence that it works against depression and stroke and in the cognitive aspects of Alzheimer’s disease.” 

Encouragingly there have been no known complications from the use of red and infrared light therapy in humans.

“Given the huge health impact of Parkinson’s and other neurodegenerative diseases like Alzheimer’s, and how safe and easily administered light treatment is, I didn’t see what we had to lose by pursuing further research in this area,” Johnstone says. “There’s no guarantee that it will work yet, but I can pretty much guarantee that it’s not going to cause any harm.”

Burr’s geriatrician, Frank Nicklason, is a staff specialist at the Royal Hobart Hospital. He sees many patients with Parkinson’s disease and other neurological conditions. Although he advises prudence he provides research information about light therapy to some of his patients. To his knowledge around a dozen have given it a try.

“Changes are often subtle and tend to be noticed by spouses,” Nicklason said. “Changes that have been reported include a better sense of wellbeing, better sleep, less anxiety and improved mental clarity. Given that non-motor symptoms like anxiety, depression and confusion are major drivers of reduced quality of life, even minor improvements are likely to be valuable.”

Surfers Health Practice Principal Dr Mark Jeffery has been using lasers in his surgery for more than four years. He says the research supports the use of light therapy for a wide range of diseases including Parkinson’s, Alzheimer’s, depression and chronic pain.

“The reality is there are no real side effects from low level laser therapy and it’s one of the safest treatments you can ever do,” he says.  

Burr has been using light therapy for more than three years now and has not required any increase in his anti-Parkinson’s medications. In the meantime his LED unit has received an upgrade. “We’ve made it out of a bucket,” he said. “We’ve also added 810-nanometre lights as well as the 670-nanometre lights. Both LED wavelengths have their own switch. So I do 15 minutes on one wavelength and then 15 minutes on the other.”

Mitrofanis is optimistic about the long-term future of red and infrared light therapy. A career-defining moment came for him when he travelled to Tasmania to meet Burr and other Parkinson’s patients with whom he had been corresponding with.

“It was a wonderful experience,” he said, recalling the emotional meeting where those affected by neurodegenerative disorders shared their stories about how light therapy had improved their lives. “No one can say the light treatment has completely reversed all their symptoms, but they’re all showing signs of improvement.”

  1. I simply wished to say thanks again. I am not sure the things I would have tried without the type of tips and hints shown by you over such a theme. This was an absolute hard concern in my view, but finding out your well-written strategy you handled that made me to weep over gladness. I’m just happier for your service and in addition trust you comprehend what a powerful job you are carrying out instructing people with the aid of your webblog. I am certain you’ve never got to know any of us.

  2. I just finished watching the Kennedy Center Honors today. I guess they gave an award to Linda Ronstadt. Did you see that? I’m so happy for her. She’s been battling Parkinson’s for many years.

  3. Riցht here is the right blog for eveгyone who wishes to find out about this topіc.

    You realize so much its almоst tough to arguе with you (not that I really will need
    to…HaHa). You definitely put a new spin on a topic which has been written about for yeаrs.
    Great stuff, just wonderful!

  4. After was running around from doctor to doctor before we finally get rid of her PD ,at age 74 my mother noticed that her handwriting was getting smaller and I was writing faster as well. She also noticed a small tremor in her left hand. The doctor went over her different symptoms and he suspected she either had a small stroke or the beginnings of Parkinson ‘s disease. After finding a neurologist and some testing she was diagnosed with the beginning stages of Parkinson’s disease. That was 3 years ago. She take Sinimet four times a day to control the symptoms, which include falling, imbalance, gait problems, swallowing difficulties, and slurring of speech,This year, our family doctor started her on totalcureherbsfoundation com PD Herbal mixture, over 3 months into treatment she improved me dramatically. At the end of the full treatment course, the disease is totally under control. No case of dementia, hallucination, weakness, muscle pain or tremors.PD or any other disease natural organic remedies are always work on acidity treatment, if we maintain diet plan and use total cure herbs foundation then we get fast relief from this problem.

    1. Hi Ms Carol Ford
      That’s amazing treatment for PD with herbal mixture for 3 mos
      Where do you buy those herbal mixture ? and how much
      Was it mixed by that doctor seeing you
      My tremors. started Dec 2016 in which day i retired
      The doctor started on Parkinson’s med …. Stalevo , carbidopa levodopa ,entacapone all in one pill which has lots of effects 😩😩😪
      Thanks pls keep in touch

  5. I was suffering from Parkinson’s since 2014 & life had become disastrous for me,75 % of my body was covered by Tremors.After taking product from www .multivitamincare .org under supervision of Dr. Casey, I started getting results within 3 weeks of their dosage .One day I got extremely sick, could not keep anything down, difficulty standing, restless sleep,Started taking this remedies twice daily. I am writing this to inform others that nothing was really working to help my PD other than this product.I went off my previous medications (with the doctor’s knowledge) and started on their Parkinson’s disease herbal formula.Treatment went very well and tremors are gone.
