Brain & Nerve Health

How does RLT help?

 

There appears to be neuroprotective effects of laser and light-emitting diodes (LED) in diverse neurological conditions, such as traumatic brain injury (TBI), ischemic stroke, Alzheimer’s disease, Parkinson’s disease, as well as age-related cognitive decline. Besides these therapeutic effects at the molecular level, there is also considerable evidence of changes occurring at the behavioral level such as cognitive enhancement, antidepressant effects, and improved sleep.

The Brain

The brain, along with the heart and muscle, are the tissues with the greatest mitochondrial density. Mitochondria, which are extremely important for our health, longevity and energy production, respond exceptionally well to red/NIR light. Thus, the brain and overall cognitive function (ie. Alzheimer's disease) has a great capacity to heal with RLT.

It is believed that impaired cerebral vascular perfusion is the one of the first manifestations of most brain disorders. RLT can increase the neuronal nitric oxide content, increase the vessel diameter, and improve cerebral blood flow (CBF). Therefore, it could be considered that RLT of specific areas of the brain potentially affects regional CBF.

Nerves

Like the brain, the nerves benefit from enhanced mitochondrial function that helps improve energy production. This increased energy leads to accelerated regeneration of injured peripheral nerves along with improved axonal number and distance of nerve axon regrowth.

What does the research show?

"Transcranial laser therapy (TLT) showed an increase in ATP levels, mitochondrial function, and c-fos suggesting an overall improvement in neurological function. These studies suggest that TLT is a potential candidate for treatment of Alzheimers disease.”

"This treatment (near-infrared light) also significantly reduced dopaminergic neuronal loss in the injected substantia nigra and preserved dopaminergic fibers in the ipsilateral striatum. These beneficial effects were sustained for at least 6 weeks after discontinuing the treatment. Together, our data point to photobiomodulation as a possible therapeutic strategy for the treatment of Parkinson's Disease and other related synucleinopathies.."

**While the current scientific research seems to indicate many positive benefits of RLT in relation to brain and nerve health, there is still an appreciable necessity for more extensive research to be conducted in this area, including double-blind RCT (randomized controlled trials), to provide a more comprehensive, robust overview that will further elucidate the optimal parameters and appropriate uses of RLT, which will ultimately lead the most safe and efficacious uses for individuals dealing with brain and nerve disorders.

Suggested use of RLT for

Brain & Nerve Health 

Ideal frequency:

3 - 7x/week

Treatment time

Stroke & TBI

2 - 7 min. @ 6" away

Peripheral Nerve Injury:

45 - 75 min. @ 6" away, daily for 1 - 2 weeks

Spinal Cord Injury

3 hours @ 6" away, daily for 1-2 weeks

Light:

NIR only, as NIR penetrates deeper than red light. In order to reach the brain tissue, NIR light is required and red light does not add any additional benefit.

*For optimal results, we recommend no more than 15 - 20 minutes of total treatment time per day
