Transcranial lights are the way to go.

Here’s a new journal article from the Journal of Alzheimer’s Disease. I’m a co-author, but don’t let that get in the way.

This article looks at the animal and clinical evidence for the use of transcranial and intracranial red and near infrared light devices. There is a lot of detailed information, including and in-depth description of the effect of transcranial red and near infrared lights in people with Parkinson’s disease.

As for which is best – intracranial or transcranial? The verdict is that neither is best on its own. The best is having both working together. It makes sense, having light shining from inside and outside the brain.

Alas, you might be waiting a while before you get access to an intracranial light implant (think DBS with a 670nm LED light), but you can use transcranial lights right now. You can make your own (instructions are here) or look at the Duo Coronet (link is here) .

Meanwhile, have a read…

Research summary

I was asked today if ongoing research into the effects of red and near infrared light on Parkinson’s disease is validating the early observations.

The short answer is yes.

The long answer is most definitely yes!

Here are links to recent blog posts with recent research information from the peer-reviewed medical literature.

2019 – early results from a clinical trial – here

2019 case study journal article – here

2019 clinical trial – specifically looking at changes in motor or movement symptoms – here

Case study research – just published

Hot off the press is a peer-reviewed journal article describing the observations of people with Parkinson’s disease using transcranial red and near infrared light hats on a daily basis.

The title of the article is a hoot: The “Buckets”: Early Observations on the Use of Red and Infrared Light Helmets in Parkinson’s Disease Patients.

The authors are: Catherine L. Hamilton, Hala El Khoury, David Hamilton, Frank Nicklason, and John Mitrofanis.

The article is published in: Photobiomodulation, Photomedicine, and Laser Surgery.http://doi.org/10.1089/photob.2019.4663

It really does work…

I can understand the skepticism about the biological effect of red lights, because that’s where I started from. It seemed too good to be true. However, there is a wealth of excellent quality research out there, and the evidence is compelling that red and near infrared lights protect existing neurones, and can stimulate new neurones to be created, stimulate blood vessels to increase connections- neuroprotection, neurogenesis and angiogenesis.
