If you use lasers on the brain other than the Erchonia lasers, this is a MUST read for you to be able to understand safety parameters especially if you are lasering kids.
The reason I say “other than Erchonia” is because the Erchonia lasers are non thermal and do not have a thermal impact on the brain in kids or adults, and do not impact even the skin with a temperature increase.
If you use any other laser, especially one that claims to have Class 4 power, or calls itself a Class 3 yet can clock in at 1400 mw, you need to read this.
I recently saw a lecture from a neuro seminar where a dr was talking about the dose in joules at the target tissue in the brain vs what the dose was at the surface and that at the deep target in the brain the dose was only 8 J/cm2, which is within the accepted guidelines.
What blew my mind was that he totally ignored what was happening at all the tissues in between the target and the skin, where the dosage was far exceeding accepted dosing by the WALT. In fact, the dosing at the skin was in the range where you can get an increase in inflammation, a bad increase in ROS, and potential damage to tissues.
Add on top of that is potential thermal impacts from the skin to certain depths in the brain, especially in children where the bone is not as thick and the distances not as great. Temp increases of just 10 degrees Celsius have been shown to be detrimental to the patient.
This study on infrared lasers for imaging shows how much just a 100 mw or 200 mw laser can increase temp at different depths in the brain. They show that the higher the power and the spot size the greater the thermal impact. Now, some will say “but these lasers were used for imaging not therapy!” True, but regardless of the goal, it is still a laser on a brain and both can trigger thermal impacts. This was non-pulsed, continuous wave laser.
My main point is whatever laser you use, you are obligated to understand this research and figure it out for YOUR laser to be safe. I have seen some really great drs who know a ton about neuro stuff not have a darn clue about laser physics and risks and give out treatment recommendations that could be harmful.
This is a bit technical but it may be worthwhile for you to look at it.
Are Red Light devices just as good as a True Laser for Brain support?
This quadruple blind, crossover study an kids with autism compared the effectiveness of a visible red, 635 nm laser vs 635 red light LED device of identical parameters.
Kids in each group got the identical dose of joules and photons.
There was no change in outcomes from the LED group except for a few kids who were a little worse.
In contrast there was statistically significant change in the laser group in outcomes like less irritability, inappropriate speech, hyperactivity, social withdrawal, lethargy, and stereotypic behavior.
The kids from the LED red light group were then given the laser trials 6 months later and got the same results.
This shows that photon per photon, there is a big difference between lasers and LEDs.
The unfortunate thing about these results is they worked too well so the FDA has been sitting on it for 5 years and hasn’t granted approval yet, probably due to how it will cut into pharma sales.
Here is the link to the study, and you can see the chart results in the pics.
