That gives a totally new definition to term "propeller head"...
Seeing how "low-level infrared light" is synonymous to thermal radiation, or heat radiation, one has to wonder how in the allmighty spaghetti monster's name is this going to do anything but make your scalp slightly warmer? The brain is pretty the part of body whose temperature is most regulated and stable - it's the last bit to overheat when body heats up, and it's the last place to freeze when you've fallen asleep to snow with half per cent of your bloodstream being alcohol.
There's no way infrared radiation can affect brain cells IN ANY WAY. If it actually does something to brain cells, it does it by some completely different effect than "stimulating brain cell growth" because it can not REACH the brain cells. As far as I know, thermal radiation only penetrates prganic matter slightly deeper than visible light, but all the way down to the brain... I find that a bit far-fetched, to be diplomatic.
If someone knows exactly how deep does deep infrared radiation penetrate organic matter, please illuminate me about the subject. To be effective against Alzheimer (assuming thermal radiation even can stimulate nerve cells to reproduce in the first place), it would need to be able to reach from the surface of skin to the center of the brain, because Alzheimer is caused by beta-amyloid plaques forming all over the brain...
