[Welcome Industry Radar readers!]
Bob tipped me to this:
"An experimental helmet which scientists say could reverse the symptoms of Alzheimer's disease within weeks of being used is to be tried out on patients."
Turns out, a group of British researchers have found that low-level, infrared light apparently stimulates certain brain cells, causing them to regenerate and repair themselves. The theory is that even modest exposure can halt, perhaps even reverse, Alzheimer's symptoms.
While the research is still nascent, it seems to hold a lot of promise. We'll keep you posted.
