This is targeted infra-red light that penetrates the skull and can help with blood flow and brain activity. There have been very small scale trials on the devices available for sale and there's a larger trial going on with a slightly different device. They're made by a Canadian company called Vielight and the device I'm looking at is called Neuro Gamma. It costs US$1,700 but there is an 80% money-back guarantee if you're not satisfied after 6 months, so it seems worth the gamble and I think we're going to give it a go. I will report back! There are a few reviews on Amazon, all of which are very positive, but again it's very small numbers. But I feel if something causes no harm it's worth a try. Although I agree that it's not very appealing having things stuck up the nose so I imagine my mum might kick up a fuss! I've been asking the company questions and they tell me that the only difference between the Neuro RX Gamma and the Neuro Gamma is the Neuro RX Gamma will be manufactured in a manner that’s compliant with medical device standards and is subject to success the pivotal clinical trial. However, the parameters are exactly the same and they are deemed safe by the FDA. They’re also currently being registered as a class 2 medical device.
