The victim of an aggressive type of dementia, the 57-year-old businessmen was unable to answer the phone, order a meal or string more than a couple of words together. In desperation, his family agreed to try a revolutionary new treatment - a bizarre-looking, experimental helmet devised by a British GP that bathes the brain in infra-red light twice a day. To their astonishment, Mr Fennel began to make an astonishing recovery in just three weeks.
While the helmet has yet to be proven in clinical trials, the family say the effects of the 10 minute sessions are incredible. Mr Fennell can now hold conversations and go shopping unaccompanied. The treatment is the brainchild of Dr Gordon Dougal, a County Durham GP. He believes the device could eventually help thousands of dementia patients. "Potentially, this is hugely significant," said Dr Dougal, who is based in Easington, County Durham and is a director of Virulite, a medical research company. Developed with Sunderland University, the helmet has 700 LED lights that penetrate the skull. They are thought to be the right wavelength to stimulate the growth of brain cells, slowing down the decline in memory and brain function and reversing symptoms of dementia."
Sounds pretty promising, I'd like to see this lead to a bright future for dementia patients. The article is pretty light on details , though - I admit I don't understand how infra red light penetrates the skull, but then again, my formal biology education pretty much ended with one class in college. It would have been nice if the article could have illuminated me on the exact function.
