anti-Alzheimer's helmet?

No one can say Terry Pratchett isn't trying everything to combat his diagnosis of Alzheimer's.  He's testing out a new, experimental helmet that is supposed to halt or slow the progression of the disease.

Science fiction writer Sir Terry, 60, who was diagnosed with early-onset Alzheimer’s in 2007, wore the strange-looking headgear once a day for three months and noticed a small improvement, his agent confirmed.

The prototype anti-dementia helmet, which must be worn for ten minutes each day, was designed by British GP Dr Gordon Dougal. It works by directing intense bursts of infrared light into the brain to stimulate the growth of brain cells. Low-level infrared is thought to encourage cell growth in tissue and encourages it to repair.
