The Daily Mail reports that fantasy author Sir Terry Pratchett is trialling an experimental Alzheimer’s treatment.

Sir Terry Pratchett has been trialling a revolutionary new device that claims to slow, and even reverse the effects of Alzheimer’s.

The award-winning author, who was diagnosed with dementia in 2007, is one of the first patients in the UK to try the anti-dementia helmet.

The device sends intense bursts of light at a particular wavelength the a patient’s skull.

The prototype device, used for six minutes daily, is supposed to decrease the effects of Sir Pratchett’s ailment, and seems to be working so far. Measurable improvements are being made, according to tests.

Hopefully the Discworld author will see further improvement.
