Author Terry Pratchett posted a message on Paul Kidby’s Discworld News website revealing that "I have been diagnosed with a very rare form of early onset Alzheimer’s, which lay behind this year’s phantom ‘stroke.’ We are taking it fairly philosophically down here and possibly with a mild optimism… All other things being equal, I expect to meet most current and, as far as possible, future commitments but will discuss things with the various organisers.  Frankly, I would prefer it if people kept things cheerful, because I think there’s time for at least a few more books yet :o)"

Pratchett went on to reassure readers that any serious consequences of this diagnosis "maybe further off than you think – it’s too soon to tell. I know it’s a very human thing to say ‘Is there anything I can do,’ but in this case I would only entertain offers from very high-end experts in brain chemistry."

Having been enthralled by a TV movie of Pratchett’s novel Hogfather the last couple days (actually our first exposure to the author’s Discworld), we have held him very much in the forefront of our minds, and wish him and his family the best during this difficult time.
