"Terry Pratchett, the bestselling author of the Discworld fantasy books, is suffering from a rare form of early onset Alzheimer's.
The author has published a statement on a website calling the diagnosis "an embuggerance". Pratchett, who is 59, says that he is taking the news "fairly philosophically" and "possibly with mild optimism". He adds that the statement, posted yesterday on the website of his illustrator Paul Kidby, "should be interpreted as 'I am not dead'" and says that he expects to meet most current and, as far as possible, future commitments."
