The Times reports on an interview on BBC Breakfast today, revealing how the onset of Alzheimer's disease has started to affect the writing of Terry Pratchett's best-selling fantasy Discworld series.
The author vowed to carry on writing despite having the disease diagnosed last year but revealed that his spelling had become erratic and his typing was no longer as fast - but he says he is trying to be philosophical and remains hopeful that researchers could come up with a means of combating the disease.
“I used to touch type as fast as any journalist does and my spelling was pretty good. Now I hunt and peg and my spelling is erratic," he said.
In March Pratchett gave half a million pounds to the Alzheimer's Research Trust to help to find a cure for the disease. Pratchett's donation inspired an internet campaign where fans hope to 'Match it for Pratchett', by raising an equal sum or more for research.
"I have had Alzheimer’s now for the past two years plus," he states on their web site. "It’s a nasty disease, surrounded by shadows and small, largely unseen tragedies. There's nearly as many of us as there are cancer sufferers, and it looks as if the number of people with the disease will double within a generation. It's a shock and a shame to find out that funding for research is three per cent of that which goes to find cancer cures."
In April, the BBC began working with him to make a documentary series based on his illness.
