Cassandra Jardine in The Telegraph:
has an honour been more richly deserved than the knighthood that Terry
Pratchett accepts today from the Queen. His fantasy novels are not to
every taste, but the work he has done over the past year in a very
different field has been both heroic and of universal
This second career began
in December 2007 when, aged 59, he was diagnosed with posterior
cortical atrophy, a rare form of Alzheimer’s, which he described with
comic disrespect as an “embuggerance”. Until Pratchett discovered that
his brain was atrophying, dementia was discussed, if at all, with
resignation. Pratchett was different. He went on the attack. When his
wife said that at least it was better than having a brain tumour, he
said he would rather die of cancer, like his father, than have an
illness that “strips away your living self, bit by bit”.
It enrages him that Viagra is easier to get on the NHS than a drug to slow the progress of dementia.
