BEST-SELLING author Sir Terry Pratchett has launched a new blog about dementia and science.

Sir Terry has written a personal reflection on society's response to dementia and his own experience of Alzheimer's to launch a new blog for Alzheimer's Research UK.

In the inaugural article, he reflects on fear, funding and “pussy footing” around dementia.

He writes: “There isn't one kind of dementia. There aren't a dozen kinds. There are hundreds of thousands. Each person who lives with one of these diseases will be affected in uniquely destructive ways. I, for one, am the only person suffering from Terry Pratchett's posterior cortical atrophy which, for some unknown reason, still leaves me able to write - with the help of my computer and friend - bestselling novels.

“There is no clearly plotted pathway to the course of these diseases. Dementia attacks those facets which make us who we are, and it's a deeply personal attack that defies prediction. And that's the point. Every person with dementia has a unique story to tell, and words need to be put down before they run dry or run out.”

He goes on to call for further investment in dementia research.

The charity's new blog, available to read at, will share the ideas and experiences of people living with dementia, scientists working to improve diagnosis, prevention and treatment, and the fundraisers who support the charity.

Sir Terry became a patron of the charity in 2008, shortly after announcing his diagnosis of a rare variant of Alzheimer's disease affecting vision.
