In his note to fans, Mr. Pratchett seems optimistic. But the last sentence of his note caught my eye:
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.
I can't imagine how horrible he must feel. But there's a group of people who can. If Mr. Pratchett were to contact members of DementiaUSA, DASNI and forMemory, he would find the ultimate experts in living with early stage dementias. They have ideas about staying engaged in life, managing symptoms, and yes, even brain chemistry. Don't you think he's missing out on the best source of information?
