I didn’t intend to write a book about Parkinson’s disease…I write about Parkinson’s, because it will dominate my own experience of life’s last chapter, so of course I’ve been giving it plenty of thought since I was diagnosed in 1993, twenty-three years ago.
Having Parkinson’s is very much like growing old. The two usually arrive together, although occasionally Parkinson’s strikes much earlier, or moves faster. Michael J. Fox was thirty when he learned that he had Parkinson’s. As for the other diagnosis, old age: We don’t need any tests. We can give that diagnosis to you right now: You’ve got it, it’s progressive, and (unlike Parkinson’s) it’s invariably fatal.
