I've been nibbling at the edges of this for a few weeks now. Since I'm not trained in science, I circle around and pick up crumbs until I begin to get a cohesive picture. I've read a few good articles about the relationship between Huntington's, Parkinson's and Alzheimer's. The thrust of the articles seems to be not a cure, but a treatment to modify symptoms. And this seems, in some research, to indicate turning off the signaling that causes the cells to behave in a way that's pathological. I lack the vocabulary to describe what I so far understand, but will acquire that vocabulary in time --I hope. You see why your article was interesting to me. It's one more, really big crumb on the trail :) Here's an article I picked up today, and will save, because of clues laid out in your blog.
I'm pretty sure I'll write about Huntington's in some fashion...but what will I say? Still a mystery to me 😄
