Completely arrested? I don't. But it appears to be arrested in ways that matter for mental acuity, for now. I've taken care of a parent with Alzheimer's, and helped several other caregivers over the years with their own family's journeys, and one thing I can tell you is that I have never, ever seen an actual halting of the progression for this long. The descent is usually a stairstep pattern, but the steps are on the matter of weeks to a month or two. My friend has been stable for a year.

This is all new. There is research hinting at Alzheimer's subtypes, some of which are more likely to respond than others. Even halting the decline is a huge potential breakthrough.

I hope there'll be a cure or something that lasts long. It's a horrible disease. Best of luck!
