My elderly aunt, who is 88 now, has Alzheimer's and while she's declining in cognitive ability now that her doctors have figured out her medications and dealt with some psychological issues her rate of decline has improved. The idea of somehow reversing her disease, or at least some of the major symptoms, is intriguing but there's got to a point where the treatment, however well-intentioned, isn't worth it.

But I can see the appeal for someone 30 years younger facing early-onset Alzheimers.
