#2 isn't necessarily so even. They said the effects lasted at least 6 months, not "only". I haven't read the study, but it sounds to me that it was 6 months of success then publish.

Yes, and consider how an animal that lives only 2 years gets Alzheimer's in the first place. They must be genetically engineered to have super turbo Alzheimer's. Normal Alzheimer's doesn't progress so fast I think.

This is a really important thing to keep in mind with these studies, we don't actually know that we're curing Alzheimer's in these mice. We don't even know if mice really get Alzheimer's in the way we do. What we're curing is mice who've been genetically modified to overproduce a protein that's associated with Alzheimer's, and we think that's a good model because the overproduction seems to cause symptoms that look like what Alzheimer's would look like in mice, but it's still just a model.

You DNRTFA. It explains that there are test strains of mice with a genetic condition that predisposes them to Alzheimer's-like conditions.

As always, there's no guarantee that it will work IRL on Homo sapiens.

Also, lab mice only live for ~2 years. A study of mice for significantly longer than that doesn't make sense.
