“I have a feeling it’s probably the oxygen story (the lack of oxygen in the brain),” she says. “It’d be important to find out if you treat anemia, does that reduce your likelihood of developing dementia? Obviously, that’s not ethical, because you’d want to treat everyone. But there’s got to be a back-door way to get at that question.”
