I look forward to Phase 3 trial results. I think many of us have dismissed the fact that insulin might play a role in dementia, instead looking only at hyperglycemia and its devastating effects throughout the body. We've known that obesity and diabetes harm brain function long-term, without properly considering that low levels of insulin might be damaging to memory or brain function—something that can be corrected more easily than getting a generation of people to stick to their ideal body weight.
