People who have type 2 diabetes are about twice as likely to get Alzheimer’s, and people who have diabetes and are treated with insulin are also more likely to get Alzheimer’s, suggesting elevated insulin plays a role in Alzheimer’s. In fact, many studies have found that elevated insulin, or “hyperinsulinemia,” significantly increases your risk of Alzheimer’s. On the other hand, people with type 1 diabetes, who don’t make insulin at all, are also thought to have a higher risk of Alzheimer’s. How could these both be true?

They all have insulin - the T1's just have all of theirs injected, whereas the T2's have their own insulin, plus injected insulin.
I doubt that the T1's insulin levels are being kept low, certainly not ketogenic low, and not really LC-low either. A friend's little girl was diagnosed with T1 when she was about 5 or 6 years old (she's in her late 20's now), and at the time, I was appalled by how many carbs my friend was being told to feed her daughter - bread, crackers, potatoes, with only a little protein because of course she was told that her daughter still needed a minimum of 130 g of carbs daily for brain function. She was actually told that her daughter was allowed to eat cake, as long as the frosting was scraped off, which shows a total disconnect with the fact that the carb content of a piece of non-frosted cake is about twice as much as the carbs in the frosting they scraped off the cake -obviously because of fat phobia, because it sure wasn't in the interest of keeping her carb consumption low.
In another instance, I know of someone who's daughter was diagnosed as T1 when she was a little older. She was of course in the hospital to have her blood sugars stabilized because this newly diagnosed T1's blood sugars were totally out of control. But what did they feed her the entire time she was there? Hot dogs and hamburgers, served on buns, which was more carbs than she was being fed at home.
Little wonder than that in both cases, keeping the child's blood sugar under control was extremely difficult, especially the first couple of years when suddenly the pancreas would work again for a few hours or a day or two, and overdo it - it was a roller coaster ride. Her blood sugar would suddenly drop like a rock to dangerously low levels, then her blood sugar would suddenly rocket way up to 400, 600, or more, despite eating exactly what she was being told to eat, and injecting the "proper" amount of insulin for what she'd just eaten, so attempting to keep the numbers at a more reasonable level required additional insulin or glucose tablets to raise her blood sugar quickly. Or switching back and froth between both, if it didn't stabilize somewhere in an acceptable range (stabilized blood sugar for a T1 at this early stage is nothing at all like a normal blood sugar reading - getting it down somewhere below 200 was more than acceptable).
I don't know what's going on with the other little girl (lost contact with her a few years ago), but within a couple of years of the local little girl's diagnosis, she was put on an insulin pump, which did a better job of stabilizing blood sugars, but that's primarily because instead of injecting a large amount to cover all the excess carbs she'd eaten over the previous few hours, they cold enter the carb numbers into the pump programming every time she ate, and it would give her the right amount to cover that particular meal or snack. I haven't had as much contact with my friend since her daughter hit her teens, so I don't know for sure if she has one of the devices that senses blood sugar levels, and communicates with an insulin pump to keep blood sugars stable, but that would allow even more freedom to eat as many carbs as she wanted, resulting in even more insulin being injected.
The problem with treating any diabetic (even T1's) this way is that the more carbs they feel free to eat, allowing the pump to just cover them, the more likely the possibility of them starting to become insulin resistant, which means the pump will just give them more insulin to keep blood sugar down.
If the likelihood of developing dementia is related to insulin levels, it doesn't surprise me one bit if T1s are also more likely to get dementia.
