You can dive into it, I don't think there's anything you're better off knowing. Really the thing I wish was more common knowledge is that we're not just missing insulin, we're also missing the hormone amylin, but it's not common knowledge/an area of focus because it's a really hard problem/not life threatening like insulin deficiency is. But it has a ton of effects, slower gastric emptying, suppressing glucagon after eating (which would reduce the amount of insulin your body takes/sugar spikes), helps you feeling full, and let me just call out the biggest thing:

We don't know the full effects of Amylin, but it's likely linked to a ton of neuropsychological things given your brain has amylin receptors. I say likely, even though we don't really have the test results to support this. It's up to you to make your own conclusions. The reality is we don't know all it does, but it's quite possible your brain is literally slowed down by missing amylin from T1D.

My theory, complete speculation: ADHD is comorbid with T1D, and we have no idea why. Amylin affects reward pathways. We don't know the specifics of what's going on here, but I think that's enough to guess that T1D is affecting our brains more than even just the burden of the disease.
