Adhd is actually pretty hard to do this with compared to Autism. Like Newton building hidden networks in his house to avoid interacting with people - yep that’s autistic af. But adhd is a lot more difficult to determine.

In saying that I do think Leo was likely neurodivergent in some way, and adhd does fit. In our own way, a lot of adhders are polymaths because of how we often cycle through interests, slipping in and out of hyperfocus, picking up various skills along the way.

Considering how often people (especially women) are under/misdiagnosed I’d rather not speculate on historical figures… can’t we just celebrate contemporaries? ADHD is debilitating but some of us manage to do amazing things in spite of it.
