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.
Can’t we do both? Leo is the godfather of makers, and is widely known across the world. Contemporaries would be great as well, though.
I like to say I don’t have a pile of unfinished projects and half-abandoned hobbies. I’m just working in the style of the great Leonardo.
Tbh I dont think that it is very feasible to decontruct what goes on in someones’ head like that. Modern ADHD testing is as comprehensive as it is because a lot of things can mimic it to varying degrees. eg. sleep deprivation, autism, bipolar, nutrient deficiencies, stress etc. There isnt really a good way to rule those alternatives out (which is what differential diagnosis does) I dont think having artist’s block is convincing enough evidence to diagnose him.
