Curate, connect, and discover
Autism is developing entire species with full evolution paths, hierarchies, and unique customs for the world from just a single thought that you then expand on.
(I also spent approx 5 hours worldbuilding the other day)
ADHD is developing the plot for an entire book while zoned out and daydreaming and then getting so immersed in it that you spend the next week developing characters, their traits, places, development, twists and turns and just hoping the creativity holds up and you'll get to finish it.
