Rock Lee definatley has Autism from what he displays socially. Also Izumo has some explicit OCD and Kotetsu has ADHD.
i can see rock lee avoiding eye contact and not interacting with others in the academy and sometimes with his team as well. lee stimming by running laps and doing exercises.
izumo does not like germs at all and needs everything to be in its place. he makes sure all of his missions, even the simple ones such as gatekeeping, goes perfectly and checks on everything all the time.
kotetsu has difficulty with filling his mission reports and is very fidgety when he’s gatekeeping, which is why he prefers doing errands from one end of the village to the other instead of staying in that one place.
