My 10 year old has very obvious ADHD. But she taught herself to read in preschool by following along with audiobooks, and she can focus for hours on things like computer games. Even the computer coding course that she did independently at home, she would stay on task. But she has a big problem staying on task with academic work, esp. if it involves writing, and has a lot of problems with distractability, except for certain tasks like reading a book she really likes. Or doing arts/crafts projects. She stays on task for things that she really enjoys but has a really hard time with other things.
