Thank you for sharing that video. I watched it, and I am definitely ADHD. Although there are times when some of the autism characteristics do resonate.
For example, there’s one time when I had a a teacher explaining matrixes and I raised my hand and asked him why we are learning this (which caused considerable snickering on class, and obvious embarrassment for the teacher).
I generally do need to understand why we’re learning something in order to have enough interest to focus on it.
However I don’t think that’s autism, as I feel that it is difficult for anybody to learn something if they don’t even understand how it is to be used.
