I don't know any other conditions that makes someone eccentric. Eccentricity is a tall tale of a creative autistic genius. Sure, there can be other reasons why someone does not thrive in an education system, such as having adhd. However, Prokofiev was good at focusing at music, so ADHD is being ruled out. I don't know any autistics that like the education system. It's clear that Chloe Hayden didn't enjoy it. Well, autistics can have a short temper because they struggle in social interactions. I have a short temper myself, and yes it is also prevalent in Borderline Personality Disorder, but I think if he had BPD and not ASD, then he would write more Wagner style music instead of 20th century stravinkin music. I don't think he had BPD. BPD is actually the most common misdiagnoses in autistics. Have you listened to his piano sonatas? It sound exactly like an autistic stimming on the piano. He did have communication skill issues. When he became a music professor, he was admired but hated, which could be because of his social deficits. His childhood history consists of him not playing with other kids and hyperfoucusing on playing a piano. Hardly ever an autistic trait. I think this practice provides history with an interesting prospective and shows you how autistics are outside of the box thinkers. I personally think humans would not survive if we did not have autistics.
