Some might find this interesting, but I've heard theories about people who's brains have similar traits to the medical 'labels' of things like schizophrenia, ADHD, Autism etc. In that if they were born into tribes and the elders noticed those traits in you, they'd take you to be trained as a Shaman as that is something these people excel in...I find it very interesting as these types can also naturally be rebellious to 'authoritive figures' and 'society'. As if they also have a conscious awareness early on that there is more to life. I think people with these certain aspects have unique gifts which are obviously shunned on purpose!
