I worked with brain injured children and children with autism. It is real and debilitating. I helped children though horse therapy. I saw autistic children on a spectrum of physical and mental disabilities. You would not wish autism on anyone and especially the burden of genius. A few people may have high IQ and also have Asperger syndrome, autism/ brain damage. But many people are geniuses without brain damage.

Autistic people suffer numerous physical problems usually associated with their digestive system. Around 75% are below 70 IQ....

Genius abilities carry a burden as well, with gifted people they usually don't have room for social skills. That is a generalization though, I have never worked with a genius, all I know is what I have read, they are a pain in the neck....hahaha <3
