I read through the thread because I did not want to duplicate any answers.
I would have liked to have said Benedict Cumberbatch's Sherlock, but the autistic spectrum never pops up. Although when referred to as a psychopath his response was "I'm not a psychopath, I'm a high-functioning sociopath. Do your research."
Although I found this article that says psychopaths are divided into two groups, primary and secondary. Secondary is a "fancy way of saying sociopath."
This neuroscientist lets us know if Sherlock is actually a sociopath
But is he on the autistic spectrum? Maybe? I use to wonder. There seems to be some overlap of symptoms, but just because I am on the spectrum, that does not mean I'm an expert, and it doesn't mean script writers are experts. They can be loose and slippery when it comes to articulating a diagnosed condition. This part belongs under another thread, but I do have a crush on Molly Hooper, and to bleed a bit into another thread, I never considered dating a fictional crush. The talk about Sherlock has prodded me to watch it again, from the beginning.
I feel comfortable with the following -
Sam from Atypical
Abed Nadir from Community
Max Braverman from Parenthood
Tina Beltcher from Bob's Burger
Woo Young-woo from Extraordinary Attorney Woo
Kim Jeong-hun from episode 3 of Extraordinary Attorney Woo - I had to look this character up. He was autistic and accused of killing his brother.
Forrest Gump from Forest Gump
Amelie Poulain from Amelie
Oskar Schell from Extremely Loud & Incredibly Close
Maurice Moss from The IT Crowd
Raymond Babbitt from Rain Man
Abby Sciuto from NCIS - maybe? I often think so
Adam Raki from Adam
Jerry Espenson from Boston Legal
Sonya Cross from The Bridge - How would Alex feel if I over looked this one?
and others have said -
Temperance Brennan from Bones
Sheldon Cooper from The Big Bang Theory
Amy Farrah-Fowler from The Big Bang Theory
Boo Radley from To Kill a Mockingbird
I do think the Benedict Cumberbatch's Sherlock as misdiagnosed himself. I think both he and Mincroft
Now I'm researching... Don't follow the link if you enjoy exploring your own "memory palace." My "memory palace" has termites.
