This is an informative TED talk on the latest understanding of autism from a scientific perspective. I tend to agree with Dr. Chung that autism is likely a catch-all phrase for what we may someday discover to be various neurological conditions.
I'm halfway through Andrew Solomon's book, Far from The Tree, an often gut-wrenching and yet uplifting look at "families coping with deafness, dwarfism, Down syndrome, autism, schizophrenia, multiple severe disabilities, with children who are prodigies, who are conceived in rape, who become criminals, who are transgender." I had hoped to write my thoughts on the book here, and maybe I still will. In the meantime, Solomon's recent TED Talk, Love, no matter what, provides a moving, fascinating overview of the territory covered in the book. Consider taking 20 minutes to watch it; it had a profound effect on me.
