autism

The hunt to find genes that cause autism has been a long slog, one hampered by a lack of technology and families willing to be tested.

But the effort is starting to pay off. On Tuesday, researchers at more than 50 laboratories said they had identified more than 100 genes that are mutated in children with autism, dozens more than were known before.

Scratch one more simple explanation for autism off the list. This time it's the idea that children with autism have low levels of oxytocin, often called the "love hormone" because it can make people more trusting and social.

The symptoms of autism may not be obvious until a child is a toddler, but the disorder itself appears to begin well before birth.

Brain tissue taken from children who died and also happened to have autism revealed patches of disorganization in the cortex, a thin sheet of cells that's critical for learning and memory, researchers report in the New England Journal of Medicine. Tissue samples from children without autism didn't have those characteristic patches.

A University of Kentucky professor has been awarded an $800,000 grant for research into autism therapies. The Herald-Leader says the grant is to develop new display and image processing technologies that allow people with autism disorders to see a virtual image of themselves. The images show the person doing things they need to learn, such as social interactions or sitting still.
