Autism is a disorder that one in 100 people have. It affects people in different ways, but causes difficulties in social interaction and communication. So far, there is no effective treatment for the social problems that autism causes. Researchers at Yale have studied the brain chemical oxytocin as a possible treatment for the social problems caused by autism because it plays an important role in bonding and trust.  Results have been mixed, though: one recent study found no significant benefit for young people given the chemical over several days. But Pelphrey said oxytocin might help the brain learn from social interactions; it would work best when used with therapies that encourage people with autism to interact more socially, he said.
