A new French study of 13 high-functioning adults with autism spectrum disorder found that inhaling oxytocin made the subjects more social and open to relating to others.

According to the London Times, Elissar Andari, of the Institut des Sciences Cognitives, a French government centre for neuroscience research presented the findings at a conference.

The article doesn't say how long improvements lasted; in the first study of oxytocin for autism, Eric Hollander and Jennifer Bartz of the Seaver Centers for Autism found they lasted up to two weeks.
