Researchers continue to try to figure out what causes autism. A new study now shows babies' brains may show early signs of autism during infancy. Long before any behavioral symptoms are noticed .
British researchers monitored the brain activity of six to ten month old babies, as they looked at pictures of faces, looking at and away from them. The babies who eventually were diagnosed with autism were more likely to have different brain responses to these social interactions than those who were not autistic.
Although this method was not 100 percent accurate, researchers believe these findings may be a first step in predicting autism as young as six months old.
