Larry Mantle talks with UC San Diego Neurosciences Professor Eric Courchesne, the author of a revealing new study on autism. The study finds that many autistic children show unusual brain growth patterns in infancy. The findings suggest that autism is a disease present in individuals before birth. The findings also suggest that children may benefit from autism treatments much earlier than previously thought. Larry Mantle also talks with Portia Iversen, parent of child with autism and co-founder of "Cure Autism Now," a non-profit organization in Los Angeles that funds research on autism.
