Autism's Causes: How Close Are We to Solving the Puzzle?

The rise in the number of reported autism cases has caused a surge in research to find the causes. Robert MacNeil speaks with four leading researchers: Dr. Gerald Fischbach of the Simons Foundation, Dr. David Amaral of the MIND Institute, Dr. Martha Herbert of Harvard University and Dr. Craig Newschaffer of Drexel University. It's part three of the Autism Now series of reports.
