Interesting but not quite the "break through" claimed in the article. Its been pretty common knowledge since the seventies (at least among researchers in the field) that autism and related disorders are biologically caused by genetics and brain function and structure abnormalities. They just can't isolate specific genes as its too complex or determine the exact cause of these causers. Also it can be said that diagnosed cases have "skyrocketed" yet the concept of an actual rise or "epidemic" is still hotly debated.
