Why do I feel like this will actually be used for OVER-diagnoses and OVER-medication like what always seems to happen? From the post: >>Groundbreaking new autism research suggests that already-rising diagnoses could jump more significantly in the coming years if a new framework for understanding the condition comes into play. The latest research out of Princeton University and the Simons Foundation uncovered four unique subtypes of autism, each with its own genetic 'fingerprint' - finally explaining why some children show signs early while others aren't diagnosed until school age. Researchers have uncovered the missing link in autism's origins by connecting clusters of behavioral traits to specific genetic differences, discovering that each autism subtype has remarkably distinct DNA profiles.
