A new study suggests that the increase in the number of children being diagnosed with autism is due, in least in part, to the way that diagnosis is defined.
The number of U.S. children enrolled in special education programs due to an autism diagnosis more than tripled between 2000 and 2010.
A new study from Penn State University says that may be because educators traded one diagnosis for another.
Dr. Susan Hyman, an autism expert at UR Medicine, says this is not a matter of semantics. The right diagnosis means a child will get the best treatment and services.
