It's safe to say that you've probably heard of autism, the range of developmental disorders that makes life a challenge for millions of people across the world. Awareness of its existence and methods for helping those who suffer from it have made great strides forward over the past decade, with a much greater understanding being apparent in the world at large. Idiots like Michael Savage notwithstanding, of course.
Autism usually manifests as delayed language development, with the exception of the Asperger variant. Autistic people often have trouble communicating, great difficulty in social settings, intractability with non-essential routines, and can be narrowly focused on highly specific interests.
