Not to freak you out- I just saw a study that looked at children with delayed speech that were labeled "Autistic". When the MD ran an EEG (a test that looks at the spike and wave of your brain) They realized some of these kids were having mini seaizures that could not be detected by the human eye- not the big tonic-clonic ones that everyone thinks about when they hear epilepsy or seizure disorder, but tiny seaizures you would never know they were having. Once the kids were started on an AED, their speech developed normally as did other social/developmental functions. See a pediatric neurologist at children's, there are many wonderful doctors there. Best of luck. Email back if you need any further information.
