Absence seizures may be difficult to diagnose in children with ADS, and are rarely reported. Two case presentations illustrate that stereotypic and inattentive behavior considered to be part of ASD may in fact be absence seizures. An EEG should be routine in all children diagnosed with ASD.
Autism Spectrum Disorders (ASD's) have three types of clinical symptoms (deficits in social communication, social interaction and restricted repetitive patterns of behavior or activity).
"Absence seizures" (previously called "petit mal" seizures) are a type of brief (few seconds) generalized seizure that causes short periods of lapses in awareness (sometimes with staring - "blanking out" and frequently mistaken in children for daydreaming).
