Abstract

At least a third of autistic toddlers regress in language, sociability, play, and often cognition. Many fewer children undergo a similar, unexplained regression after language is fully developed (disintegrative disorder [DD]). Epilepsy or a paroxysmal electroencephalogram (EEG) with/without clinical seizures, including electrical status epilepticus in slow wave sleep (ESES), may be associated, in occasional children, with either selective loss of language (Landau-Kleffner syndrome [LKS]) or with pervasive autistic regression. Fluctuation in language and behavior deficits should raise the suspicion of epilepsy. Review of the literature and of the author's experience suggests that epilepsy probably plays a relatively minor, although non-negligible, pathogenetic role in autistic regression. Multidisciplinary, possibly multi-institutional, longitudinal studies that encompass the regression are needed to sharpen diagnostic criteria to devise more effective therapies.
