These results highlight the usefulness of auditory event-related potentials to directly evaluate, and characterize speech and language processes in Rett syndrome, and other developmental disorders that limit speech.
The researchers hope that one day these kinds of event-related-potential signatures will be used to characterize outcomes of clinical trials, such that the effectiveness of a treatment can be evaluated by its ability to restore a typical signature.
“Our study is the first to examine spoken word comprehension in Rett syndrome,” the researchers wrote. “These results provide a strong rationale for using event-related-potentials during passive listening to spoken words as a marker of auditory content processing in participants with Rett syndrome or other developmental disabilities for whom few optimized standardized behavioral assessments of language exist.”
