As part of our project to develop methods for multi-site studies, we unexpectedly received data collected from a child with Bilateral Perisylvian Syndrome (BPS). This was unexpected for a dataset involving children with dyslexia because BPS often presents with epilepsy, mental retardation, and motor impairments. This case did not exhibit these more severe phenotypes and instead had relatively specific deficits on measures of phonological processing tasks compared to higher level language and cognitive abilities. This observation is important because it shows that the BPS clinical profile can include relatively mild impairments that includes reading disability. Additional details about this case and BPS have been published in the journal Cortex.
