Language networks in children with Rolandic epilepsy

By March 29, 2017April 3rd, 2018Research News

Recent research published by our team in Epilepsia Open suggests that there is impairment of the language network in children with Rolandic epilepsy. Using functional magnetic resonance imaging (fMRI) we analysed the brains activity at rest. In a comparison with healthy children, children with Rolandic epilepsy had decreased function in parts of the left frontal lobe and parietal lobes (see figure 1). These are regions involved in speech processing, language and reading. This research supports the idea of a delayed language development in children with Rolandic epilepsy and could explain the associated speech, language and reading problems.
