Language disorders in children are one of the most frequent causes of difficulties in communication, social interaction, learning and academic achievement. It has been estimated that over 5% of children present with some kind of language disorder. This volume illustrates the state of the art in neurogenic language disorders in children. The most recent findings about acquired epileptiform aphasias (from Landau-Kleffner syndrome to autistic regression) are presented and discussed. Language disorders in children with early brain lesions are reviewed in relation to the side of the lesion and their epileptic correlates (e.g., paroxysmal abnormalities during NREM sleep). New clinical reports are presented and a large discussion is held on language disorders due to malformation or tumor lesions localized to the Posterior Fossa. The last part of the volume reviews the state of the art on some of the most debated clinical neurolinguistic pictures of developmental age such as crossed aphasia in children, the modality and types of aphasia recovery in children and persistent acquired childhood aphasia.
