Language dysfunction in epileptic conditions

Epilepsy may disrupt brain functions necessary for language development by its associated intellectual disabilities or directly as a consequence of the seizure disorder. Additionally, in recent years, there has been increasing recognition of the association of epileptiform electroencephalogram (EEG) abnormalities with language disorders and autism spectrum disorders. Any process that impairs language function has long-term consequences for academic, social, and occupational adjustments in children and adolescents with epilepsy. Furthermore, impairments in specific language abilities can impact memory and learning abilities. This article reviews interictal language function in children and adults with epilepsy; epilepsy surgery and language outcome; and language disorders associated with abnormal EEGs. The relationship between epilepsy and language function is complicated as the neuroanatomic circuits common to both overlap. We demonstrate how magnetoencephalography (MEG) offers the ability to analyze the relationship of language, EEG abnormalities, and epilepsy.

      Research is needed to examine extended language use in natural situations in the pediatric epilepsy population to further our understanding of the contribution of language to social deficits. We know that language is important for the development of social skills (Wheless et al., 2002). Research examining language use in social contexts could help establish whether social skills deficits in children and adolescents with epilepsy are associated with language deficits or seizure activity to better inform treatment and prognosis.

      Autism spectrum disorders are characterized by atypical communication, deficits in social reciprocity, and stereotyped or narrow ranges of behaviors or activities. Some epilepsy syndromes, such as Landau–Kleffner syndrome, include irregular communication styles or atypical social pragmatic language, similar to what is present in autism [82]. Ultimately, the overlap may be physiologic in nature.
