“…Changes in cerebral network connectivity, though different from those in our study, have recently been demonstrated. 40 If our results are maintained even after comparison with other language-impaired patients without evident structural brain damage, the influence of epilepsy can be confirmed.…”

“…These regions are implicated in phonological processing of information, an area of difficulty strongly implicated in RDs. Studies have found connectivity differences in the regions of the prefrontal network and inferior parietal regions, with increased connectivity present for children and adolescents with dyslexia and decreased connectivity in the dorsolateral prefrontal and posterior parietal areas [28]. It also has been demonstrated that poor beginning readers show less lateralization compared with good beginning readers, particularly in the frontal network [29].…”

The relationship of attention-deficit/hyperactivity disorder (ADHD) to learning disorders was reviewed and included reading disability, mathematics learning disability, and nonverbal learning disability. Genetic, neuroimaging, and neuropsychological functioning were examined for each disorder, along with a discussion of any existing literature when ADHD co-occurred with the disorder. All the disorders were found to frequently co-occur with ADHD. A review of the underlying neuroanatomic and neurofunctional data found specific structures that frequently co-occur in these disorders with others that are specific to the individual diagnosis. Aberrations in structure and/or function were found for the caudate, corpus callosum, and cerebellum, making these structures sensitive for the disorder but not specific. Suggestions for future research, particularly in relation to intervention, are provided.

“…Se ha constatado que en un 32,2%, específicamente en sujetos manidiestros, se objetiva una anormal lateralización cortical del lenguaje con un patrón de representación bilateral 30 . Ello podría explicar y conllevar un déficit en el procesamiento fonológico, dependiente de un circuito neural frontoparietal izquierdo, en niños con dislexia del desarrollo 31 . Finalmente, el normal neurodesarrollo de las habilidades lingüísticas depende de una correcta neuromaduración de la sustancia blanca y, específicamente, en las áreas lingüísticas perisilvianas.…”

ResumenEl lenguaje es uno de nuestros dominios cognitivos más preciados. El estudio de dicha función neuropsicológica en las tres últimas décadas mediante técnicas de neuroimagen, y específicamente a través de la resonancia magnética funcional (RMf), ha proporcionado nuevos datos acerca del procesamiento cerebral del lenguaje y ha ampliado los clási-cos ya conocidos. Básicamente se pueden definir cinco ámbitos de interés que se detallan en el presente artículo. El primero se centra en delimitar las áreas cerebrales que definen el circuito neural del lenguaje. El segundo intenta definir con mayor detalle la implicación de las diferentes áreas cerebrales en los distintos componentes lingüísticos, especialmente en el fonológico, el sintáctico y el semántico. El tercero se circunscribe al estudio de la reorganización funcional del lenguaje tras un daño cerebral. El cuarto se centra en la posibilidad del estudio no invasivo de la lateralización cerebral del lenguaje en la planificación prequirúrgica. Finalmente, el estudio de la etiopatogenia y la anormal actividad funcional lingüística de los trastornos del desarrollo del lenguaje oral y escrito para comprender su probable anormalidad neurobiológica. No obstante, se asume que la RMf presenta limitaciones en el estudio del procesamiento cerebral del lenguaje y precisa de la información obtenida mediante otras técnicas de neuroimagen y neurofisiológicas.
