Introducción. Existe un acuerdo importante en la consideración del trastorno por déficit de atención/hiperactividad (TDAH) como una patología del neurodesarrollo caracterizada por déficit dopaminérgicos y noradrenérgicos de los circuitos frontoestriados que afectan al funcionamiento ejecutivo en el rendimiento cognitivo. Objetivo. Evaluar la existencia de déficit en memoria en niños con TDAH asociados a un deficiente rendimiento ejecutivo. Sujetos y métodos. Administramos a 14 niños diagnosticados de TDAH tipo combinado y a 14 controles equiparados en cociente intelectual, edad y nivel de escolarización, un protocolo de evaluación neuropsicológica destinado a evaluar funciones ejecutivas y habilidades de memoria, mediante las pruebas Auditory Verbal Learning Test, test de memoria de historias test de memoria y aprendizaje (TOMAL),figura compleja de Rey, recuerdo selectivo visual (TOMAL), torre de Hanoi, test de memoria de frases (Siegel y Ryan), test de dígitos (escala de inteligencia para niños de Wechsler revisada) y test de tapping visual (escala de memoria de Wechsler III).Resultados. Se encontró que los niños con TDAH presentan déficit en el aprendizaje y en el recuerdo libre del material verbal descontextualizado y contextualizado, en la memoria de trabajo y en la memoria procedimental. Por el contrario, no se encontraron diferencias significativas entre los grupos en las pruebas de memoria de naturaleza visuoespacial y visuoperceptiva.Conclusiones. Los resultados obtenidos se analizan en términos de dificultades en las estrategias de codificación, almacenamiento y búsqueda de la información previamente almacenada en el grupo con TDAH, al menos para la información de naturaleza verbal. Estas dificultades están asociadas a déficit en el funcionamiento ejecutivo
Introduction. There is an important agreement on the consideration of attention deficit hyperactivity disorder(ADHD) as a condition characterized by neurodevelopmental dysfunction of fronto-striatal dopaminergic and noradrenergic circuits with resultant executive deficits in cognitive functioning. Aim. To assess the existence of memory deficits in children with ADHD associated with a poor performance executive. Subjects and methods. We assess 14 children diagnosed with ADHD combined type and 14 controls matched on intellectual coefficient, age and level of schooling, in a neuropsychological evaluation protocol designed to assess executive functions and memory skills using Auditory Verbal Learning Test, Memoryfor Stories Test Test of Memory and Learning (TOMAL), Complex Figure Text, Visual Selective Reminding Test (TOMAL), Tower of Hanoi, Memory Phrases Test (Siegel and Ryan), Digit Span (Wechsler Intelligence Scale for Children-Revised) and Tapping Test (Wechsler Memory Scale III). Results. The ADHD group showed deficits in the learning and free recall of verbal material, in procedural and working memory. No group differences were observed in the visual memory tasks. Conclusions. The results are analyzed in terms of difficulty in coding strategies, storage and search of information previously stored in the group with ADHD, at least for the kind of verbal information. These difficulties are associated with deficits in executivefunctioning
