A maioría dos estudos que se centraron no Transtorno de Déficit de Atención e hiperactividade (en adiante, TDAH) tipo combinado, acentúan que o principal problema se daba nos seus problemas de inhibición de respostas. Mais aquí proponse que no tipo inatento (en diante, DA) é na memoria de traballo, demostrado en diversas probas de atención practicadas nestes suxeitos tales como as probas TEP e IRMF. Condutualmente, máis que estar distraídos, encóntranse aborrecidos, o seu problema está máis na motivación debido a un baixo arousal, do que nun problema de control inhibitorio. En canto a factores neurobiolóxicos, os nenos con TDAH tipo combinado, evidencian problemas no lóbulo frontal, área do estriado. Pola contra no tipo inatento, o problema áchase no lóbulo fronto-parietal, do córtex prefrontal. Polo tanto, trátase de dous transtornos con diferentes bases neurobiolóxicas, cognitivas e condutuais.
Most studies of attention-deficit with hyperactivity disorder (ADHD) have focused and emphasized on the combined type a core in response inhibition. In this work, it is proposed that the core problem in the inattentive type of ADHD, is in working memory.It´s corrobored in laboratory trails as in PET and IMRF trails. Behaviory, children´s with inattentive type of ADHD, rather than being distractible they are bored, their behavior problems being more in a biological under aurousal, than in inhibitory control. For this and other studies be proved that in the combined type of ADHD the primary disturbance be evidenced in the frontal striaal loop, but it is not right for the inattentive type of ADHD (ADD) it is in the cortex frontal parietal loop. Finally, be proposse that these are not two different types of ADHD, they are two different disorders with differnet cognitive and behavioral profiles, and different nderlaying neurobiologies.
