“…Studies support the idea that complications in pregnancy or childbirth (perinatal oxygen perfusion problems, toxemia, eclampsia, fetal postmaturity, length of delivery, fetal stress, low birth weight, poor maternal health) may predispose both disorders [26,71,[89][90][91][92][93]. There is evidence for an important association between prematurity and low birth weight with neurodevelopmental delays/disorders including ADHD and/or DCD [94][95][96][97][98][99].…”

“…Deficits in upper-body and upper-limb movement control affect the efficacy and precision in reaching, grasping, and the fine manipulation of objects, thereby constraining the child's interaction with the environment [De Campos et al, 2009]. Upper-limb impairment is frequent (50%-70%) in individuals with cerebral palsy [Elvrum et al, 2012;Uvebrant, 1988]; a condition that is not only more prevalent in children with lower GA [Oskoui et al, 2013], but also, from a symptomatic viewpoint, can be deemed as the far end of the continuum of features that children born PT display [Pearsall-Jones et al, 2010]. Thus, in this realm, upper-limb movements are of particular importance to study.…”

Altered white matter microstructure is commonly found in children born preterm (PT), especially those born at an extremely low gestational age (GA). These children also commonly show disturbed motor function. This study explores the relation between white matter alterations and upper-limb movement segmentation in 41 children born PT (19 girls), and 41 children born at term (18 girls) at 8 years. The PT group was subdivided into extremely PT (E-PT; GA = 25-27 weeks, N = 10), very PT (V-PT; GA = 28-32 weeks, N = 13), and moderately PT (M-PT; GA = 33-35 weeks, N = 18). Arm/hand preference (preferred/non-preferred) was determined through object interactions and the brain hemispheres were designated accordingly. White matter alterations were assessed using diffusion tensor imaging in nine areas, and movement segmentation of the body-parts head, shoulder, elbow, and wrist were registered during a unimanual goal-directed task. Increased movement segmentation was demonstrated consistently on the preferred side in the E-PT group compared with the term born group. Also compared with the term born peers, the E-PT group demonstrated reduced fractional anisotropy (FA) in the cerebral peduncle (targeting the corticospinal tract) in the hemisphere on the non-preferred side and in the splenium of corpus callosum. In contrast, in the anterior internal capsule on the preferred side, the E-PT group had increased FA. Lower FA in the cerebral peduncle, but higher FA in the anterior internal capsule, was associated with increased movement segmentation across body-parts in a contralateral manner. The results suggest that impaired development of sensorimotor tracts in E-PT children could explain a sub-optimal spatiotemporal organization of upper-limb movements.

“…Há também a hipótese de que o TDC esteja relacionado a danos ao cérebro imaturo ou em desenvolvimento, podendo ter mecanismos causais semelhantes à paralisia cerebral [67][68][69] . Diversas regiões cerebrais (giros frontais inferiores bilaterais, giro supramarginal direito, giro angular, córtices insulares, amígdala, putamen e pálido) apresentaram alterações de conectividade funcional semelhantes em crianças com TDAH e/ou TDC, que podem representar possíveis alvos para estudos futuros como potenciais marcadores biológicos para esses transtornos 59 .…”

e 2015, utilizando os descritores "ADHD", "DCD", "comorbidity", "motor skills", "attention", "executive functioning", "neural basis" e suas combinações. A seleção de 72 artigos considerou aqueles mais relevantes de acordo com a abrangência do tema proposto, de forma não sistemática. Resultados. O envolvimento dos gânglios basais e do córtex pré-frontal verificado nos indivíduos com TDAH pode refletir dificuldades de planejamento motor e organização dos movimentos antes do seu início, enquanto que alterações parietais encontradas em crianças com TDC podem estar relacionadas não apenas à preparação, mas principalmente à execução do ato motor. Conclusões. A sobreposição entre o TDAH e TDC pode implicar um substrato neurobiológico comum para ambos os transtornos. Porém, não está claro até o momento quais dificuldades motoras e atencionais são intrínsecas a cada transtorno, devido a não identificação do TDC em muitas amostras com TDAH e vice-versa. Unitermos ABSTRACTObjective. To discuss the neural underpinnings of Attention Deficit Hyperactivity Disorder (ADHD) and Developmental Coordination Disorder (DCD) in children. Although the motor problems occur in 30-50% of children with ADHD, its causes are still unclear. Method. The literature search was performed in PubMed database between the years 2000 and 2015, using the keywords "ADHD", "DCD", "comorbidity", "motor skills", "attention", "executive functioning" "neural basis" and their combinations. The selection of 72 articles considered the most relevant papers according to the scope of the proposed theme, unsystematically. Results. The involvement of the basal ganglia and the prefrontal cortex verified in individuals with ADHD may reflect motor planning difficulties and organization of movements before it begins, while parietal changes in children with DCD may be related not only to the preparation, but mainly the motor act execution. Conclusions. The overlap between ADHD and DCD may involve a common neurobiological substrate for both disorders. However, it is not clear yet which motor and attentional difficulties are intrinsic to each disorder due to failure to identify DCD in many samples with ADHD and vice versa.
