Research shows abnormal function of the pre-frontal cortex in Attention Deficit Hyperactivity Disorder (ADHD). This cortex is involved in the control of executive functions related to planning and execution of goal-oriented strategies, working memory, inhibitions, cognitive flexibility, and selective attention. Selective attention involves focus on the target stimulus, ignoring competing distractions. The Stroop Test (Stroop, 1935) is usually used to evaluate selective attention. This study investigated whether children with ADHD could exhibit modified performance in the Stroop Test. Using a computerized version of this test (Capovilla, Montiel, Macedo, & Charin, 2005), the study compared the reaction times (RTs) of 62 Brazilian children, between 8 and 12 years of age, 31 of whom were diagnosed with ADHD and sent to psychiatric clinics, and 31 without ADHD studying in regular schools. All children with ADHD satisfied the criteria of the DSM-IV-TR and were evaluated with the Conners Abbreviated Questionnaire (Goyette, Conners, & Ulrich, 1978), completed by parents and teachers. The results revealed that children with ADHD exhibit greater interference in RT than children without ADHD. This corroborated the hypothesis that children with ADHD exhibit a deficit in selective attention, consisting in augmented RTs, as measured by the Computerized Stroop Test.

Executive functions (EF) can be promoted by classroom interventions. Our study investigated whether (a) an intervention conducted by teachers improves EF in children; (b) there are effects on behaviour and academic achievement; and (c) there are stable benefits in a one-year follow-up. Fifty-eight first-graders, divided into experimental (EG = 28) and control (CG = 30) groups, were assessed in EF, reading and arithmetic tests. Parents and teachers answered EF and behaviour functional scales. The intervention was conducted by teachers in the classroom context. EG children showed greater gains in EF and outperformed controls on reading and arithmetic measures. The EG maintained better performance in the one-year follow-up and showed transfer effect for behaviour measures. The EF intervention may be a useful tool for promoting improved adjustment and academic achievement.

Resumo O presente estudo objetivou apresentar um panorama nacional e internacional atual dos estudos sobre o vírus Zika (ZIKV) e, ancorado no avanço deste conhecimento, refletir sobre planos de ação voltados para as crianças, famílias e equipes de saúde envolvidas. Neste sentido, o estudo propôs a implementação de sistemas de seguimento para conhecer, descrever e caracterizar aspectos que devem estar relacionados à exposição pré-natal ao ZIKV, divididos em três eixos de atuação: 1. Avaliação diagnóstica e etiológica e rastreamento de problemas de desenvolvimento nas crianças incluídas como casos confirmados ou suspeitos. 2. Investigação do impacto emocional, da qualidade de vida, das estratégias de enfrentamento e da rede de apoio às famílias das crianças incluídas. 3. Capacitação de equipes multiprofissionais para avaliar e elaborar programas de intervenção ao longo do desenvolvimento das crianças, principalmente nos três primeiros anos de vida. Como conclusão, o presente trabalho ressalta que o sistema de assistência à saúde encontra-se diante de grandes desafios: entender o real significado de um potencial novo teratógeno; desvendar os mecanismos patogênicos do ZIKV, principalmente para o enfrentamento preventivo, e reconhecer o amplo espectro de manifestações clínicas para a elaboração de programas de intervenção.

This systematic review aimed to characterize empirical studies on neuropsychological interventions to stimulate executive functions in children with typical development. Searches were conducted according to the PRISMA method. Nineteen (19) studies on the analysis to evaluate the effectiveness of intervention programs in pre-school and school children were obtained. There was a predominance of studies that used computerized cognitive training, most of them involving the stimulation of working memory. Others used pen and paper forms, or hybrid tasks, and some programs used a school curriculum approach aiming to improve self-regulation. Results provide preliminary evidence on the effectiveness of such on the executive performance in children with typical development. Each executive component, as well as each type of intervention has its peculiarities. Computerized trainings and pen and paper tasks tend to improve the targeted executive functions, but transfer effects are still inconsistent. Regarding the effects of programs using school curriculum approach, they seem to be more generalizable, with functionality gains accomplishing mainly socio-emotional regulation. Multimodal approaches may be even more effective. Follow-up studies should be targeted in order to track the maintenance of direct and transfer effects regarding mainly cognitive and social development associated to school achievement.

Despite the crucial role played by the executive functions (EF) to cognitive, emotional, and social development of children before and during school years, little attention has been given to construct and analyze the efficacy of programs that intend to develop them. The program of neuropsychological stimulation of cognition in students: emphasis on EF, or PENcE (an acronym from its original name in Portuguese, Programa de Estimulação Neuropsicológica da Cognição em Escolares: ênfase nas Funções Executivas), is an early and preventive intervention program for school-aged children, and implemented at school three times a week for 5 months. The PENcE was structured in four modules, each focusing on a different executive component: organization and planning, inhibitory control, working memory, and cognitive flexibility. The objectives of this study were to verify the effectiveness of the PENcE among elementary school children and to investigate whether there are transfer effects to other executive, cognitive, and academic abilities. The sample consisted of 113 children attending 3rd or 4th grade at two public elementary schools. Eight classes participated in the study, divided into two groups: an experimental group (EG) (four classes; n = 64), which received the intervention, and a control group (CG) (four classes; n = 49), which continued their regular school activities. The EF and academic skills of both participant groups were evaluated before and after the intervention. The EG showed significantly greater improvements in inhibitory control, working memory, and abstract planning relative to the CG, with a small to medium effect size. There were transfer effects to other cognitive and academic abilities. These findings suggest the PENcE may be a useful method of improving EF and could benefit both school-aged children and education professionals.
