Abstract
INTRODUCTION: Developmental dyscalculia (DD) deals with impaired mathematical performance and affects the educational and day-to-day activities of children. There is evidence that transcranial direct current stimulation (tDCS) applied to the posterior parietal cortex facilitates the hypoactive neuronal structure and improves mathematical performance in individuals with DD. OBJECTIVE: The objective of this study is to investigate whether tDCS adjuvant with conventional numeracy training (CNT) would enhance the mathematical abilities of school-going children affected with DD. MATERIALS AND METHODS: Thirteen school-going children affected with DD received tDCS and CNT three sessions per week for up to 2 consecutive weeks. Left anodal and right cathodal stimulation at P3/P4 region with 2mA intensity combined with CNT for 30 minutes in a day was given. Learning disability diagnostic inventory (LDDI) was used as an outcome measure and collected at baseline and the end of the 2-week intervention. RESULTS: There was a significant improvement in the mathematical performance of school-going children. The results show statistically as well as a clinically significant improvement after the 2 weeks of intervention. CONCLUSIONS: tDCS combined with CNT is effective for improving the mathematical abilities of school-going children affected with DD. The findings of this study provide a new perspective for the rehabilitation of school-going DD children.

ABSTRACT | INTRODUCTION: Developmental dyscalculia (DD) deals with impaired mathematical performance and affects children's educational and day-to-day activities
O processamento de números, as tarefas numéricas e os cálculos são processados por uma combinação do lobo parietal, córtex pré-frontal, cerebelo, via visual dorsal e ventral e áreas subcorticais
No presente estudo de grupo único, todos os participantes receberam tDCSat anódico esquerdo (P3) e catódico direito (P4) região parieto-temporal combinada com treinamento em numeramento convencional. 15 crianças com idades entre 8 e 17 anos foram avaliadas para elegibilidade para o estudo
Summary
Estimulação transcraniana por corrente contínua para melhorar o desempenho matemático em crianças discalculia de desenvolvimento em idade escolar: um único grupo pré-teste-pós-teste, estudo quase experimental. O uso da estimulação cerebral não invasiva oferece a facilitação de diferentes regiões cerebrais, por induzir a excitabilidade, podendo resultar em ativação e melhora de funções.[8] Aplicações de estimulação transcraniana por corrente contínua (ETCC) para fins de reabilitação em DD são relatadas e documentadas com melhora da proficiência numérica após estimulação anódica no córtex parietal posterior esquerdo em adultos com discalculia.[9,10] Até o momento, nenhum estudo foi realizado ainda para estabelecer a eficácia da tDCS na melhoria das habilidades matemáticas de crianças em idade escolar afetadas com DD.
