Attention deficit hyperactivity disorder
Conditions
Interventions
There were 10 sessions of transcranial stimulation by active direct current with intensity of 1mA in the active group, which was composed of 16 children
and 10 sessions of transcranial direct current placebo (sham) stimulation in the control group, which was composed of 17 children. In both groups, stimulation was applied to the left dorsolateral pref
the Five Digit Test and the Conners ’Continuous Performance Test (CPT) II.
Paired (simultaneously) with transcranial direct current stimulation, the participants performed 3 activities: reading small
then, simple mathematical calculations, involving the four basic operations (addition, subtraction, multiplication and division), and finally, educational robotics activities, which presented a degree

| Presentation of the expected outcome 1: Transcranial anodic direct current stimulation in the left dorsolateral prefrontal cortex would have superior effects compared to the effects of placebo stimulation, in inhibitory control and attention processes in children and adolescents with attention deficit hyperactivity disorder ; which would be verified through the application of repeated outcome measures in the pre-evaluations, immediately after and three months after the intervention. The level of significance adopted for the statistical tests was 95%.;Presentation of the outcome found 1: Superior effects of anodic transcranial stimulation on the left dorsolateral prefrontal cortex were observed, when compared to the effects of placebo stimulation, on the symptoms of hyperactivity of attention deficit and hyperactivity disorder. The verification of the effects was performed through the application of repeated outcome measures in the pre-evaluations, immediately after and three months after the intervention. The level of significance adopted for the statistical tests was 95%.;Presentation of expected outcome 2: Investigate whether the effects of transcranial direct current stimulation would last for three months after the end of the intervention, by means of an evaluation using repeated measures of outcome, three months after the intervention. The level of significance adopted for the statistical tests was 95%.;Presentation of the outcome found 2: It was observed that the effects of transcranial direct current stimulation lasted for three months after the end of the intervention. This investigation was carried out by means of an evaluation using repeated outcome measures, three months after the intervention. The level of significance adopted for the statistical tests was 95%. | — |
