Transcranial direct current stimulation (tDCS) is a noninvasive neurophysiological technique related to excitatory and inhibitory modulation of brain networks. Children and adolescents with Cerebral Palsy (CP) are more likely to have learning difficulties on math and studies on ways of intervention on subjects are scarce, the focus of this study is to investigate the effects of unilateral anodic right unpaired posterior parietal cortex PPC associated with cognitive training (number race) about an improvement in numerical cognition in children and adolescents with CP and difficulties in learning mathematics. Ten children and adolescents with hemiplegic and diplegic CPs, aged 8 to 17 years (mean = 11.40, dp = 2.83) participated in this study. Participants were invited to participate in the two phases of the study: phase 1 assessment and recruitment and phase 2 active stimulation (tDCS). In Phase 1, the participants underwent a neuropsychological and psychopedagogical evaluation that lasted three nonconsecutive days. Phase 2 lasted seven days, two days to collect measures of cortical excitability obtained by extracting the motor threshold (pre and post tDCS) and five consecutive days for an application of tDCS anodic on PPC. In the results we observed that the cortical excitability pattern increased significantly from the pre-phase to a post-intervention, demonstrating that it is a technique for effective modulation of cortical physiological state. The following outcomes were found: numerical cognition (total Zareki-R battery score) and measures of attention and executive function (FDT). Overall numerical cognition presented clinically relevant improvement. These findings point to the potential of tDCS associated with cognitive training without treatment of impairments in numerical cognition in individuals with CP and difficulties in learning mathematics.
