The main objective of this study is to evaluate the effects of tRNS while undergoing computerized cognitive rehabilitation therapy to conclude if this combination of therapies would be effective for the cognitive rehabilitation of patients with acquired brain damage, such as traumatic brain injury. We want to study the therapeutic potential of tRNS to enhance the therapeutic outcome of cognitive training, studying its global effect over the rehabilitation of attention, memory and executive functions, compared to sham tRNS.
