Study Summary

This study will investigate whether transcranial direct current stimulation (tDCS) enhances the effects of computerized cognitive training in older adults with recurrent depression (2 or more lifetime episodes; either current or within past 3 years).

Primary Outcome

MRI scans will be performed at baseline and after completion of the intervention. MRI will measure Cognitive Control Network function, operationalized as change in n-back functional MRI response in the anterior cingulate cortex (ACC), dorsolateral prefrontal cortex (DLPFC), and the posterior parietal cortex (PPC) regions of interest. The n-back functional MRI response is calculated as the activation difference (beta values) between 2-back and 0-back conditions of the n-back over time (post treat
