Summary

This study tests a gentle brain stimulation method called tDCS in 41 veterans who had a mild traumatic brain injury over a year ago. Participants receive either real or fake stimulation while doing memory exercises. The goal is to see if tDCS can improve thinking skills and daily function, and to find brain markers that predict who benefits most.
