Brain zapping + brain games may sharpen focus after concussion

This study tested a new way to help active-duty service members who had a mild traumatic brain injury (concussion) at least 6 months ago and still struggle with attention, concentration, or memory. Researchers combined a gentle, noninvasive brain stimulation technique called tDCS with computer-based cognitive training. They compared real stimulation to a sham (fake) version to see if the combo could improve thinking skills and brain activity. The goal was to find a safe, drug-free method to ease lingering cognitive symptoms.
