New study tests brain games and nerve zap to clear long COVID fog and get people back to work

This study compares two cognitive rehab programs for adults with long COVID who have mild to moderate brain fog. Both programs include computer games, in-lab training, and a mild nerve stimulation device worn on the ear. One group focuses on processing speed and work-related tasks, the other on relaxation and healthy habits. Researchers will measure thinking speed, daily function, and whether participants can return to work. The study is small (30 people) and results are expected to show if this approach is worth testing in larger trials.
