New research shows that adults with traumatic brain injury can improve both brain structure and thinking skills by doing computerized cognitive games. Researchers divided 17 adults into two groups. One group used a computer program with training games and the other group did not. The games asked people to remember syllable patterns, tell apart different sounds, and recall details from a short story. Participants did the training in many sessions over several weeks.
Brain scans showed changes in nerve-fiber pathways, a sign of neuroplasticity — the brain's ability to change. People who did the games scored better on tests of processing speed, attention, and working memory, suggesting some repair of brain connections.
