A recent study from NYU Steinhardt demonstrates that computerized cognitive games can induce measurable changes in neuroplasticity - the brain's capacity to reorganize itself by forming new neural connections - in adults with chronic traumatic brain injury (TBI). Participants who engaged in a 14-week program of computer games focused on tasks like recalling sequences, distinguishing sounds, and remembering story details exhibited significant improvements in white matter changes, a key indicator of neuroplasticity, which correlated directly with improvements in processing speed, attention, and working memory.

Why it matters

Traumatic brain injury disrupts the intricate network of nerve fibers responsible for essential functions like speech, memory, and problem-solving. However, neuroplasticity allows the brain to compensate for damaged areas by rerouting signals through alternative pathways, which is crucial for functional recovery. This study highlights the remarkable ability of the brain to heal and adapt after injury, particularly through targeted cognitive training.

The details

The study utilized the Brain Fitness Program 2.0, which is designed to challenge and rebuild neural pathways through repetitive practice. Researchers found that the changes in the nerve fibers, such as increased strength and stability, were directly related to the improved cognitive ability in adults with chronic brain injury. The effectiveness of this approach stems from the brain's natural drive to adapt.

  • The study was published in the Journal of Neurotrauma in February 2026.

What they’re saying

“This study reveals that the changes in the nerve fibers, such as increased strength and stability, were related to the improved cognitive ability in adults with a chronic brain injury.”

— Gerald Voelbel, Associate Professor of Cognitive Neuroscience

What’s next

The findings point to several exciting future trends in TBI recovery, including personalized training programs, virtual reality integration, gamification and motivation, remote monitoring and tele-rehabilitation, and combining cognitive training with other therapies.

The takeaway

This study offers a hopeful outlook for individuals recovering from traumatic brain injury, as it demonstrates the remarkable ability of the brain to heal and adapt through targeted cognitive training. As our understanding of neuroplasticity deepens, we can expect even more innovative and effective approaches to brain injury rehabilitation.
