This document discusses strategies and technologies for recovering cognitive functions lost due to traumatic brain injury (TBI). It notes that TBI survivors can experience decades of debilitation from attention deficits, memory impairments, and executive dysfunction. While severity of injury correlates somewhat to impairment, the link is weak. Even one year post-injury, many TBI patients still have unmet cognitive needs. The document advocates strategies that both compensate for losses and recover functions, using knowledge, technology, systems, processes, retraining, stem cells, and pharmacological and learning enhancements. Computerized cognitive training alone is not a complete solution but can provide effective tools when used by clinicians. Challenges include ensuring training gains transfer to real life and addressing
