Traumatic brain injury (TBI) impacts 2.5 million people in the U.S. annually. Most people will sustain mild TBI (mTBI). with approximately 13% experiencing chronic cognitive symptoms impacting quality of life. Individuals with mTBI report experiencing sub-clinical deficits in language that include difficulty with starting. maintaining. and following conversations. However. these symptoms are mostly self-reported and elusive using existing clinical tools. Language comprehension demands the efficient construction of a coherent message from a rapid stream of input.
