Brain Injury Research Group (BIRG)

Our mission is to conduct basic and applied research into the cognition and language of healthy aging adults and adults who sustained a brain injury due to stroke, traumatic brain injury, or progressive neurodegenerative disease, such as Alzheimer’s disease or other dementias. BIRG’s goals include (a) advancing our knowledge about the effect of aging and brain injury on cognition and language, and (b) using this knowledge to improve assessments and rehabilitation techniques for individuals with brain injury.


BIRG was established in February 2018 among faculty from the University of Arkansas at Little Rock and the University of Arkansas for Medical Sciences to coordinate research into acquired neurogenic communication disorders. The faculty have expertise in the assessment and intervention of cognition and language for the following disorders:

  • Aphasia
  • Dementia
  • Concussion
  • Traumatic Brain injury

Current Research

Effects of Mild Traumatic Brain Injury on Cognition and Language in Adults: The project investigates cognitive and language changes from one or more mild traumatic brain injuries (mTBI), including sub-concussions and concussions, with the long-term goal of improving the accuracy and scope of mTBI assessment.

  • Status: Ongoing.
  • Adults participants with and without a head injury are needed.

Neural Correlates of Word Learning: The project investigates patterns of brain activity and cognitive abilities associated with word learning in healthy aging adults. The long-term goal is to elucidate the effects of aging on word learning compared to word learning abilities in adults with aphasia or progressive neurodegenerative disease.

  • Status: Phase 1 Complete.
  • We are not currently recruiting.

Longitudinal Changes Associated with Healthy Aging, Mild Cognitive Impairments, and Dementia: The project investigates the cognitive and language changes in healthy aging adults and adults with a Mild Cognitive Impairment (MCI) or dementia across a three-year period. The study includes measures of attention; memory; executive function; and language production and comprehension. The goal is to improve cognitive and language assessments to detect and treat cognitive impairment earlier.

  • Status: Planning
