Brain injury, or damage to the brain and/or surrounding structures, is listed by the CDC as the leading cause of disability and death in the United States. This kind of injury can result in symptoms that physical, cognitive, and behavioral functioning in those affected. Despite this, current literature reflects a significant deficiency in the understanding and management of behavioral symptoms, that present after the injury, in most neurorehabilitative treatments. This study aimed to investigate whether sustaining a brain injury can effect an individual’s demand intensity for alcohol, if their demand was inelastic, and their probability for misuse of alcohol. To evaluate this, 50 participants (25 control, 25 injured) completed an alcohol use disorders identification test (AUDIT) and an alcohol purchase task (APT). Demand results were then analyzed using a modified exponential equation to measure the demand intensity, Omax, Pmax, and breakpoints. In addition to this, a statistical analysis was done using an unpaired t-test and a chi-square test on both the demand and AUDIT data collected. We concluded that the individuals who had sustained an injured had a higher intensity of demand that was inelastic to the changes in prices. They also demonstrated a higher Omax, Pmax, and breakpoint when compared to the control participants.
