Excessive alcohol use is associated with damage to the structure and function of the brain and impairment of cognition and behavior. Traditional test batteries used to assess cognitive performance in alcoholics are extensive and costly, limiting their use across various clinical and research settings. The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) is a relatively new instrument that attempts to overcome some of these limitations. As yet the indiividual effect of moderate to heavy alcohol consumption on RBANS performance has not been examined.
The primary aim of this study was to explore and quantify differences in performance between controls and drinkers on the RBANS and to examine the influence of age, gender, and alcohol use patterns on test performance.
Our results suggest that the RBANS is able to detect and characterize differences in verbal fluency, visuospatial skills, components of declarative memory, and psychomotor speed between healthy controls and moderate to heavy active alcohol users. Executive functions, commonly affected by alcoholism and not included in the RBANS, require assessment with additional measures.
