Evaluating Neurocognitive Deficits in Patients With Multiple Sclerosis Via a Brief Neuropsychological Approach.
Recent research demonstrates neurocognitive deficits are present early in the sequelae of multiple sclerosis (MS). This is an important consideration given the functional activities of daily living, such as employment, that can be impacted by neurocognitive dysfunction. This study investigated the utility of a brief neuropsychological battery, the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), to evaluate neurocognitive deficits in patients with MS and to examine the relationship between a measure of functional disability (Expanded Disability Status Scale [EDSS]) and the RBANS. Participants were 49 patients with MS (Mage = 45.39 years) who completed the RBANS as part of a neuropsychological assessment and 49 demographically matched healthy controls (Mage = 45.39 years). Multivariate analysis of variance revealed that the two groups differed on the RBANS. Descriptive discriminant analysis indicated the groups differed on domains of attention, language, immediate memory, and delayed memory. EDSS scores were a good predictor of neurocognitive dysfunction in patients with advanced disability but not for patients with mild disability. The RBANS seems to be effective in identifying cognitive dysfunction in patients with MS, and caution should be used in extrapolating cognitive deficits for patients with low EDSS scores.
