The Brief Repeatable Battery of Neuropsychological Tests: normative values allow application in multiple sclerosis clinical practice

The Brief Repeatable Battery of Neuropsychological Tests (BRB-N) is a sensitive measure of cognitive impairment in multiple sclerosis (MS) patients. It consists of the Selective Reminding Test, the 10/36 Spatial Recall Test, the Symbol Digit Modalities Test, the Paced Auditory Serial Addition Test and the Word List Generation Test. We administered one of two parallel versions of the test battery to 140 healthy subjects to produce normative values for both versions. As expected, test scores were influenced by certain variables like age, gender and education. Although constructed as two equivalent versions, for some tests the two versions showed significant differences in test scores, which could not be explained by differences in these variables.
