Cognitive Function in Multiple Sclerosis: A Subcortical Pattern of Neuropsychological Impairment?
Abstract
In order to evaluate cognitive impairment in multiple sclerosis (MS) neuropsychological tests were administered to 25 patients with clinically definite disease. Four (16%) showed diffuse cognitive impairment, whereas the others, compared with controls showed a specific deficit on tests known to be sensitive to frontal lobe damage. These results are interpreted in the light of current hypotheses relating to subcortical contributions in cognition.
