Executive functioning in relapsing-remitting multiple sclerosis patients without cognitive impairment. A task-switching protocol
Background: Cognitive dysfunction affects 40%–65% of multiple sclerosis (MS) patients, most often affecting information processing speed and working memory, mediated by the pre-frontal cortex (PFC). Objective: Our study aimed to investigate PFC functioning through a task-switching protocol in relapsing-remitting multiple sclerosis (RRMS) patients without cognitive impairment. Methods: A total of 24 RRMS patients and 25 controls were enrolled.
