Cognitive Aspects in Multiple Sclerosis

Background: Cognitive dysfunction appears all through the course of multiple sclerosis (MS). Mild and moderate cognitive impairment is present in up to 40% of MS patients and severe cognitive decline affects more than 50% of patients in progressive course of the disease. The most common cognitive disorders in MS include diminished information processing speed, compromised word fluency, complex attention deficit and executive dysfunction. Methods: In this mini review, we present the reader with the most common neuropsychological assessments for the evaluation of cognition in MS, addressing the question of cognitive relapse. Source of data presented in this review is PubMed search of the recently published literature on cognitive decline in MS. Results: Patients with cognitive relapse often fail to meet diagnostic criteria for classical relapse in MS. Although, cognitive decline relates poorly to functional disability in MS, it correlates well with neuropsychological testing and with neuroimaging parameters of the disease. Conclusions: Cognitive decline might be considered as additional indicator of MS activity, and therefore evaluated routinely, irrespective of clinical presentation. Brief cognitive assessment, with confirmed psychometric qualities, might be useful in detection of cognitive relapse in MS patient
