Screening tests for the evaluation of cognitive impairment in multiple sclerosis patients

Multiple sclerosis (MS), the most common autoimmune neurological disease of young people, is a significant burden for the patient, significantly decreasing the quality of life. Besides motor deficits, sensory problems, and vision loss, in recent years, neurologists have focused also on the cognitive impairment related to this condition. The early detection of cognitive disturbances is currently an essential part of MS patients’ follow-ups, as any worsening suggests the inefficiency of the applied treatment and the need for a therapeutic switch. In this regard, this review aims to highlight the importance of cognitive screening tests in the periodical evaluation of MS patients. While in the first part, the most frequently used cognitive screening tests in Romania are presented in a detailed manner, in the second part of the article, the clinical impact of these tests is highlighted, based on the results of the most relevant randomized clinical trials published during the last 10 years. Finally, the authors suggest future research directions to improve cognitive screening testing in MS patients after exposing the limitations of currently used screening batteries.
