Multiple sclerosis (MS) is an inflammatory neurological illness common in young adults. The prevalence and incidence of MS are regionally and globally increasing. Recent data from Saudi Arabia (SA) estimate the prevalence to be 40.40 cases per 100,000 population, and 61.95 cases per 100,000 population for Saudi nationals. With the increasing availability of treatment options, new challenges for treatment selection and approaches have emerged. There is a clear need for national guidelines to standardize practice, guide the personalization of decisions, and contain increasing costs. A multidisciplinary expert panel was formed to develop evidence-based Saudi consensus recommendations on the diagnosis and clinical care of MS, to aid healthcare practitioners in advising patients on treatment decisions. The recommendations were agreed upon after a thorough review, an evaluation of existing international guidelines, and the latest emerging evidence.
