Objective: determination of the clinical and epidemiological features of familial multiple sclerosis (MS) in the population of Rostov-on-Don. Material and Methods. Subjects of the research were patients with idiopathic inflammatory demyelinating diseases (HDD) numbering 806 people, among them 710 people with MS according to McDonald criteria (2010, 2017), living in Rostov-on-Don. Results. In the analyzed population 78 family cases were revealed; among them was a patient with clinically isolated syndrome (CIS), one with radiologically isolated syndrome (RIS) in 44 families. The general risk of repetition in the population demyelinating account for 3.7%. The prevalence rate of the familial MS in the population was 6.9 per 100000 people. In the male-to-female correlation for cases of familial MS makes 1:3.5. In most analyzed cases of familial MS (61.2%), a woman had the disease. The onset age in the first generation was considerably higher than the one in the following generations, on average 13.1±4.8 years more. The first remission continued 2.6 years in the familial MS group. In the group of the familial MS, the average disease development speed is 0.8±0.3 points per year. An analysis of clinical features revealed a predominance of polysymptomatic debut, which was noted in 20.63% of cases. Conclusion. A burdened family history in patients with MS may bean unfavorable prognostic factor for the aggressive course of the disease, and given the predominance of women as "progenitors", it is possible to suggest the role of mitochondria in the pathogenesis of the disease.
