Background. The interest is caused by reports about the month of birth (MB) impact on the development and course of multiple sclerosis (MS). The purpose is to analyze the anamnestic data of MS patients, depending on the MB, season and month of MS onset; to clarify the relationship between MB and the development of MS in terms of comorbidity. Materials and methods. 216 MS patients with various forms of course were examined and were divided into 2 groups: without concomitant diseases (n = 109) and with concomitant diseases (n = 107). The distribution of patients is analyzed depending on MB, the season and month of MS onset. Results. It was found that most often MS patients were born in May — 56 (25.9 %) persons in the general group, 31 (29.0 %) — in the group with concomitant diseases and 25 (23.0 %) — in the group without concomitant diseases. As for the month of MS onset: most often, it was April (14.7 % of the patients of the group without concomitant diseases and 21.5 % of the group with concomitant diseases). Conclusions. The months prognostically unfavorable for the birth of MS patients are May and April, and in terms of the incidence of MS debut — April.
