Multiple Sclerosis Day is observed in Russia every June 11, having been celebrated annually since 2010. The day aims to increase awareness about multiple sclerosis and provides healthcare professionals an opportunity to discuss prevention, early diagnosis, and treatment of the disease. Events such as conferences, seminars, lectures, and forums are organized by medical schools, research institutions, and healthcare facilities to educate both the public and professionals about the condition. Multiple sclerosis is a chronic condition that damages the myelin sheaths of nerve cells in the central nervous system, with symptoms often beginning between the ages of 20 and 50. While there is no cure, existing treatments focus on managing symptoms and preventing disability. Additionally, there is a global observance known as World Multiple Sclerosis Day, which takes place on the last Wednesday of May.
