Multiple sclerosis (MS) is a progressive autoimmune disorder affecting the protective coverings of nerve cells and is more common in women, typically diagnosed between ages 20 and 40. The exact cause is unknown, but genetic factors, viruses, and environmental influences may contribute, with symptoms ranging from fatigue to severe cases causing paralysis. While there is no cure, treatments aim to slow progression and manage symptoms, emphasizing the importance of early medical consultation, particularly for those with a family history of MS.
