    Still very confused
    If a part of your body becomes hard then does it count as a disease?
    Are scabs diseases?

    This means that the extracellular matrix, the molecules that are surrounded and interacting with the cells in the organ changes its properties because of the disease, so the cells are less comfortable in their environment and behave in an abnormal way. In the case of multiple sclerosis, this happen in the central nervous system (brain and spinal cord) mainly because of the loss of myelin that surrounds the axons of our neurons. These axons are crucial for the transmission of the electrical impulse responsible of our senses among other things. I hope that now is more clear 🙂
