Multiple Sclerosis

Multiple sclerosis is a chronic, inflammatory disease that affects the central nervous system and causes gradual destruction of myelin (demyelination) and transection of neuron axons patches throughout the brain and spinal cord . Myelin, the fatty material surrounding the nerves, is destroyed, leading to symptoms such as muscle weakness/paresis/paralysis, spasticity/tremor, and impaired balance, lack of coordination, heat sensitivity, and fatigue.
