There is a great deal of ongoing research in multiple sclerosis, and there continues to be a focus on the immune system in investigational therapies. In addition, scientists are trying to develop techniques that allow brain cells to generate new myelin or that prevent the death of nerves. Other promising approaches include the use of precursor (neuronal stem or progenitor) cells that could be implanted into the brain or spinal cord to repopulate areas of missing cells. Future therapy may involve methods designed to improve impulses traveling over the damaged nerves. Scientists also are exploring the effects of diet and other environmental factors on multiple sclerosis.
