Researchers are also working on options to prevent or repair axon damage. Axon are the long, thin extensions that connect nerve cells together, they are needed to help a person regain most abilities, including walking. Apoptosis which is a process of cell suicide, called a death of cell, scientists are testing several neuroprotective chemicals that might shield nerve cells from such death. Other therapies are intense rehabilitation, electrical stimulation, neuroplasticity, treatment therapy and stem cells. Research that could lead to medical techniques: That can stem the increasing damage that occurs in weeks, following a spinal cord injury. New treatments that can repair damaged nerve cells.
