摘要: Over 50 million people worldwide live with the consequences of brain and spinal cord injury. Unfortunately, nervous system tissue is very fragile its protection by bones skull vertebral column insufficient to withstand forces encountered in motor vehicle accidents or during contact sports. Though our understanding primary secondary injury excellent, effective therapeutics enhance a patient’s recovery are largely absent. At best, rehabilitation robotic assist devices make disease more manageable. The major hurdles inability most neurons replicate after injury, active, multipronged suppression axonal regeneration myelin-associated molecules glial scars. Exciting progress has been made overcoming these preclinical studies, clinical trials show promise implantation autologous stem cells. Increased public awareness danger associated repeated mild injuries sporting activities having positive effects on use protective measures athletics.
