"Both stroke and traumatic brain injury are common, costly, and leading causes of severe disability in adults, and approximately 20 percent of strokes occur in adults under age 65," said study author James F. Burke, MD, MS, of the University of Michigan and the Ann Arbor VA Healthcare System and a member of the American Academy of Neurology. "A large proportion of stroke risk is unexplained, especially in the young, so if we can identify new risk factors, we have the potential to prevent more strokes and improve outcomes."   For the study, researchers looked at the records of adults who went to the emergency department or were admitted to a hospital for TBI or other trauma with no brain injury in the state of California during a five-year period.   A total of 435,630 people with traumatic brain injury were studied, along with 736,723 people with trauma with no brain injury. Over an average of 28 months following the injury, 11,229 people, or 1 percent, had an ischemic stroke. A total of 1.1 percent of those with TBI suffered a stroke, compared to 0.9 percent of those with trauma with no brain injury. With an ischemic stroke, blood flow to part of the brain is blocked. Eighty percent of strokes are ischemic（缺血性的）.   After adjusting for factors that can affect stroke risk, such as age, high blood pressure and high cholesterol, as well as other disorders such as heart disease and the severity of the trauma, the researchers found that people with traumatic brain injury were 30 percent more likely to develop a stroke than those with trauma with no brain injury.   "While the stroke risk of one person with TBI is small, the overall link between TBI and stroke was substantial -- as large as the link between the strongest stroke risk factor, high blood pressure, and stroke," Burke said. "If further research establishes TBI as a new risk factor for stroke, that would stimulate research to help us understand what causes stroke after TBI and help us learn how to prevent these strokes." The study was supported by an advanced fellowship through the Department of Veterans Affairs. 有创伤性脑损伤（TBI）的人更可能有未来的行程，根据出现在6月26日网上发行的2013年，神经内科，医学杂志的美国神经病学学会的研究。“中风和脑外伤是常见的，昂贵的，而且成人严重残疾的首要原因，约20％的中风发生在65岁以下的成年人，研究的作者说：”詹姆斯·伯克，博士，硕士，大学密歇根大学和安阿伯VA医疗系统和美国神经病学学会的成员。“中风的风险是很大比例的原因不明，特别是在年轻的，所以如果我们可以识别新的风险因素，我们有潜力，以防止更多的笔触，提高成果。”   在这项研究中，研究人员观察成年人谁去急诊室或在五年期间在加利福尼亚州的无脑损伤被送往一家医院脑外伤或其他创伤。   创伤性脑损伤，共有435630人进行了研究，以及有736723人没有脑损伤与创伤。受伤，11,229人，或1％后，平均28个月以上，有发生缺血性中风。共1.1％，那些与TBI中风，相比那些没有脑损伤创伤的0.9％。随着缺血性中风，血液流向大脑的一部分被封锁。80％的中风是缺血（缺血性的）。   调整因素会影响中风的风险，如年龄，高血压，高胆固醇，以及其他疾病，如心脏疾病和创伤的严重程度后，研究人员发现，人脑外伤的30％以上容易患上中风的风险比那些没有脑损伤创伤。   “当一个人的脑外伤是小中风的风险，脑外伤和中风的整体之间的联系是巨大的 - 大最强的中风危险因素，高血压和中风之间的联系，”伯克说。“如果进一步研究建立TBI作为一种新的中风的危险因素，会刺激研究帮助我们了解是什么原因导致中风脑外伤后，帮助我们了解如何防止这些笔画。” 这项研究是由退伍军人事务部通过先进的奖学金支持。 “成千上万人疯狂下载。。。。。。 更多价值连城的绝密英语学习资料， 洛基内部秘密英语，技巧，策略 请在 网上 申请报名” 洛基国际英语 竭诚为您服务
