MORTALITY FROM NEUROLOGIC DISORDERS--NATIONAL AND INTERNATIONAL COMPARISONS

虽然死亡证明数据受到可能误诊的限制， 不完整的病例确认、编码错误等，详细死亡率 关于整个美国的一些神经系统疾病的信息， available.死亡率数据的分析对某些人特别有用， 神经系统疾病，因为这些疾病可能间接导致死亡。以来 没有统一的标准，什么构成的根本原因， 在病人的死亡，重要的是要检查所有死亡，其中一种疾病 被列为潜在的、直接的、相关的或促成的原因， 死亡，以获得更完整的信息之间的关系 疾病和死亡。死亡时发生的疾病相关性 也正在研究美国发生的所有死亡事件， 神经系统疾病同时发生的疾病可能提供重要的 寻找疾病病因的信息。 对亨廷顿舞蹈症的死亡率数据进行了详细的分析， 疾病（死亡时的合并症）、弗里德赖希病（生存 年平均数的国际比较 神经系统原发性肿瘤和中风的死亡率 （危险因素的病例对照研究）。

Although death certificate data are limited by possible misdiagnosis, incomplete case ascertainment, errors in coding, etc., detailed mortality information on some neurologic diseases for the entire U.S. is not available. Analysis of mortality data can be particularly useful for some neurologic diseases because these may contribute to death indirectly. Since there are no uniform criteria for what constitutes the underlying cause of death in patients, it is important to examine all deaths in which a disease is listed as an underlying, immediate, associated, or contributory cause of death to get more complete information about the relationship between the disease and death. Association of diseases occurring at the time of death are also being studied for all deaths occurring in the U.S. for many neurologic diseases. Diseases occurring together may provide important information in the search for etiology of diseases. Detailed analyses of mortality data have been accomplished for Huntington's disease (comorbidity at time of death), Friedreich's disease (survival analysis), international comparisons of average annual age-adjusted mortality rates for primary tumors of the nervous system, and stroke (case-control study of risk factors).
