MORTALITY FROM NEUROLOGIC DISORDERS--NATIONAL AND INTERNATIONAL COMPARISONS

尽管死亡证明数据受到可能的误诊的限制， 病例查明不完整、编码错误等、详细死亡率 关于整个美国一些神经疾病的信息并不是 可用。对死亡率数据的分析可能对某些人特别有用 神经系统疾病，因为这些疾病可能间接导致死亡。自.以来 对于什么构成的根本原因没有统一的标准 在病人死亡时，检查所有死亡病例中的一种疾病是很重要的 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，关于 疾病和死亡。死亡时发生的疾病的关联性 也在研究在美国发生的所有死亡事件 神经系统疾病。一起发生的疾病可能会提供重要的 在寻找疾病病因学方面的信息。 亨廷顿病的死亡率数据已经完成了详细的分析 疾病(死亡时共病)、Friedreich病(存活率 分析)，经年龄调整的年均国际比较 神经系统原发肿瘤和中风的死亡率 (危险因素病例对照研究)。

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).
