RACIAL AND GEOGRAPHIC DIFFERENCES IN OCCURRENCE OF NEUROLOGIC DISEASE

这些研究的目的是准确地记录可能的种族， 主要流行病的环境和地理差异 通过调查整个地理定义的人群来研究疾病。的 所研究的疾病包括大脑性麻痹、痴呆、精神发育迟缓， 癫痫、帕金森病、原发性震颤、多发性硬化症和 脑血管疾病 这些神经学研究的研究方案已在 美国（Copiah县）、印度和西班牙。的患病率研究， 印度孟买的Parsi社区提供了 帕金森病为328.3/100，000，基本疾病为1591.7/100，000 震颤在西班牙马德里的一个城市地区进行的试点流行率研究中， 偏头痛和癫痫是最常见的疾病， 患病率分别为163.3/1000和9.3/1000。

The purpose of these studies is to accurately document possible racial, environmental and geographic differentials in the prevalence of major disorders by surveying an entire geographically defined population. The disorders investigated include cerebral palsy, dementia, psychomotor delay, epilepsy, Parkinson's disease, essential tremor, multiple sclerosis and cerebrovascular disease. Research protocols for these neurologic studies have been completed in the United States (Copiah County), India and Spain. The prevalence study of the Parsi Community of Bombay, India provided point prevalence estimates of 328.3/100,000 for Parkinson's disease and 1591.7/100,000 for essential tremor. In the pilot prevalence study in an urban area of Madrid, Spain, migraine and epilepsy were the most frequent disorders with point prevalence ratios of 163.3/1000 and 9.3/1000, respectively.
