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， 环境和地理上的差异在主要疾病的患病率上 通过对整个地理定义的人口进行调查，对疾病进行了调查。这个 被调查的疾病包括脑瘫、痴呆症、精神运动延迟、 癫痫、帕金森氏病、特发性震颤、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(科皮亚县)、印度和西班牙。高血压病患者的流行病学研究 印度孟买帕西族社区提供的点流行率估计 帕金森氏症为328.3/100,000，必需的为1591.7/100,000 震颤。在西班牙马德里市区的试点患病率研究中， 偏头痛和癫痫是最常见的穴位障碍 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.
