To determine the prevalence of frequently occurring neurologic disorders in a biracial population, a survey of households and chronic care institutions was carried out for all residents of Copiah County, Mississippi. Along with a complete census, interviews were held using extensive questions about diagnoses, signs, and symptoms of neurologic disorders. More than 97% of eligible households participated, comprising 23,842 persons (49% black, 50% white, 1% other). Persons with responses suggesting one or more of these disorders were examined by a neurologist who used defined diagnostic criteria. Age-adjusted prevalence ratios for cerebral palsy, epilepsy, stroke, and severe dementia were somewhat higher in blacks than in whites, while the age-adjusted prevalence ratio for essential tremor was slightly higher in whites. For Parkinson's disease, there was no difference in age-adjusted prevalence ratios between the races.
为确定一个混血人群中常见神经系统疾病的患病率，对密西西比州科皮亚县的所有居民进行了家庭和慢性病护理机构调查。除了全面普查外，还通过广泛询问有关神经系统疾病的诊断、体征和症状进行访谈。超过97%符合条件的家庭参与了调查，涉及23842人（49%为黑人，50%为白人，1%为其他种族）。对那些回答提示患有一种或多种此类疾病的人，由一名神经科医生根据既定诊断标准进行检查。黑人中脑瘫、癫痫、中风和重度痴呆的年龄调整患病率比白人略高，而白人中特发性震颤的年龄调整患病率略高。帕金森病的年龄调整患病率在不同种族之间没有差异。
