A need for prevalence information emphasizing racial differences prompted a door-to-door survey of all residents of Copiah County, Mississippi. The fieldwork involved a complete census and an extensive screening questionnaire inquiring about diagnoses, signs, and symptoms of neurologic disease. Residents who lived in institutions or had screening responses suggestive of epilepsy were requested to have an examination by neurologists who used defined diagnostic criteria. Prevalence day was 1 January 1978, and the survey yielded prevalence ratios of 1,043/100,000 inhabitants for epilepsy and 678/100,000 inhabitants for active epilepsy. Age-adjusted prevalence ratios were somewhat higher for males and for blacks. Of the 246 identified cases of epilepsy, 37% were judged symptomatic. The leading (putative) cause was head trauma, especially among white males. About 57% of the 246 cases had been evaluated previously by a neurologist or neurosurgeon, while 7% had never been evaluated medically before the survey.
由于需要有关强调种族差异的患病率信息，因此对密西西比州科皮亚县的所有居民进行了挨家挨户的调查。实地调查包括全面普查和一份广泛的筛查问卷，询问神经系统疾病的诊断、体征和症状。居住在机构中的居民或筛查结果提示患有癫痫的居民被要求由使用明确诊断标准的神经科医生进行检查。患病率调查日为1978年1月1日，该调查得出癫痫的患病率为每10万居民中有1043例，活动性癫痫的患病率为每10万居民中有678例。年龄调整后的患病率男性和黑人略高。在246例确诊的癫痫病例中，37%被判定为症状性癫痫。主要（假定）病因是头部外伤，尤其是在白人男性中。在这246例病例中，约57%此前曾由神经科医生或神经外科医生进行过评估，而7%在调查前从未接受过医学评估。
