受试者新近或近期诊断为癫痫,出现未经诱发的部分性癫痫发作(有明确局灶性的IA、IB、IC),可根据ILAE癫痫发作分类(Commission onClassification and Terminology of the International League Against Epilepsy.Proposal for revised clinical and electrographic classification of epileptic seizures.Epilepsia.1981;22:489-501)进行分类。
受试者接受脑电图检查和脑CT扫描或脑MRI扫描,且根据ILAE癫痫综合征分类(Commission on Classification and Terminology of the InternationalLeague Against Epilepsy. Proposal for revised clinical and electrographicclassification of epileptic seizures. Epilepsia.1981;22:489-501),符合部分性癫痫发作的诊断。如果筛选访视前1年内未进行脑电图检查和脑CT扫描或脑MRI扫描,则需要完成评估,并在随机分组前获得结果。
根据ILAE癫痫和癫痫综合征分类,受试者在随机分组前出现临床或脑电图结果,提示特发性全面性癫痫(Commission on Classification and Terminology of the International League Against Epilepsy. Proposal for revised classification of epilepsies and epileptic syndromes. Epilepsia. 1989;30:389-399)。
