To evaluate the effect of the interval between the seizure and the EEG recording on the yield of early sleep-deprived EEG (SD-EEG) in patients admitted following a presumed first seizure.
We retrospectively reviewed the EEG recordings and medical records of patients admitted to the Neurology Department in Assaf Harofeh Medical Center because of a presumed first seizure during a 3-year period between 2006 and 2009 and who had a SD-EEG following a first routine EEG without epileptiform discharges (EDs).
The study group included 78 patients aged 18-78 years (mean 35 ± 17). Previous seizures were recognized through repeated history in 32 (41%) patients. EDs were recorded in the SD-EEG in 16 (21%) patients: 13/46 (28%) with a SD-EEG performed within 3 days following the seizure and 3/32 (9%) with a later SD-EEG (P = 0.042) and in 10/32 (31%) patients in whom previous seizures were recognized and 6/46 (13%) with a first seizure (P = 0.05).
EDs in the SD-EEG following a first diagnosed seizure occur more commonly when the test is performed within 3 days following a first seizure or when previous seizures are recognized.
评估癫痫发作与 EEG 记录之间的时间间隔对疑似首次癫痫发作后入院患者早期睡眠剥夺 EEG（SD-EEG）产量的影响。
我们回顾性地审查了 2006 年至 2009 年期间在 Assaf Harofeh 医疗中心神经病学部门因疑似首次癫痫发作而入院且在首次常规 EEG 无癫痫样放电（EDs）后进行 SD-EEG 的患者的 EEG 记录和病历。
研究组包括 78 名年龄在 18-78 岁之间的患者（平均年龄 35 ± 17）。32 名（41%）患者通过重复病史确认了之前的癫痫发作。16 名（21%）患者在 SD-EEG 中记录到 EDs：46 名中 13 名（28%）在癫痫发作后 3 天内进行 SD-EEG，32 名中 3 名（9%）进行较晚的 SD-EEG（P = 0.042），其中 10 名（31%）患者在之前的癫痫发作中得到了确认，而 46 名中 6 名（13%）患者出现了首次癫痫发作（P = 0.05）。
在首次诊断性癫痫发作后进行的 SD-EEG 中，如果在首次癫痫发作后 3 天内进行测试或确认之前有癫痫发作，EDs 更常见。
