The medical records of 27 children admitted to the MINCEP Epilepsy Program for evaluation of intractable epilepsy but later shown to have nonepileptic events by EEG with simultaneous video monitoring were reviewed. Four groups were identified: pure psychogenic events (5 patients), psychogenic events plus epileptic seizures (3 patients), pure nonepileptic physiologic events (5 patients), and nonepileptic physiologic events plus seizures (14 patients). Historical data, physical examinations, and neurodiagnostic evaluations (including previous EEGs, neuroradiologic evaluations, and neuropsychologic testing) were reviewed. Children in all groups, except for those with pure psychogenic seizures, had a history of multiple seizure types identified by parents or caretakers. A history of status epilepticus was obtained in 64% (of 22 patients), including 11 of 14 patients with physiologic events plus seizures. Abnormal findings on neurologic examination were common, especially in children with nonepileptic physiologic events. All but two patients had a history of interictal epileptiform abnormalities on previous routine EEGs. Based on identification of nonepileptic events, antiepileptic drugs (AEDs) were discontinued completely in eight patients (30%) and the total number of AEDs was reduced in nine others (33%). A diagnosis of nonepileptic events should be considered in all children with refractory seizures or multiple seizure types. Abnormal findings on routine (interictal) EEG may actually confound the diagnosis. Intensive neurodiagnostic EEG-video recording is the preferred method for distinguishing nonepileptic from epileptic seizures.
Objectives Super refractory status epilepticus (SRSE) is a stage beyond refractory status that requires general anesthesia as management. Electroconvulsive therapy (ECT) is recommended only as a potential treatment option beyond general anesthesia and after all other options have been exhausted. Its effect on aborting status has been minimally researched. We present the largest case series to our knowledge exploring the effect of ECT on SRSE. Methods Eight adults hospitalized for SRSE received ECT in an attempt to abort status after other treatment modalities were exhausted. Electroconvulsive therapy consisted of a 504-mC (≈99.4 J) stimulus delivered bifrontotemporally with a constant 0.5-millisecond pulse width. Seizure activity during ECT was monitored visually and correlated to the single-channel recording provided by the apparatus. Results There was neurotelemetry or clinical evidence of improvement within 24 hours after the full course of ECT treatment in 5 (63%) of the 8 cases. Cases that improved were given an average of 7.8 total ECT stimulations, eliciting an average of 4.2 total seizures. Conclusions Although it is difficult to determine the exact role of ECT in the improvement of 63% of our cases, we present a series of patients for whom pharmacotherapy, ketogenic diet, and general anesthesia otherwise did not produce an appreciable effect on status prior to implementation of ECT. These findings suggest that cases of SRSE may benefit from ECT administration.
