WebEpileptiform Activity Interictal epileptiform activity includes spikes, sharp waves, and paroxysmal fast activity, and their combinations with slow waves, such as spike-and-wave complexes (spike followed by a slow wave) and polyspike-and-wave complexes (multiple spikes followed by a slow wave). From: Handbook of Clinical Neurology, 2012 Ictal WebJun 6, 2024 · Interictal epileptiform discharges (IEDs), meaning spikes, polyspikes, sharp waves, or spike and slow-wave complexes without observed clinical seizures, are commonly observed in children with epilepsy. Neuropsychological evidence indicates that childhood epilepsy often has negative effects on cognitive function [ 2 ].

Criteria for defining interictal epileptiform discharges in EEG

WebDuring generalized seizures, the EEG typically shows diffuse rhythmic activity or repetitive epileptiform activity, reflecting initial involvement of both cerebral hemispheres. Tonic and atonic seizures are characterized by a sudden appearance of generalized low-voltage fast activity, suppression, spike–wave complexes or rhythmic activity. WebMay 19, 2024 · Pitfalls for correct ED identification include overinterpretation of the EEG and can lead to misdiagnosis of people who do not have epilepsy. 5 The initial criteria adopted by the International Federation of Clinical Neurophysiology (IFCN) to distinguish EDs are not sufficient to separate pathologic EDs from normal features of the EEG. 6 …
