Ictal Epileptiform Patterns in Pediatric EEG: Development, Real Waveforms, & Key Mimics_ English VC

This educational presentation provides a practical, developmentally oriented review of ictal epileptiform patterns in pediatric EEG, using real EEG examples and emphasizing the features that help distinguish true seizures from normal developmental transients, benign variants, and artifacts. A central theme is that ictal evolution is more diagnostically important than sharp morphology alone. The presentation explains how seizures evolve in frequency, amplitude, waveform, and spatial distribution, and how these features change from the neonatal period through infancy, childhood, and adolescence. Ictal Epileptiform Patterns – P… Topics include neonatal focal electrographic seizures, epileptic spasms and electrodecrement, focal ictal evolution, typical and atypical absence seizures, generalized convulsive patterns, and important look-alikes such as cone waves, hypnagogic hypersynchrony, 14-and-6-Hz positive bursts, 6-Hz phantom spike–wave, vertex sharp transients, OIRDA, rhythmic temporal activity, and physiologic or movement artifacts. Special attention is given to a structured “ictal or mimic?” approach, incorporating age, vigilance state, cerebral field, evolution, duration, clinical correlation, polygraphy, termination, postictal changes, and syndromic context. The presentation is designed for neurologists, pediatric neurologists, epileptologists, clinical neurophysiologists, EEG fellows, residents, and other clinicians involved in pediatric seizure evaluation. Real EEG examples are derived from the Atlas of EEG Patterns, Second Edition by John M. Stern, alongside the developmental and electroclinical framework summarized in the accompanying literature review. Key learning points Recognize age-dependent pediatric ictal EEG signatures. Identify the four major dimensions of ictal evolution. Distinguish epileptic spasms from other brief motor events. Recognize typical absence EEG patterns and important mimics. Differentiate true focal ictal evolution from benign rhythmic activity. Avoid overdiagnosing sharply contoured normal pediatric variants. Use video, EMG, ECG, respiration, and clinical context to improve diagnostic accuracy.
