Although myelination is largely complete by two years of age, clinical seizure manifestations continue to evolve beyond this age (probably reflecting the caudorostral pattern of brain development), with an adult pattern of semiology unlikely before age 6 years. A high index of suspicion is therefore required when evaluating the clinical description of events for focality. The assessment will have obvious management implications, particularly for the diagnosis of an epilepsy syndrome. Most studies evaluating seizure semiology have been performed in surgical cohorts, where documentation of seizure type is made with video EEG telemetry and confirmed by seizure freedom after removal of the suspect area.
