Localisation in focal epilepsy: a practical guide

The semiology of epileptic seizures reflects activation, or dysfunction, areas brain (often termed the symptomatogenic zone) as a seizure begins and evolves. Specific semiologies in focal epilepsies provide an insight into location onset zone, which is particularly important for presurgical epilepsy assessment. correct diagnosis paroxysmal events also depends on clinician being familiar with spectrum semiologies. Here, we summarise current literature localisation using illustrative cases discussing possible pitfalls localisation.
