Y1 - 2011 N1 - T2 - Atlas of Video-EEG Monitoring AB - Generalized tonic-clonic (GTC) seizures may be either primary or secondary in onset.1 Although the older terms grand mal, convulsion, and fit are still widely used by patients, the preferred terminology of tonic-clonic seizure derives from intensive correlative analysis of GTC clinical seizure semiology with simultaneous ictal electroencephalography (EEG), and implies a usual prototypical progressive sequence of clinical movements that often help distinguish this seizure type from other predominantly motor, primarily generalized, or partial-onset seizure types (i.e., myoclonic, tonic, and extratemporal partial seizures) and from psychogenic or physiologic nonepileptic spells.1 SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/18 UR - neurology.mhmedical.com/content.aspx?aid=1103049288 ER -
