A prospective observational study on understanding of idiopathic generalized epilepsies namely juvenile myoclonic epilepsy and epilepsy with generalized tonic-clonic seizure alone by electroencephalogram with updated terminology in a tertiary care hospital

Background: In 2017, the international league against epilepsy (ILAE) classification of epilepsies described “genetic generalized epilepsies”, which contained “idiopathic epilepsies”. This study delineates four syndromes comprising IGEs: childhood absence epilepsy, juvenile myoclonic (JME), and with tonic-clonic seizures alone (GTCA). JME patients usually present seizures, GTCA GTCS only after awakening from sleep. Aim was to identify differences between by semiology EEG updated terminology under observation clinicians.Methods: a prospective observational conducted in clinic, department neurology, Bangabandhu Sheikh Mujib medical university, February 2021 July 2022. The sample size 60. Results: Among 60 patients, family history 12 (20%) 6 (10%) respectively. this study, finding spike-wave (2.5-5.5 Hz) seen 26 (43%) 19 (32%) among Generalized Polyspike wave normal 15 out epilepsy. findings, 2.5-5.5 Hz should be diagnosed as special group IGEs. Conclusions: we have recognized differentiated IGE grouping IGEs is helpful they carry prognostic therapeutic implications.
