EEG was abnormal in 42 patients (70%) showing generalized, 4- to 6-Hz polyspike and wave in 27 (45%), generalized single spike/ sharp waves in 7 patients (11.6%), 8 (13.3%) patients had 3-Hz spike-and-wave (SW) activity in addition to the polyspike-and-wave (PSW) pattern. Diagnosis by referring physicians was JME in only 6 (10%) patients. Family history for epilepsy was positive in 20%. Most common precipitating factors were sleep deprivation in 80% and fatigue in 66.6%. First seizure type was MJ in 52 (86.6%) and absence in 8 (13.3%). Myoclonic jerks (MJ) were present in all patients, GTCS in 52 (86.6%), and absence seizures in 8 (13.33%) patients. Average delay in the diagnosis was 5.2 years. Mean age at the onset of myoclonic jerks (MJ) and generalized tonic clonic seizures (GTCS) was 13.7 ± 2.12 years and 14.15 ± 1.79 years respectively. Results: Out of 60 patients, 26 (43.3%) were males and 34 (56.6%) were females. After detailed history clinical examination, Electroencephalography (EEG) with standard protocol was performed in all patients and was analyzed by a neurologist. Methods: In this descriptive case series study, 60 patients of Juvenile myoclonic epilepsy (JME) were included. Objective : To determine the clinical and electroencephalographic characteristics of patients with Juvenile Myoclonic Epilepsy (JME).
