The aim of this paper is to study the clinical, electroencephalographic features, response to treatment and the outcome of juvenile myoclonic epilepsy in Libyan patients. A total of 12 patients with prevalence of 1.7% among 704 patients with epilepsies, 3 males(25%), 9 females(75%), age of onset is between (9-17 years) with a mean of 13.8 years, myoclonic jerks were the presenting symptoms in 7(58.4%) patients , 4(33.3%) of them their myoclonic jerks(MJ) were severe enough to make them fall down to the ground, generalized tonic clonic seizures(GTCS) in 5(41.6%) patients, one(8.3%) patient had symptoms of typical absence(TA) in association with the (MJ), no family history of epilepsy was found in all patients. Waking interictal electroencephalographic features showed normal background in all the 12(100%) patients, 3(25%) patients were photosensitive with characteristic 4 HZ/sec spike and wave. All 12(100%) patients responded well to small dose of sodium valproate 600mg/day and were seizure free for 3years.
