Idiopathic generalized epilepsies (IGE) is a group of epilepsies age-dependent, a subgroup of EGG genetic generalized epilepsies, with electro-clinical features and polygenic inheritance. Four syndromes comprising the IGEs: childhood absence epilepsy (CAD), juvenile absence epilepsy (JAE), juvenile myoclonic epilepsy (JME), and generalized tonic-clonic seizures epilepsy. Clinically characterized by the presence of one or a combination of absence seizures, myoclonus, tonic-clonic, or myoclonic-tonic-clonic with common electroencephalographic pat terns of 2.5-5.5 Hz generalized spike-wave and activated by hyperventilation or photic stimulation. They generally have a good prognosis for seizure control, not evolve to an epileptic encephalopathy. Frequent clinical overlap between the first three, being able to evolve between them; the probability and age of remission varies in each one. About 80% responding to broad-spectrum anti-seizure drugs such as valproic acid, may worsen with sodium or GABAergic blockers.

Development is typically normal; however, they are frequently associated with mood disorders, attention-deficit/hyperactivity disorder (ADHD), and learning dis abilities, but do not have cognitive deficits.

The recognition of this group of EGI is important for the adequate use of the resources, avoiding unnecessary studies, adequate orientation of the prognosis and an optimal treatment.
