Generalized epilepsy is a form of epilepsy characterised by generalised seizures with no apparent cause. Generalized seizures, as opposed to focal seizures, are a type of seizure that impairs consciousness and distorts the electrical activity of the whole or a larger portion of the brain (which can be seen, for example, on electroencephalography, EEG).
Generalized epilepsy is primary because the epilepsy is the originally diagnosed condition itself, as opposed to secondary epilepsy, which occurs as a symptom of a diagnosed condition.
Generalized seizures can be either absence seizures, myoclonic seizures, clonic seizures, tonic-clonic seizures or atonic seizures.
Generalized seizures occur in various seizure syndromes, including myoclonic epilepsy, familial neonatal convulsions, childhood absence epilepsy, absence epilepsy, infantile spasms (West's syndrome), Juvenile Myoclonic Epilepsy, Lennox-Gastaut syndrome and Generalized epilepsy with occipital semiology.
Most generalized epilepsy starts during childhood. While some patients outgrow their epilepsy during adolescence and no longer need medication, in others, the condition remains for life, thereby requiring lifelong medication and monitoring.
Seven anti-epileptic drugs are approved for use in cases of suspected primary generalized epilepsy:
Brand Name: Felbatol Generic Name: Felbamate
Levetiracetam
Zonisamide
Topiramate
Valproate
Lamotrigine
Perampanel
Valproate, a relatively old drug, is often considered the first-line treatment. It is highly effective, but its association with fetal malformations when taken in pregnancy limits its use in young women.
All anti-epileptic drugs (including the above) can be used in cases of partial seizures.

La crise d'épilepsie généralisée tonico-clonique est un type de crise épileptique généralisée. Elle se décompose en . La première est la chute, avec une perte de connaissance immédiate. S'ensuit une phase de raidissement des membres, les yeux sont révulsés et le corps est cyanosé, la respiration est bloquée (phase tonique d'environ ). Viennent ensuite la phase clonique, avec trémulation des membres (environ ), puis la phase de coma post-traumatique épileptique, phase post-ictale, avec un relâchement des urines ; la personne est dans un coma de niveau 3.
Reflex seizures are epileptic seizures that are consistently induced by a specific stimulus or trigger making them distinct from other epileptic seizures, which are usually unprovoked. Reflex seizures are otherwise similar to unprovoked seizures and may be focal (simple or complex), generalized, myoclonic, or absence seizures. Epilepsy syndromes characterized by repeated reflex seizures are known as reflex epilepsies. Photosensitive seizures are often myoclonic, absence, or focal seizures in the occipital lobe, while musicogenic seizures are associated with focal seizures in the temporal lobe.
In the field of neurology, seizure types are categories of seizures defined by seizure behavior, symptoms, and diagnostic tests. The International League Against Epilepsy (ILAE) 2017 classification of seizures is the internationally recognized standard for identifying seizure types. The ILAE 2017 classification of seizures is a revision of the prior ILAE 1981 classification of seizures. Distinguishing between seizure types is important since different types of seizures may have different causes, outcomes, and treatments.
