Juvenile absence epilepsy

Juvenile absence epilepsy manifests with severe and frequent absence seizures, as well as generalized tonic-clonic seizures in a majority of patients, with typical onset between 9 to 13 years of age. Abrupt, brief impairment of consciousness with total or partial unresponsiveness is the defining feature of the absence.

Childhood occipital epilepsy of Gastaut

Childhood occipital epilepsy of Gastaut manifests with frequent and brief visual seizures consisting of elementary visual hallucinations, blindness, or both, commonly with postictal headache. Motor seizures and hemiconvulsions can also occur. Onset is typically in late childhood or early teenage years.

Early myoclonic encephalopathy

Ohtahara syndrome

Ohtahara syndrome is one of the earliest developing forms of epileptic encephalopathy. The main characteristics of the syndrome are tonic seizures and a suppression-burst pattern on EEG. Although the condition was classically attributed to structural brain damage, it has increasingly been associated with a variety of genetic mutations as well. Prognosis is very poor.
