<unk>  <unk>  is one of the most frequent pediatrcic epilepsy syndrome.<unk>  is an idiopathic generalized epilepsy that occurs in otherwise normal children, it is also known as genetic epilepsy. The only seizure type at the time of diagnosis is the typical<unk>  seizure that can occur up to hundred time a day. The typical<unk>  seizure has a sudden onset of altered awareness and ends also abruptly. The<unk>  seizures are brief (about 4 to 20 seconds) but occur frequently, sometimes hundreds of times per day, and involve abrupt and severe impairment of consciousness. Mild automatisms are frequent, but major motor involvement early in the course excludes this diagnosis. Electroencephalographs demonstrate characteristic "typical 3Hz spike-wave" discharges.<unk>  is a well-known and common pediatric epilepsy syndrome affecting 10–17% of all children with epilepsy. It was previously known as pyknolepsy. The word pyknolepsy originates from the Greek (picnós), which means recurrent or grouped. The usual age of onset of<unk>  is between 4 and 10 years, with peak between 5 and 7 years. The typical<unk>  seizure has a sudden onset of altered awareness and ends also abruptly. Electroencephalograms demonstrate characteristic "typical 3Hz spike-wave" generalized rythmic discharges that begin and end abruptly. Prognosis is generally good with fair rates of response to treatment and with most patients « growing out » of their<unk> s. However, learning difficulites and seizure occurrence rates remain higher than the general population even after several years. When typical<unk>  seizures start at the age of 8 years or older, when the<unk>  seizures are infrequent or when the<unk>  seizures are observed in a patient that had experienced a generalized tonic-clonic seizure, a diagnosis of juvenile<unk>  epilepsy should be considered.
