[Adolescence epilepsy--a clinical, electroencephalographical and prognostic study (author's transl)]

Epileptic seizures are almost as common in adolescence as in childhood. They have the same etiologies or, more often, lack any etiology, However, their clinical and electroencephalographical features are different. Primary generalized epilepsy is chiefly represented by clonic-tonic seizures, with or without myoclonias. The prognosis is better if only one type of seizure is present. Secondary generalized epilepsies are very rare. Partial epilepsies, almost as frequent as generalized epilepsies, are represented by either elementary or complex partial seizures. Elementary partial seizures are more common and usually of good prognosis. The prognosis is poor for complex partial seizures.
