1. Localization-related (focal, local, partial) epilepsies and syndromes
1.1. Idiopathic with age-related onset
A. Benign childhood epilepsy with centrotemporal spikes
B. Childhood epilepsy with occipital paroxysms
1.2. Symptomatic
A. Chronic progressive epilepsia partialis continua of childhood
B. Syndromes characterized by seizures with specific modes of precipitation
C. Temporal lobe epilepsies
D. Frontal lobe epilepsies
E. Parietal lobe epilepsies
F. Occipital lobe epilepsies
1.3 Crytopgenic
2. Generalized epilepsies and syndromes
2.1. Idiopathic, with age-related onset (listed in order of age)
A. Benign neonatal familial convulsions
B. Benign neonatal convulsions
C. Benign myoclonic epilepsy in infancy
D. Childhood absence epilepsy (pyknolepsy)
E. Juvenile absence epilepsy
F. Juvenile myoclonic epilepsy (impulsive petit mal)
G. Epilepsy with grand mal seizures on awakening
H. Other generalized idiopathic epilepsies not defined above
I. Epilepsies with seizures precipitated by specific modes of activation
2.2. Idiopathic and/or symptomatic (listed in order of age)
A. West syndrome (infantile spasms)
B. Lennox-Gastaut syndrome
C. Epilepsy with myoclonic-astatic seizures
D. Epilepsy with myoclonic absences
2.3. Symptomatic

3. Epilepsies and syndromes undetermined as to whether they are focal or generalized
3.1. With both generalized and focal seizures
A. Neonatal seizures
B. Severe myoclonic epilepsy in infancy
C. Epilepsy with continuous spike waves during slow-wave sleep
D. Acquired epileptic aphasia (Landau-Kleffner syndrome)
E. Other undetermined epilepsies not defined above
3.2. Without unequivocal generalized or focal features
4. Special syndromes
4.1. Situation-related seizures
A. Febrile convulsions
B. Isolated, apparently unprovoked epileptic events
C. Seizures related to other identifiable situations such as stress, hormonal changes, drugs, alcohol, or sleep deprivation
