Epidemiology of epilepsy in childhood : A cohort of 440 consecutive patients.
This study analyzes the relative frequency and age of onset of the different seizure types in a 20-year cohort of a pediatric neurology outpatient clinic of an urban hospital that serves the majority of the city's population (Tel Aviv Medical Center).
Only patients with two or more unprovoked seizures were included.
Neonatal seizures were excluded from the analysis.
The different seizure types in descending order of frequency were :
partial seizures secondarily generalized (20.6%), complex partial seizures (12.5%),
West syndrome (9%), simple partial seizures (8.6%), benign rolandic epilepsy of childhood (8%), absence seizures (7%), generalized tonic-clonic seizures (6.6%), generalized tonic seizures (5%), myoclonic seizures (2.2%), benign occipital epilepsy of childhood (2%), mixed type seizures (1.8%),
Lennox-Gastaut syndrome (1.5%), juvenile myoclonic epilepsy (0.9%), atypical absence (0.6%),
Ohtahara syndrome, myoclonic astatic epilepsy, electrical status epilepticus in sleep and startle epilepsy (0.2% each), and unclassified seizures (12%). The findings of this study confirm that there are more pediatric patients with partial seizures (52%) than primary generalized seizures (33%) and that partial seizures secondarily generalized is the most frequent seizure type in this age group.
