F, female; M, male; T, total number.

Ninety‐eight out of 289 patients (34%) had electroclinical epilepsy syndrome as a first diagnosis.

^aSix West syndrome patients, 1 patient with focal epilepsy, and 1 with generalized epilepsy and chromosomal anomaly were evaluated as having Lennox‐Gastaut syndrome (in all 8 patients).
