OBJECTIVE: To study clinical, electroencephalographic and neuroimaging features in children with epileptic syndromes associated with focal clonic seizures (FCS).
MATERIAL AND METHODS: We examined 1258 patients with various forms of epilepsy with the onset of seizures from the first day of life to 18 years.
RESULTS: FCS was identified in 263 patients (20.9%). FCS were included in the structure of 13 different epileptic syndromes: Rolandic epilepsy (28.1%), structural focal epilepsy (27.5%), structural focal epilepsy associated with benign epileptiform discharges of childhood (SFE-BEDC) (20.6%), focal epilepsy of unknown etiology (7.5%), epilepsia partialis continua (4.6%), pseudo-Lennox syndrome (3.4%), ESES syndrome (2.7%), Landau-Kleffner syndrome (1.5%), Dravet syndrome (1.1%), benign occipital epilepsy (1.1%), benign focal epilepsy in infancy (0.8%), MISF syndrome (0.8%), cognitive epileptiform disintegration (0.8%). In 50% of cases, epilepsy associated with FCS debuts before the age of 5 years (from 1 month to 18 years, average age 4.26±3.9).
CONCLUSION: The groups of syndromes associated with FCS have different prognosis for remission of seizures. Prognostic predictors of seizure remission are: epileptic syndromes associated with BEDC, the presence of periventricular leukomalacia. A severe prognosis for the course of epilepsy is associated with local structural changes in the neocortex. Despite a favorable prognosis for seizures, continued diffuse interictal epileptiform activity with BEDC on the electroencephalogram is a predictor of the onset of cognitive impairment in children.
