Study is dedicated to investigation of clinical, electroencephalographic features and chronologic peculiarities of epileptic seizures, associated with focal epilepsy in children with structural changes of brain and benign epileptiformic patterns on EEG. We observed 61 patients at age of 3-22 years old (medium age 11,64 years±4,54). Our study demonstrated the prevalence of secondary generalized seizures (40,9% of cases), focal clonic seizures (37,7% of cases), seizures, coming from occipital cortex. Epileptic seizures were observed at night time (85,3% of cases). In 65,6% of cases seizures were associated only with dream (periods of asleeping, dream and awakening) and were not occuring in wakefulness. In 19,7% of patients seizures occurred in dream as well as in wakefulness. Most often (in 54,1% of patieпts) rare seizures, occurring several time in an year (31,2% of cases), or in single cases in whole period of disease (22,9%).
