Introduction - The only Hungarian video EEG laboratory where children of ages 0-18 can be continuously monitored for several days was opened 1 June 2001 at Department of Neurology of Bethesda Children's Hospital. Objectives - Summarizing our 10 years of experience with the video EEG monitoring (VEM) of children and defining the place of VEM in the treatment of childhood epilepsy in Hungary. Patients and methods - We have processed data from 597 monitoring sessions on 541 patients between June 1, 2001 and 31 May, 2011 based on our database and the detailed summaries of the procedures. Results - 509 patients were under the age of 18. The average length of the sessions was 3.1 days. We have observed habitual episodes or episodes in question in 477 (80%) sessions. 241 (40%) sessions were requested with an epilepsy surgery indication, and 74 patients had 84 operations. 356 (60%) were requested with a differential diagnosis indication, and 191 (53%) cases of epilepsy were diagnosed. We most commonly diagnosed symptomatic generalized epilepsy (57 cases). In 165 sessions the episode in question was not diagnosed as epilepsy. Among the paroxysmal episodes we have identified events of psychogenic origin, movement disorders, sleep disorders and behavioral disorders. Only 3% of the differential diagnosis procedures brought no additional clinical information. Discussion - The diagnostic efficiency in our VEM laboratory is in accordance with the data found in the literature. Besides epilepsy surgery VEM is recommended if suspected epileptic episodes occur and interictal epileptiform signs are not present or are not in accordance with the symptoms, if there is no explanation for therapy resistance and if paroxysmal episodes of non-epileptic origin are suspected but they cannot be identified based on the anamnesis. VEM is also helpful in diagnosing subtle seizures. The procedure has numerous additional benefits in patient care and in training the parents and hospital staff.
