Usefulness of short term video-EEG monitoring in children with frequent intractable episodes.

A prospective study was done to evaluate the role of short-term Video EEG (VEEG) recording in assessing the nature of clinical behaviour and in classification of seizures in children with frequent intractable seizure episodes. Forty five children upto 12 years of age with frequent intractable seizure episodes (> or =3/week) were included in the study. VEEG was done on an outpatient basis until an event was recorded or for a minimum period of 6 hours. The events were detected in 78% of cases. The seizures were classified in all children with recorded events and seizure classification was changed in 22%. Anti-epileptic drugs could be stopped or reduced in 11%. Short term VEEG monitoring was useful in characterising events and in classification of seizures in children with frequent, intractable seizure episodes. Use of this investigation as a screening procedure for diagnosis in children with frequent episodes is stressed, thereby reducing the cost associated with prolonged VEEG recordings and disability associated with misdiagnosis of epilepsy.
