The diagnostic and differential diagnostic value of video electroencephalography in infants less than 1-year-old with non-conclusion seizures / 中国小儿急救医学

ABSTRACT

Objective To discuss the clinical features of non-conclusion seizures(NCS)in infants less than 1 -year-old,and the diagnostic and differential diagnostic value of video electroencephalography (VEEG).Methods A total of 30 NCS patients were took the regular electroencephalography at the first 20 minutes before VEEG monitoring which continued 2 to 4 hours in order to compare the differences between the two monitoring methods,then all patients were taken follow-up after one month,two months,and three months.Results Three cases attacks(accounting for 10.0%)were found by regular electroencephalograph-y,while 23 attacks(accounting for 76.7%)were found by VEEG following no epileptic discharge,either.All patients were found to be corporality NCS,having no psychogenic NCS,among which,19 patients(accounting for 63.3%)were non epileptic tonic-closure seizures,including 2 patients always keeping eyes staring at somewhere,2 patients gritted teeth or grinned,1 patient often put head back,1 patient stretched the neck or necking down,2 patients shrug his shoulders,9 patients shook head,and another 2 always put forth his strength, with or without stiffness,limb jitter,or made face red;on the other,7 patients (accounting for 23.3%)were benign myoclonus,another 4(accounting for 13.3%)were benign non epileptic infant spasm,no other types were found.Nobody had any antiepileptic therapies,15 of them have no more attacks in less than one month,7 in two months,1 in three months,and another 7 appeared occasionly under the conditions of great happiness,extreme an-ger or been raged.Conclusion VEEG have irreplaceable diagnostic and differential diagnostic value in infants less than 1 -year-old with NCS,and play an important role in monitoring the development of NCS.
