The efficiency of short time video-EEG monitorization in diagnosis of seizure-epilepsia classification

Objective: This prospective study was designed for assessing the effectivity of short time (3-4 hours) video-electroencephalography monitorization in classification of localisation associated epilepsia and making differential diagnosis of seizure/pseudoseizure.Material and methods: For this purpose, short time daily (3-4 hours) video- electroencephalography monitorization was applied to 75 children between October 2005 and October 2008. In the first group, 43 children whom attended pediatric neurology service with seizure like complaints altough with no differential diagnosis of seizure, pseudoseizure or paroxysmal disorder mimmicking seizure and normal interictal electroencephalographies was evaluated. Median age was 9,63±3,81 (minimum 3, maximum 17). In the second group, children who attended to hospital with partial seizure complaints and had a diagnosis of seizure type and localisation with history and clinical examination, had normal interictal electroencephalographies, was evaluated and the median age was 9,62±3,77 ( minimum 3, maximum 16).Results: In the first group , 11 children ( % 25,6) had diagnosis of epilepsia as a result of video-electroencephalography monitorization, other children?s had normal results. In the second group, the compatibility of patient?s clinical findings before video-electroencephalography monitorization and diagnosis after video- electroencephalography monitorization has evaluated statistically. When all of the participants added to this study, we found intermediate compatibility between clinical diagnosis and video-electroencephalography monitorization (kappa=0,642). But, when six patients with occipital lobe seizure extracted from this statistical study because of incompatibility between clinical diagnosis and electroencephalography findings, the compatibility was more advanced (kappa= 0,775).Conclusion: Short time daily video-electroencephalography monitorization was more sensitive for finding epileptical discharges and diagnosis of epilepsia, classification of seizure and epileptic syndromes than routine interictal electroencephalography.Keywords: Epilepsy, localisation, seizure/psuedoseizure, short time video- electroencephalography monitorization.
