Analysis of Video-EEG in Frontal Lobe Seizures

Objective To evaluate clinical features,ictal and interictal EEG characteristics in the patients diagnosed as frontal lobe epilepsy. Methods Clinical data and EEG findings were subject to the comparison in 30 cases based on routine and long term video-EEG(VEEG) recordings, especially on 12 frontal seizures recorded. Results 12 ictal seizures showed the characteristics of typical frontal lobe origin as follows: postural seizures,gestural automatism,vocalization,adversive seizures and changes in expressions. Frontal lobe seizures were often exhibited in relatively short durations,whereas the frequent nocturnal attacks usually occurred without postictal mental confusion. The ictal epileptic discharges might be of assistance for their diagnoses in view of the lack of interictal EEG positive findings in some cases. Conclusion Practically the frontal lobe epilepsy is not so uncommon. Ictal monitoring using video-EEG might be helpful for its diagnosis and treatment.
