The study of symptomatology and electroencephalogram in central region diastematia epilepsy / 中华神经科杂志

ObjectiveTo explore the clinic symptom and the characteristics of video,tightly close,intracranial electroencephalogram (EEG) of patients with central region diastematia epilepsy. Methods Retrospective analysis of 9 patients with central region diastematia epilepsy admitted from June,2007 to August,2009.The characteristics of all patients' seizure symptom and EEG manifestation were analyzed using patients' medical history,video and EEG records.ResultsPatients with central region diastematia epilepsy had relatively long sezure history.The duration of seizure was commonly short,with frequent episode and no obvious intelligence impairment.The seizure was often accompanied with the hyperkinesia in the lower limbs.Scalp EEG showed discharges with low amplitude waves in the mean line area.The superhigh amplitude and regular rhythm slow sharp wave could be found in the diastematia cortex EEG.All patients had an Engel Class Ⅰ outcome after surgery.ConclusionThe seizure symptoms are characteristic in the patients with central region diastematia epilepsy,and some special manifestations can be found in different phase,wave amplitude,rhythm,lead array.

The combination application of intracranial buried electrode and cortical electrical stimulation in the excision of the epileptogenic zone in the central zone / 中国神经精神疾病杂志

Objective To investigate the combination application of the intracranial buried electrode and electrical stimulation techniques in excising the epileptogenic zone in the central zone.Methods Seven patients with epileptogenic zone located close to or in the central zone of brain were recruited in the present study.The lone term ECoG monitoring and electrical stimulation of the codex were performed to identify the epileptogenic zone and the central zone of the brain after patients received intracranial electrode implants.The epileptogenic zone was excised with maximum preservation of the cen-tral zone.The patients were follow-up for 6 to 12 months,the outcomes were evaluated based on the Engel's scale and the Karnofsky(KPS)score.Results Seven patients did not experience any seizures and their Engei's and KPS scores were markedly improve after operation.Conclusions Intracranial buried electrodes and cortical electrical stimulation can guide the resection of epileptogenic zone in the central zone.Patients have no seizure and no serious dysfunction after operation and their quality of life was improved markedly.
