Objective To investigate the clinical and EEG characteristics, therapeutic response and prognosis in children with atypical absence seizures. Methods The clinical and EEG data of 43 children with atypical absence seizures in Qilu Hospital, Shandong University during January 2011 to December 2016 were analyzed, and therapeutic response and prognosis were followed up. Results Childre were 24 male and 19 female with the mean age of 5.43 y. The onset ages were from 1 years and 8 months to 10 years and 3 months. All of the 43 patients had MRI examines, and 18 children were normol. MRI abnormalities appeared in 25 children, including cerebral cortical dysplasia and cerebral atrophy (13 cases), congenital corpus callosum hypoplasia (2 cases), and abnormal signal in bilateral posterior putamen (2 cases), encephalomalacia focus(4 cases), ventricle expention (2 cases), hydrocephalus(2 cases). All the children underwent EEG more than once. All children had atypical absence seizures during daytime. Children had slowly backgrounds in retesting EEG, and spine and slow waves of 1.5 Hz to 2.8 Hz could be seen in all the atypical absence seizures. All children were followed up, and except 6 children with complete control, 19 children’ parents reported seizure- free, 18 children have poor effect. Forty Children had various degrees of psychological abnormalities and motor regression. Among them 13 cases had psychological abnormalities and motor regression before disease; cognitive ability of 27 cases were normal before onset age, however, about 75% to 95% of the children became abnormal 2 years after atypical absence seizures. The rest 3 cases had no obviously impairment. Conclusions Most of the atypical absence seizures children had small onset age and high incidence in mental damage and cognitive impairment. The course of typical absence seizures aggravate gradually, and often develops to nonspecific brain damage in this process. Antiepileptic drugs can reduce the frequency of the seizure in part of the patients, but had no effect on psychological and motor regression.
ObjectiveTo study the clinical and EEG features, therapeutic response and prognosis of eyelid myoclonia-nonconvulsive status epilepticus (EM-NCSE) in children.MethodsCollected the clinical and EEG data of 3 children with EM-NCSE that were diagnosed in department of neurology in Qilu Children Hospital of Shandong university during the January in 2015 to August in 2016.Analysed the therapeutic response to antiepletic drugs(AEDs).ResultsAmong the three children, there were 2 girls and 1 boy.The age at the onset of the disease was from 6 to 10 years old.The average age of them is 8.67 years old.The clinical manifestations include mental confusion, dysphoria, winking and scrolling up the eyes.The typical vedio electroencephalography (VEEG) in the patients showed 3~6 Hz generalized spike and waves and polyspikes burst, especially in the frontal and the anterior temporal region.In addition, the eye closure and intermittent photic stimulation helped to induce discharges and clinical events as eyelid myoclonia (EM).ConclusionsEM-NCSE is one of the idiopathic and generalized epileptic disease and characterized by EM.Video EEG monitoring plays an important role in the diagnosis of this disease.The drugs of choice for treatment was diazepam.When the event was controlled, AEDs were effective for the following therapy.
