ObjectiveTo investigate the video-electroencephalography (VEEG) characteristics of old patients with epilepsy (OPWE). MethodsBetween June 2013 and July 2014, 57 OPWE at an age over 60 years were assigned to research group and 65 adults between 16 and 60 years old with epilepsy were regarded as controls. All the subjects underwent VEEG for 24 hours covering awake state and sleep with hyperventilation test being applied. Chi square was used to compare occurrence rate of epileptic wave and abnormal response rate after hyperventilation between the two groups of patients. Additionally, ictal elcetroencephalograph (EEG) was analyzed. ResultsCommon features of waves on EEG for patients in both the two groups during the ictal period included widespread low amplitude fast wave (2 cases in the research group, 7.4%; 4 cases in the control group, 12.5%), focal low amplitude fast wave (5 cases in the research group, 18.5%; 6 cases in the control group, 18.8%), widespread spike or spike slowing complex (3 cases in the research group, 11.1%; 7 case in the control group, 21.8%), focal spike or spike slowing complex (5 cases in the research group, 14.9%; 8 cases in the control group, 25.0%), and focal rhythmic slow wave (6 cases in the research group, 18.5%; 6 cases in the control group, 18.8%). In the research group, there were two following cases:single abnormal background activity in 5 cases (18.5%), and neither abnormal background activity nor epileptic discharge in 1 case (3.7%). Ictal focal epileptic discharges were found in 16 cases in the research group and 8 in the control group (59.3% vs 25.0%), with statistical difference (P<0.05). Inter-ictal epilepsy discharges were found in 57 patients of the research group (awake, 15.8%; sleep, 52.6%), which was less than that in the control group (awake, 46.2%; sleep, 83.1%) with statistical difference (P<0.05), accompanied by focal slow wave (temporal intermittent rhythmic delta activity, TIRDA) in 9 cases. In natural sleep period, epilepsy discharge occurrences increased (65.3%). Abnormal response rate in the research group (14.0%) was lower than that in the control group (64.6%) with statistical difference (P<0.05). ConclusionEarly onset EEG of the old and the adult are similar except those with single abnormal background activity and those with neither abnormal background activity nor epileptic discharge. Focal onset on EEG is more frequently seen in OPWE than in APWE. In natural sleep, epileptic discharge increases among OPWE, and abnormal response during hyperventilation is less likely to happen in OPWE.
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.
Objective To analyze the EEG characteristics and clinical significance of subclinical epilepsy from frontotemporal lobe.Methods A collection of patients with epilepsy who had subclinical seizures monitored by 24-hour video EEG from January 2020 to January 2021 in the Neurology Department of General Hospital of Tianjin Medical University General Hospital, and analyzed the duration of seizures and the number of seizures on the EEG.The characteristics and clinical significance of onset time (sleep period/waking period), interictal discharge, and number of leads involved in seizures.Results A total of 18 patients were enrolled, and 280 clinical seizures (11/18) and 34 clinical seizures (9/18) were captured. Among them, 2 patients had both subclinical seizures and clinical seizures. Frontal lobe origin, 235 subclinical seizures and 15 clinical seizures; temporal lobe origin, 26 subclinical seizures and 19 clinical seizures; frontotemporal lobe origin, subclinical seizures 19 times, no clinical seizures were captured. In the subclinical seizure group (11/18), there were 163 sleep episodes (58.2%) and 117 (41.8%) during waking phase; in the clinical seizure group (9/18), 16 episodes during sleep (47.1%) , 18 seizures (52.9%) in the awake period. Among the leads involved in seizures, <6 leads, 270 subclinical seizures, and no clinical seizures; ≥6 leads, subclinical seizures 10 times, and 34 clinical seizures. In the total duration of seizures: the clinical seizure group was (27.43±17.73) s, with a median value of 30s; the subclinical seizure group was (20.10±15.68) s, with a median value of 13 s. In the analysis of Spearman related factors, the subclinical seizure group was positively correlated with the sleep period (P=0.000), and negatively correlated with the normal nuclear magnetic field (P=0.004).Conclusion The epilepsy originated from the frontotemporal lobe has the characteristics of short clinical seizures, fewer leads involved, more likely to occur during sleep, and subclinical seizures that are more likely to occur when the MRI is abnormal. Therefore, strengthening the monitoring of long-term video EEG for patients with epilepsy and attaching importance to the interpretation of EEG during sleep will help to detect the subclinical seizures of patients and further improve the management of patients with epilepsy.
Objective To explore the actual experience of epileptic patients in video electroencephalogram (VEEG) examination, and to provide reference basis for formulating corresponding nursing strategies and coping methods. MethodsIn this descriptive analysis study, 18 patients (11 males and 7 females, average age 37.78±18.7 years) receiving VEEG from January to April 2022 in the Second Affiliated Hospital of Guangzhou Medical University, underwent a semi-structural interview. Information obtained from the interview was analyzed using the Colaizzi 7-step method. ResultsThe actual experience of epileptic patients in video EEG examination can be summarized into two aspects: the medical experience and the need for nursing care. The medical experience includes positive and negative experience. The positive experience includes good service attitude, professional medical services, good endurance, and being hopeful. The negative experience includes a weird feeling in the head, insomnia, inconvenience in life, eye discomfort, psychological pressure, and pain. The need for nursing care includes needs for knowledge, strong needs for communicating with doctors, needs for humanistic care and female needs for female implementing the equipment. Conclusion Epileptic patients suffer from different degrees of discomfort and psychological pressure during VEEG examination. Both negative and positive experience exist. Medical staff should improve the content of nursing services according to the nursing needs of patients and provide professional VEEG examination services to patients.
