Epilepsy is a very complex disorder of the central nervous system. It is characterized by a sudden, disordered and excessive neuronal shock that causes different clinical evidences with specific related electroencephalogram (EEG). Psychogenic Non-Epileptic Seizures (PNES) can seriously complicate the diagnosis of epilepsy. The separoxysmal events have the same clinical evidences of epilepsy, such as an impairment of the self-control and a range of sensory, motor and mental manifestations, without the typical related electroencephalogram (EEG) because of the absence of an organic cause. The overwhelming majority of Psychogenic Non-Epileptic Seizures are related to psychological factors like dissociation. This is a defense mechanism used to cope stressful events or emotional conflicts. Psychological or psychiatric disorders, like Post Traumatic Stress Disorder (PTSD), are frequently associated to Psychogenic Non-Epileptic Seizures. In this article, we present a case report of epilepsy combined with Psychogenic Non-Epileptic Seizures. A joint intervention is of great significance in this occurrence. The subject received a psychological assessment including psychometric and projective tools. He stood MMPI-2, Wais-R, SCL-90, Rorschach test and graphic tests. A psychological disorder related to defense mechanisms was identified. The subject presents a tendency to convert his fears and emotive pains in rational and more socially acceptable problems, using his body to express his discomfort. Patient with epileptic seizures should receive a psychological assessment to exclude Psychogenic Non-Epileptic Seizures. Further studies should propose guidelines to integrate neurological, psychiatric and psychological intervention. 展开更多

MOST cases of encephalitis are caused by viruses but a few have an immunological basis, such as paraneoplastic encephalitis, with specific antibodies identified. One recently characterized encephalitis caused by antibodies is anti-N- methyl-D-aspartate (NMDA) receptor encephalitis. It is a form of paraneoplastic limbic encephalitis associated with ovarian teratoma and has recently been described.The NMDA receptor mediates excitatory neurotransmission. It is important for synaptic plasticity, and thus for higher function such as learning and memory. This disorder results in prominent psychiatric symptoms followed by a rapid decline of the level of consciousness, central hypoventilation, seizures, involuntary movements and dysautonomia. 展开更多

Distinguishing non-epileptic events,especially psychogenic non-epileptic seizures(PNES),from epileptic seizures(ES)constitutes a diagnostic challenge.Misdiagnoses are frequent,especially when video-EEG recording,the gold-standard for PNES confirmation,cannot be completed.The issue is further complicated in cases of combined PNES with ES.In emergency units,a misdiagnosis can lead to extreme antiepileptic drug escalade,unnecessary resuscitation measures(intubation,catheterization,etc.),as well as needless biologic and imaging investigations.Outside of the acute window,an incorrect diagnosis can lead to prolonged hospitalization or increase of unhelpful antiepileptic drug therapy.Early recognition is thus desirable to initiate adequate treatment and improve prognosis.Considering experience-based strategies and a thorough review of the literature,we aimed to present the main clinical clues for physicians facing PNES in non-specialized units,before management is transferred to epileptologists and neuropsychiatrists.In such conditions,patient recall or witness-report provide the first orientation for the diagnosis,recognizing that collected information may be inaccurate.Thorough analysis of an event(live or based on home-video)may lead to a clinical diagnosis of PNES with a high confidence level.Indeed,a fluctuating course,crying with gestures of frustration,pelvic thrusting,eye closure during the episode,and the absence of postictal confusion and/or amnesia are highly suggestive of PNES.Moreover,induction and/or inhibition tests of PNES have a good diagnostic value when positive.Prolactinemia may also be a useful biomarker to distinguish PNES from epileptic seizures,especially following bilateral tonic-clonic seizures.Finally,regardless the level of certainty in the diagnosis of the PNES,it is important to subsequently refer the patient for epileptological and neuropsychiatric follow-up. 展开更多

Certain amino acids changes in the human Na^(+)/K^(+)-ATPase pump,ATPase Na^(+)/K^(+)transporting subunit alpha 1(ATP1A1),cause Charcot-Marie-Tooth disease type 2(CMT2)disease and refractory seizures.To develop in vivo models to study the role of Na^(+)/K^(+)-ATPase in these diseases,we modified the Drosophila gene homolog,Atpα,to mimic the human ATP1A1 gene mutations that cause CMT2.Mutations located within the helical linker region of human ATP1A1(I592T,A597T,P600T,and D601F)were simultaneously introduced into endogenous Drosophila Atpαby CRISPR/Cas9-mediated genome editing,generating the Atpα^(TTTF)model.In addition,the same strategy was used to generate the corresponding single point mutations in flies(Atpα^(I571T),Atpα^(A576T),Atpα^(P579T),and Atpα^(D580F)).Moreover,a deletion mutation(Atpα^(mut))that causes premature termination of translation was generated as a positive control.Of these alleles,we found two that could be maintained as homozygotes(Atpα^(I571T)and Atpα^(P579T)).Three alleles(Atpα^(A576T),Atpα^(P579)and Atpα^(D580F))can form heterozygotes with the Atpαmut allele.We found that the Atpαallele carrying these CMT2-associated mutations showed differential phenotypes in Drosophila.Flies heterozygous for Atpα^(TTTF)mutations have motor performance defects,a reduced lifespan,seizures,and an abnormal neuronal morphology.These Drosophila models will provide a new platform for studying the function and regulation of the sodium-potassium pump. 展开更多

BACKGROUND The SETD1B gene is instrumental in human intelligence and nerve development.Mutations in the SETD1B gene have been linked in recent studies to neurodevelopmental disorders,seizures,and language delay.CASE SUMMARY This study aimed to analyze the clinical manifestations and treatment of three patients suffering from mental retardation,epilepsy,and language delay resulting from a new mutation in the SETD1B gene.Three individuals with these symptoms were selected,and their clinical symptoms,gene test results,and treatment were analyzed.This article discusses the impact of the SETD1B gene mutation on patients and outlines the treatment approach.Among the three patients(two females and one male,aged 8,4,and 1,respectively),all exhibited psychomotor retardation,attention deficit,and hyperactivity disorder,and two had epilepsy.Antiepileptic treatment with sodium tripolyvalproate halted the seizures in the affected child,although mental development remained somewhat delayed.Whole exome sequencing revealed new mutations in the SETD1B gene for all patients,specifically with c.5473C>T(p.Arg1825trp),c.4120C>T(p.Gln1374*,593),c.14_15insC(p.His5Hisfs*33).CONCLUSION Possessing the SETD1B gene mutation may cause mental retardation accompanied by seizures and language delay.Although the exact mechanism is not fully understood,interventions such as drug therapy,rehabilitation training,and family support can assist patients in managing their symptoms and enhancing their quality of life.Furthermore,genetic testing supplies healthcare providers with more precise diagnostic and therapeutic guidance,informs families about genetic disease risks,and contributes to understanding disease pathogenesis and drug research and development. 展开更多

Network approaches have been widely accepted to guide surgical strategy and predict outcome for epilepsy treatment.This study starts with a single oscillator to explore brain activity,using a phenomenological model capable of describing healthy and epileptic states.The ictal number of seizures decreases or remains unchanged with increasing the speed of oscillator excitability and in each seizure,there is an increasing tendency for ictal duration with respect to the speed.The underlying reason is that the strong excitability speed is conducive to reduce transition behaviors between two attractor basins.Moreover,the selection of the optimal removal node is estimated by an indicator proposed in this study.Results show that when the indicator is less than the threshold,removing the driving node is more possible to reduce seizures significantly,while the indicator exceeds the threshold,the epileptic node could be the removal one.Furthermore,the driving node is such a potential target that stimulating it is obviously effective in suppressing seizure-like activity compared to other nodes,and the propensity of seizures can be reduced 60%with the increased stimulus strength.Our results could provide new therapeutic ideas for epilepsy surgery and neuromodulation. 展开更多

Introduction: Seizures are one of the most common neurological complications in the infant period. The aim of our study was to describe the epidemiological, clinical, therapeutic and prognostic features of seizures in infants at the Albert Royer Children’s Hospital (Senegal). Materials and Methods: This was a retrospective, descriptive study from 1 January 2012 to 30 September 2018 of infants aged 0 days to 2 months who presented with seizures. Results: The hospital rate was 8.5%. Almost all the mothers (99.1%) had undergone at least 3 antenatal visits. Urogenital infection, gestational arterial hypertension and funicular anomalies were the main pregnancy-related pathologies. Delivery was vaginal in the majority of cases (80.9%). Most infants (43.6%) had not cried at birth. The majority of infants (63%) were born at term. Trophicity was normal in 68% of cases. The average age of the infants was 6.7 days. The main causes of seizures were hypoxic-ischemic encephalopathy (48.7%), metabolic disturbances (48.1%) and central ոеrvοսѕ system infections (15.6%). Phenobarbital was the 1st-line anticonvulsant. The case fatality rate was 39.5%. The main sequela observed were delayed psychomotor development (20.6%). Conclusion: Optimal management of infant seizures requires early diagnosis and etiological treatment by improving the quality of perinatal care to ensure better management of risk factors, as well as increasing the availability of neuroimaging equipment. 展开更多

Background: We present a compelling case fitting the phenomenon of cortical spreading depression detected by intraoperative neurophysiological monitoring (IONM) following an intraoperative seizure during a craniotomy for revascularization. Cortical spreading depression (CSD, also called cortical spreading depolarization) is a pathophysiological phenomenon whereby a wave of depolarization is thought to propagate across the cerebral cortex, creating a brief period of relative neuronal inactivity. The relationship between CSD and seizures is unclear, although some literature has made a correlation between seizures and a cortical environment conducive to CSD. Methods: Intraoperative somatosensory evoked potentials (SSEPs) and electroencephalography (EEG) were monitored continuously during the craniotomy procedure utilizing standard montages. Electrophysiological data from pre-ictal, ictal, and post-ictal periods were recorded. Results: During the procedure, intraoperative EEG captured a generalized seizure followed by a stepwise decrease in somatosensory evoked potential cortical amplitudes, compelling for the phenomenon of CSD. The subsequent partial recovery of neuronal function was also captured electrophysiologically. Discussion: While CSD is considered controversial in some aspects, intraoperative neurophysiological monitoring allowed for the unique analysis of a case demonstrating a CSD-like phenomenon. To our knowledge, this is the first published example of this phenomenon in which intraoperative neurophysiological monitoring captured a seizure, along with a stepwise subsequent reduction in SSEP cortical amplitudes not explained by other variables. 展开更多

The reactor coolant pump(RCP)rotor seizure accident is defined as a short-time seizure of the RCP rotor.This event typically leads to an abrupt flow decrease in the corresponding loop and an ensuing reactor and turbine trip.The significant reduction of core coolant flow while the reactor is being operated at full load can have very negative consequences.This potentially dangerous event is typically characterized by a complex transient behavior in terms of flow conditions and energy transformation,which need to be analyzed and understood.This study constructed transient flow and rotational speed mathematical models under various degrees of rotor seizure using the test data collected from a dedicated transient rotor seizure test system.Then,bidirectional fluid-solid coupling simulations were conducted to investigate the flow evolution mechanism.It is found that the influence of the impeller structure size and transient braking acceleration on the unsteady head(Hu)is dominant in rotor seizure accident events.Moreover,the present results also show that the rotational acceleration additional head(Hu1)is much higher than the instantaneous head(Hu2). 展开更多

BACKGROUND Gelastic seizure(GS)is a rare type of epilepsy that most commonly appears in patients with hypothalamic hamartoma.It is rarely associated with other types of brain damage.This particular type of epilepsy is relatively rare and has few links to other brain lesions.Temporal lobe malacia is mostly caused by cerebral infarction or cerebral hemorrhage,which can lead to seizures.We report a case of GS in a woman with temporal lobe malacia which was reported for the first time in the literature.CASE SUMMARY A 73-year-old female,diagnosed case of GS,presented with repetitive stereotyped laughter a month prior to presentation,happening multiple times daily and with each time lasting for 5-15s.Electroencephalogram displayed a focal seizure seen in the right temporal region.Magnetic resonance imaging head with contrast showed a right temporal lobe malacia.The patient was started on levetiracetam daily.The patient indicated that they had fully recovered and were not experiencing any recurrent or stereotyped laughter during their daily routines.These results remained consistent even after a one-year follow-up period.CONCLUSION GS can be caused by temporal lobe malacia,which is an uncommon but potentially grave condition.The outcome of this present case exhibited the importance of the temporal lobe in the genesis of GS. 展开更多

BACKGROUND Non-ketotic hyperglycaemic(NKH)seizures are a rare neurological complication of diabetes caused by hyperglycaemia in non-ketotic and non-hyperosmotic states.The clinical characteristics of NKH seizures are atypical and lack unified diagnostic criteria,leading to potential misdiagnoses in the early stages of the disease.CASE SUMMARY This report presents a rare case of NKH seizures in a 52-year-old male patient with a history of type 2 diabetes mellitus.We performed comprehensive magnetic resonance imaging(MRI)studies at admission,12 d post-admission,and 20 d post-discharge.The imaging techniques included contrast-enhanced head MRI,T2-weighted imaging(T2WI),fluid-attenuated inversion recovery(FLAIR),diffusion-weighted imaging,susceptibility-weighted imaging,magnetic reso-nance spectroscopy(MRS),and magnetic resonance venography.At the time of admission,T2WI and FLAIR of the cranial MRI showed that the left parieto-occipital cortex had gyrus-like swelling and high signal,and subcortical stripes had low signal.MRS showed a reduced N-acetylaspartate peak and increased creatine and choline peaks in the affected areas.A follow-up MRI 20 d later showed that the swelling and high signal of the left parieto-occipital cortex had disappeared,and the low signal of the subcortex had disappeared.CONCLUSION This case study provides valuable insights into the potential pathogenesis,diagnosis,and treatment of NKH seizures.The comprehensive MRI findings highlight the potential utility of various MRI sequences in diagnosing and characterizing NKH seizures. 展开更多

BACKGROUND The generalized tonic-clonic seizure(GTCS)is the most usual variety of epileptic seizure.It is mainly characterized by strong body muscle rigidity,loss of consciousness,a disorder of plant neurofunction,and significant damage to cognitive function.The effect of antiepileptic drugs on cognition should also be considered.At present,there is no effective treatment for patients with epilepsy,but traditional Chinese medicine has shown a significant effect on chronic disease with fewer harmful side effects and should,therefore,be considered for the therapy means of epilepsy with cognitive dysfunction.AIM To investigate the clinical efficacy of Baijin pills for treating GTCS patients with cognitive impairment.METHODS This prospective study enrolled patients diagnosed with GTCS between January 2020 and December 2023 and separate them into two groups(experimental and control)using random number table method.The control group was treated with sodium valproate,and the experimental group was Baijin pills and sodium valproate for three months.The frequency and duration of each seizure,the Montreal Cognitive Assessment Scale(MoCA),and the Quality of Life Rating Scale(QOLIE-31)were recorded before and after treatment.RESULTS There were 85 patients included(42 in the control group and 43 in the experimental group).After treatment,the seizure frequency in the experimental group was significantly reduced(P<0.05),and seizure duration was shortened(P<0.01).The total MoCA score in the experimental group significantly increased compared to before treatment(P<0.01),and the sub-item scores,except naming and abstract generalization ability,significantly increased(P<0.05),whereas the total MoCA score in the control group significantly decreased after treatment(P<0.05).The QOLIE-31 score of the experimental group increased significantly after treatment compared to before treatment(P<0.01).CONCLUSION Baijin pills have a good clinical effect on epilepsy with cognitive dysfunction. 展开更多

BACKGROUND Seizures are one of the most common neurological complications encountered in the intensive care unit(ICU).They can occur in the background of exacerbation of a known neurological disease or secondary to non-neurological conditions such as sepsis and metabolic disturbances.However,there is a paucity of literature on the incidence and pattern of new-onset seizures in ICUs.AIM To study the incidence and patterns of new-onset seizures in patients admitted to the medical ICU.METHODS This was a prospective,multicenter,observational study performed in two tertiary care centers in Hyderabad,India over a period of 1 year.Patients upon ICU admission,who developed new-onset generalized tonic clonic seizures(GTCS),were enrolled.Those with a pre-existing seizure disorder,acute cerebrovascular accident,head injury,known structural brain lesions,or chronic liver disease were excluded as they have a higher likelihood of developing seizures.All enrolled patients were subjected to biochemical routines,radiological imaging of either computed tomography or magnetic resonance imaging,and other relevant laboratory tests as per clinical suspicion according to the protocol,and their data were recorded.Statistical analyses were conducted using descriptive statistics,χ^(2) tests,and linear regression.RESULTS A total of 61 of 2522 patients developed GTCS.Among all etiologies of seizures,metabolic causes were most frequent(35%)followed by infective causes(27%)and others(new-onset structural,drug withdrawal,druginduced,toxicology-related,and miscellaneous factors).Logistic regression analysis showed that increased sodium and calcium levels were associated with a lower likelihood of developing seizures.CONCLUSION This study identified the etiology of new-onset seizures developing in critically ill patients admitted to the ICU.These findings highlight the need for targeted monitoring of those at risk of developing seizures. 展开更多

Background: Cystic echinococcosis is a zoonotic infection that occurs worldwide. Humans are infected through ingestion of parasite eggs in contaminated food, water or through direct contact with infected dogs, which are the definite host. Humans serve accidentally as intermediate host, and occurrences are common in children and young adults. Cystic echinococcosis is endemic in Mediterranean, South American, Middle Eastern, Central Asia, East Africa countries and Australia. Multiple cerebral hydatid cysts are very rare with only a few reports in the literature. Case Description: We present the case of an 8-year-old girl who presented with focal seizures, hemiparesis, headache, vomiting and bilateral optic atrophy. Diagnostic workup was performed, and magnetic resonance imaging revealed multiple intracranial cysts predominantly in the right frontal region with significant mass effect. A total of 11 intracranial cysts were removed surgically, and the child recovered uneventfully. Conclusion: Neurosurgeons should keep hydatidosis in the list of differentials when evaluating patients with cystic diseases of the brain. Although the removal of such cysts is challenging, outcomes are excellent when cysts are evacuated without rupture and patients show complete resolution of symptoms. 展开更多

Objective Measuring the serum concentrations of adrenocorticotropic hormone (ACTH) and cortisol in epileptic seizures during sleep to investigate their link to the EEG changes. Methods Pre-surgical evaluation was performed by videoEEG monitoring using 24 channel recording. Thirty six epilepsy patients could be attributed to two groups: 28 patients had spontaneous seizures, and the other 8 patients whose seizures were induced by bemegride. Another 11 persons with confirmed psychogenic non-epileptic seizures (PNES) served as control group. Blood samples were obtained at five points: wake (08:00 a.m.), sleep (00:00 a.m.), and shortly before, during and after an epileptic seizure. The serum ACTH and cortisol were measured and analyzed by chemiluminescent immunoassay. Results The levels of ACTH and cortisol in serum underwent significant changes: declining below the average sleep-level shortly before seizures, increasing during seizures, and far above the average wake-level after seizures (P 〈 0.001). Such changes did not occur in the control group (P 〉 0.05). The ACTH and cortisol levels had no significant difference between spontaneous group and bemegride-induced group (P 〉 0.05). Conclusion The serum concentrations of ACTH and cortisol during sleep seizures are linked with pre-ictal and ictal EEG changes in epilepsy patients. 展开更多

Extracts from Rhizoma Acori Tatarinowii (Grassleaf Sweetflag Rhizome, Shichangpu) have been shown to improve learning and memory, reduce anxiety, allay excitement, and suppress seizures. Rhizoma Acori Tatarinowii extracts interact with y-aminobutyric acid and activate the y-aminobutyric acid type A receptor, although few studies have addressed the precise effects of v-aminobutyric acid type A receptor al subunit. In the present study, y-aminobutyric acid type A receptor al subunit protein expression in the cerebral cortex and hippocampus, and pathological scores of brain injury, were significantly greater following recurrent seizures, but significantly decreased following treatment with Rhizoma Acori Tatarinowii extracts. These results indicated that Rhizoma Acori Tatarinowii extracts down-regulated y-aminobutyric acid type A receptor al subunit protein expression in the cerebral cortex and hippocampus and protected seizure-induced brain injury during development. 展开更多

Our previous study showed that when glutamate receptor (GluR)6 C terminus-containing peptide conjugated with the human immunodeficiency virus Tat protein (GluR6)-9c is delivered into hippocampal neurons in a brain ischemic model, the activation of mixed lineage kinase 3 (MLK3) and c-Jun NH2-terminal kinase (JNK) is inhibited via GluR6-postsynaptic density protein 95 (PSD95). In the present study, we investigated whether the recombinant adenovirus (Ad) carrying GluR6c could suppress the assembly of the GluR6-PSD95-MLK3 signaling module and decrease neuronal cell death induced by kainate in hippocampal CA1 subregion. A seizure model in Sprague-Dawley rats was induced by intraperitoneal injections of kainate. The effect of Ad- Glur6-9c on the phosphorylation of INK, MLK3 and mitogen-activated ldnase kinase 7 (MKK7) was observed with western immunoblots and immunohistochemistry. Our findings revealed that overexpression of GluR6c inhibited the interaction of GluR6 with PSD95 and prevented the kainate-induced activation of INK, MLK3 and MKK7. Furthermore, kainate-mediated neuronal cell death was significantly suppressed by GluR6c. Taken together, GluR6 may play a pivotal role in neuronal cell death. 展开更多

BACKGROUND: Studies have explored changes in neonatal rat glucocorticoid receptor (GR) expression changes following mature brain injury. OBJECTIVE: To investigate the temporal and special changes of GR during brain development in rats with recurrent seizures. DESIGN, TIME AND SE'n'ING: A randomized, controlled animal experiment was performed at the Department of Pediatrics, Second Xiangya Hospital of Central South University, from February 2008 to March 2009. MATERIALS: Rabbit anti-rat GR monoclonal antibody was purchased from Santa Cruz Biotechnology, USA; goat anti-rabbit IgG was purchased from Zhongshan Goldenbridge Biotechnology, China. METHODS: A total of 48 Sprague-Dawley rats, 7 days old, were randomly assigned to control and seizure groups, with 24 animals in each group. Seizures were induced by inhalant flurothyl. MAIN OUTCOME MEASURES: Changes in GR protein expression in the rat cerebral cortex were detected by Western blotting analysis and immunohistochemistry. RESULTS: GR expression in the cerebral cortex of control rats significantly increased with aging (P 〈 0.05), and varied in the frontal lobe, temporal lobe, and parietal lobe. GR was predominantly expressed in the cytoplasm early and rapidly increased in the nuclei. GR protein expression in the cerebral cortex after seizure was lower in the cytoplasm at 15 days and in nuclear protein at 19 days. CONCLUSION: GR expression displayed temporal and spatial changes in brain development. Recurrent seizures in neonatal rats cause abnormal GR expression and might play an important role in developing brain injury. 展开更多

Objective: To report cases of neurocysticercosis(NCC) from three neighboring districts of Andhra Pradesh state in India where NCC burden was never explored before.Methods: A total of 160 patients presenting with recent onset seizures were recruited from neurology, general medicine, and pediatric outpatient clinics of a local major tertiary care teaching hospital serving above districts during the period 2011–2014. Brain imaging was performed in all the above cases. A commercial immunoglobulin G-ELISA kit(sensitivity = 85%; specificity = 94%) was employed for the serological diagnosis of NCC.Results: The recruited patients presented with generalized, simple partial, and complex partial seizures(55%, 31.25% and 13.75% respectively). NCC was diagnosed in 44 of160(27.5%) seizure cases based on imaging characteristics, and a positive serum antibody ELISA. No association was detected between seropositivity with the number and location of the lesion(s) in the brain.Conclusions: The possible potentiality of NCC could be identified as an underlying cause of the recent onset of seizures in this region as explored in the present study. It is recommended that NCC should be suspected as one of the major differential in every recent onset seizure with or without a radio imaging supportive diagnosis, especially in areas endemic for taeniasis/cysticercosis. 展开更多
