  • 文章类型: Journal Article
    癫痫是一种由复杂的相互作用引起的疾病,涉及过度的神经元电活动和氧化应激,这可能导致慢性神经系统疾病。这项研究评估了包裹在SLNC中的藏红花素对神经保护和对抗戊四氮(PTZ)诱导的氧化损伤的作用。在用PTZ诱导之前,用SLNC和FC(25,50mg/kg/天;P.O.)预处理大鼠28天。进行了各种标准测试来评估他们的行为功能,比如Y迷宫,野外试验(OFT),和高架迷宫(EPM)测试。ELISA测定脑组织过氧化氢酶活性(CAT)和一氧化氮状态(NO)。通过免疫组织化学和高尔基Cox染色检测核因子κB(NF-κB)的表达和树突棘的数量,分别。SLNC加PTZ预处理大鼠能显著提高Y型迷宫的记忆力,降低焦虑水平,OFT,和EPM测试。此外,它降低了NO水平,增加了CAT水平。SLNC还显示NF-κB表达显着降低,神经元和棘数量增加。SLNC在改善PTZ注射后的记忆和学习缺陷方面的积极作用可归因于其抗炎和抗氧化作用。
    Epilepsy is a condition resulting from complex interactions involving excessive neuronal electrical activity and oxidative stress, which can lead to chronic neurological conditions. This study evaluates crocin encapsulated in SLNC for neuroprotective and countering pentylenetetrazole (PTZ) -induced oxidative damage. The rats were pre-treated with SLNC and FC (25, 50 mg/kg/day; P.O.) for 28 days before being induced with PTZ. Various standard tests were conducted to assess their behavioral functions, such as Y-maze, Open field test (OFT), and elevated plus maze (EPM) tests. ELISA measured brain tissue catalase activity (CAT) and nitric oxide status (NO). The expression of Nuclear factor kappa B (NF-κB) and the number of dendrite spines were examined through Immunohistochemical and Golgi-Cox staining, respectively. The Pretreating rats with SLNC plus PTZ significantly boosted memory and reduced anxiety levels in Y-maze, OFT, and EPM tests. In addition, it decreased NO levels and increased CAT levels. SLNC also showed a significant decrease in NF-κB expression and an increase in neurons and the number of spines. The positive effects of SLNC in improving memory and learning deficits after PTZ injection can be attributed to its anti-inflammatory and anti-oxidative effects.

    精神性非癫痫发作(PNES),与癫痫发作(ES)非常相似,通常由心理困扰引发,代表临床实践中遇到的最普遍的转换障碍形式。多种身体状况可以沉淀和维持PNES发作。癫痫,一种常见的神经系统疾病,施加了巨大的情感和身体负担,经常导致焦虑和抑郁水平升高。该病例报告详细介绍了一名19岁女性的临床过程,该女性的PNES因癫痫的诊断和疾病负担而加剧。病人童年创伤的背景,欺凌,性虐待可能使她倾向于发展PNES。在接受癫痫诊断后,以起源于左顶叶区域的局灶性癫痫发作为特征,患者焦虑加剧,需要频繁住院.尽管她调整了治疗方案,包括左乙拉西坦(LEV)和拉科沙胺(LCM),她的癫痫发作持续。综合评价,包括脑电图(EEG)和单光子发射计算机断层扫描(SPECT),表明癫痫和PNES共存。尽管最初考虑了手术干预,它最终被认为是不必要的,随后缓解了患者的焦虑。通过持续的药物治疗来强调癫痫的可管理性的心理教育显着减少了她的PNES发作。这个案例强调了解决与癫痫诊断相关的社会心理负担的关键作用。因为这些因素可能会加剧PNES。它还强调了将心理支持与医疗管理相结合的整体治疗方法的重要性。
    Psychogenic non-epileptic seizures (PNES), which closely resemble epileptic seizures (ES), are typically triggered by psychological distress and represent the most prevalent form of conversion disorder encountered in clinical practice. Multiple physical conditions can both precipitate and sustain PNES episodes. Epilepsy, a common neurological disorder, imposes significant emotional and physical burdens, frequently resulting in elevated levels of anxiety and depression. This case report details the clinical course of a 19-year-old female whose PNES was exacerbated by the diagnosis and disease burden of epilepsy. The patient\'s background of childhood trauma, bullying, and sexual abuse likely predisposed her to the development of PNES. Upon receiving a diagnosis of epilepsy, characterized by focal seizures originating from the left parietal region, the patient experienced increased anxiety and required frequent hospitalizations. Despite adjustments to her treatment regimen, including the administration of levetiracetam (LEV) and lacosamide (LCM), her seizures persisted. Comprehensive evaluations, comprising electroencephalography (EEG) and single-photon emission computed tomography (SPECT), indicated the coexistence of epilepsy and PNES. Although surgical intervention was initially considered, it was ultimately deemed unnecessary, which subsequently alleviated the patient\'s anxiety. Psychoeducation highlighting the manageability of her epilepsy with ongoing pharmacotherapy significantly reduced her PNES episodes. This case emphasizes the critical role of addressing the psychosocial burden associated with an epilepsy diagnosis, as these factors may exacerbate PNES. It also underscores the importance of a holistic treatment approach that integrates psychological support with medical management.

    神经元凋亡是用于清除细胞氧化应激或DNA损伤并改善功能性神经元回路的最终神经元数量的机制。肿瘤抑制蛋白p53是细胞周期的关键调节因子,是消除高DNA损伤神经元的检查点,过度增殖信号或细胞应激。在开发过程中,p53主要在祖细胞中表达。在成年人的大脑中,p53的表达仅限于神经源性小生境,在那里它调节细胞增殖和自我更新。研究皮质和海马中p53缺失的功能后果,我们产生了条件突变小鼠(p53-cKO),其中p53从苍白祖细胞及其衍生物中删除。令人惊讶的是,与对照小鼠相比,我们未发现海马区突变皮质或CA区的神经元数量有任何显著变化.然而,p53-cKO小鼠在齿状回的颗粒下区域表现出更多的增殖细胞,在颗粒细胞层中表现出更多的颗粒细胞。与对照同窝小鼠相比,p53-cKO小鼠中CA3区域的谷氨酸能突触更多,这与突变小鼠的过盈性和更高的癫痫易感性相关。
    Neuronal apoptosis is a mechanism used to clear the cells of oxidative stress or DNA damage and refine the final number of neurons for a functional neuronal circuit. The tumor suppressor protein p53 is a key regulator of the cell cycle and serves as a checkpoint for eliminating neurons with high DNA damage, hyperproliferative signals or cellular stress. During development, p53 is largely expressed in progenitor cells. In the adult brain, p53 expression is restricted to the neurogenic niches where it regulates cell proliferation and self-renewal. To investigate the functional consequences of p53 deletion in the cortex and hippocampus, we generated a conditional mutant mouse (p53-cKO) in which p53 is deleted from pallial progenitors and their derivatives. Surprisingly, we did not find any significant change in the number of neurons in the mutant cortex or CA region of the hippocampus compared with control mice. However, p53-cKO mice exhibit more proliferative cells in the subgranular zone of the dentate gyrus and more granule cells in the granular cell layer. Glutamatergic synapses in the CA3 region are more numerous in p53-cKO mice compared with control littermates, which correlates with overexcitability and higher epileptic susceptibility in the mutant mice.

    拓扑数据分析(TDA)在神经科学领域越来越被认为是一种有前途的工具,揭示大脑信号中潜在的拓扑模式。然而,大多数与TDA相关的方法将大脑信号视为静态信号,即,它们忽略了信号统计特性中潜在的非平稳性和不规则性。在这项研究中,我们开发了一种新颖的基于分形维数的测试方法,该方法考虑了大脑信号的动态拓扑特性。通过将EEG大脑信号表示为Vietoris-Rips过滤序列,我们的方法适应了信号固有的非平稳性和不规则性。我们新颖的基于分形维数的测试方法在分析癫痫发作期间EEG信号的动态拓扑模式中的应用揭示了0、1和2维同源性的总持久性的显着变化。这些发现暗示了癫痫对大脑信号的更复杂的影响,超越单纯的振幅变化。
    Topological data analysis (TDA) is increasingly recognized as a promising tool in the field of neuroscience, unveiling the underlying topological patterns within brain signals. However, most TDA related methods treat brain signals as if they were static, i.e., they ignore potential non-stationarities and irregularities in the statistical properties of the signals. In this study, we develop a novel fractal dimension-based testing approach that takes into account the dynamic topological properties of brain signals. By representing EEG brain signals as a sequence of Vietoris-Rips filtrations, our approach accommodates the inherent non-stationarities and irregularities of the signals. The application of our novel fractal dimension-based testing approach in analyzing dynamic topological patterns in EEG signals during an epileptic seizure episode exposes noteworthy alterations in total persistence across 0, 1, and 2-dimensional homology. These findings imply a more intricate influence of seizures on brain signals, extending beyond mere amplitude changes.

    电惊厥疗法(ECT)被广泛认为是各种精神疾病最有效的治疗方法之一,通常被认为是安全的。然而,一些报道提到,多次ECT会话可引起脑电图(EEG)异常和癫痫发作,ECT的严重副作用。我们在多次ECT会议后经历了脑电图异常的情况,并旨在分享我们对安全进行ECT的见解。
    我们介绍了一名73岁女性被诊断患有重度抑郁症的病例。她定期接受ECT治疗以缓解精神症状。然而,经过80多次会议,观察到以前未被发现的EEG异常。由于患者没有临床癫痫发作,我们能够在不使用抗癫痫药物的情况下以更长的间隔继续ECT。
    我们的案例表明常规脑电图测试对长期ECT患者的重要性。虽然仔细监测是必要的,对于EEG异常的患者,在不使用抗癫痫药物的情况下继续ECT是允许的。
    UNASSIGNED: Electroconvulsive therapy (ECT) is widely recognized as one of the most effective treatments for various psychiatric disorders and is generally considered safe. However, a few reports have mentioned that multiple ECT sessions could induce electroencephalography (EEG) abnormalities and epileptic seizures, a serious side effect of ECT. We experienced a case with EEG abnormalities after multiple ECT sessions and aimed to share our insights on conducting ECT safely.
    UNASSIGNED: We present the case of a 73-year-old female diagnosed with major depressive disorder. She underwent regular ECT sessions to alleviate her psychiatric symptoms. However, after more than 80 sessions, previously undetected EEG abnormalities were observed. Since the patient did not have clinical seizures, we were able to continue ECT at longer intervals without the use of antiepileptic drugs.
    UNASSIGNED: Our case suggests the importance of routine EEG testing in patients undergoing prolonged ECT. While careful monitoring is necessary, continuing ECT without antiepileptic medication in patients with EEG abnormalities could be permissible.

    特发性癫痫(IE)和不明原因的脑膜脑脊髓炎(MUO)是导致狗癫痫发作的脑部疾病的常见原因。在这项研究中,使用LC-MS/MS和NOx分析仪测量MUO或IE犬的脑脊液(CSF)和血浆中196种脂质代谢物和氮氧化物(NO)的浓度,分别。
    九只临床健康的狗以及11和12只IE和MUO的狗,分别,包括在研究中。
    脂质分析显示CSF和血浆中四种和六种脂质代谢产物的水平变化,分别,群体之间。6-酮-前列腺素(PG)F1α(PGF1α)的水平,20-羧基花生四烯酸(20-羧基-AA),9-羟基十八碳二烯酸,MUO犬的脑脊液中溶血血小板活化因子高。此外,11,12-二羟基二十碳三烯酸的血浆水平,20-羧基-AA,油酰乙醇胺在IE犬中含量高,MUO犬的PGF1α含量较高。在患有MUO或IE的狗中,CSF中NO的产生水平很高,但血浆中NO的产生水平却不高。
    这些变化是否代表中枢神经系统疾病的原因或影响尚不清楚;但是,CSF和血浆中的脂质代谢产物和NO的产生可用作诊断生物标志物,可用于治疗犬的特发性或炎症性癫痫。
    UNASSIGNED: Idiopathic epilepsy (IE) and meningoencephalomyelitis of unknown origin (MUO) are common causes of brain diseases leading to seizures in dogs. In this study, the concentrations of 196 lipid metabolites and nitrogen oxide (NO) production in the cerebrospinal fluid (CSF) and plasma of dogs with MUO or IE were measured using a LC-MS/MS and a NOx analyzer, respectively.
    UNASSIGNED: Nine clinically healthy dogs and 11 and 12 dogs with IE and MUO, respectively, were included in the study.
    UNASSIGNED: Lipid analysis revealed variations in the levels of four and six lipid metabolites in CSF and plasma, respectively, between the groups. The levels of 6-keto-prostaglandin (PG) F1α (PGF1α), 20-carboxy arachidonic acid (20-carboxy-AA), 9-hydroxyoctadecadienoic acid, and lyso-platelet-activating factor were high in the CSF of dogs with MUO. In addition, the plasma levels of 11,12-dihydroxyeicosatrienoic acid, 20-carboxy-AA, and oleoylethanolamide were high in dogs with IE, and those of PGF1α were high in dogs with MUO. NO production levels were high in CSF but not in plasma in dogs with MUO or IE.
    UNASSIGNED: It remains unknown whether these changes represent the cause or effect of diseases of the central nervous system; however, lipid metabolites and NO production in CSF and plasma may be used as diagnostic biomarkers and could be exploited for treating idiopathic or inflammatory epilepsy in dogs.

    癫痫发作可因感染而恶化;然而,它们有时在急性病毒感染后消失或减少,虽然这是罕见的。我们报道了一名患有DNM1脑病的男孩在诺如病毒引起的病毒性胃肠炎后癫痫发作的自发缓解。从两个月大开始,他每天都有阵挛性癫痫发作,并在14个月大时出现癫痫性痉挛;此时他被送进医院。体格检查显示肌张力减退,斜视,舌头突出下垂,和宽间隔的牙齿。尽管脑部磁共振成像并不明显,脑电图显示频繁的枕骨尖峰。入院三天后,病人出现频繁腹泻而不发烧。粪便样本中诺如病毒的快速免疫层析检测呈阳性。腹泻出现后立即出现,癫痫发作消失了。目前,五岁的时候,患者有严重的精神运动发育迟缓;他没有言语表达,无法行走。自10个月大以来,他经历了肌阵挛症的非自愿运动。患者DNA的全外显子组测序显示存在DNM1的杂合从头变体:c.709C>T(p。Arg237Trp)。虽然从我们的病人的研究结果表明,潜在的神经网络异常被改善的免疫机制作为病毒感染的结果,需要进一步的研究来阐明癫痫自发缓解背后的机制.
    Epileptic seizures can be worsened by infections; however, they sometimes disappear or decrease after an acute viral infection, although this is rare. We report the spontaneous remission of epileptic seizures following norovirus-induced viral gastroenteritis in a boy with DNM1 encephalopathy. He had clonic seizures daily from the age of two months and developed epileptic spasms at 14 months of age; he was admitted to the hospital at this time. A physical examination revealed hypotonia, strabismus, tongue protrusion with drooping, and widely spaced teeth. Although brain magnetic resonance imaging was unremarkable, electroencephalography revealed frequent occipital spikes. Three days after admission, the patient developed frequent diarrhea without a fever. A rapid immunochromatographic test of norovirus in a stool sample was positive. Immediately after the appearance of diarrhea, the epileptic seizures disappeared. Currently, at the age of five years, the patient has a profound psychomotor developmental delay; he has no verbal expression and is unable to walk. He has experienced involuntary movements of the myoclonus since 10 months of age. Whole-exome sequencing of the patient\'s DNA revealed the presence of a heterozygous de novo variant of DNM1: c.709C>T (p.Arg237Trp). Although the findings from our patient suggest that underlying neural network abnormalities were ameliorated by immunological mechanisms as a result of the viral infection, further research is needed to clarify the mechanisms behind this spontaneous remission of seizures.

    A 4-year-old male neutered Boston Terrier was presented with status epilepticus. He was diagnosed with idiopathic epilepsy and hospitalized with supportive care. During hospitalization, the patient developed both supraventricular and ventricular arrhythmias as well as focal left ventricular dyskinesis. Cardiac troponin I was significantly increased, which was supportive of myocardial damage. Neurogenic stunned myocardium was suspected, and the patient was treated and responded to esmolol. Follow-up echocardiography demonstrated the resolution of the ventricular dyskinesia. This report describes the clinical presentation, diagnostic findings, treatment, management, and outcome of the first reported case of naturally occurring neurogenic stunned myocardium in a dog. Electrocardiogram monitoring, cardiac troponin I, and echocardiography should be considered in patients presenting with seizure activity, especially when exhibiting cluster seizures or in status epilepticus.

    配景与目标:而急性缺血性脑卒中是老年人群癫痫的主要病因,有关其风险因素的数据一直相互矛盾。因此,本研究的目的是确定急性缺血性卒中后早期和晚期癫痫发作与大脑皮层受累和脑电图改变的关系.材料和方法:在立陶宛健康科学大学医院Kaunas神经内科诊所进行了一项前瞻性队列研究,纳入了376例急性缺血性卒中患者。有关人口统计的数据,临床,放射学,收集了脑电图变化。患者在卒中后随访1年,并评估晚期ES。结果:ES发生率为4.5%,早期ES的发生率为2.7%,晚期ES的发生率为2.4%.早期ES的发生增加了发展晚期ES的可能性。急性大脑皮质损害与ES的发生无相关性,包括早期和晚期ES。然而,发作间癫痫样放电与ES的发生有关,包括早期和晚期ES。
    Background and objectives: while acute ischemic stroke is the leading cause of epilepsy in the elderly population, data about its risk factors have been conflicting. Therefore, the aim of our study is to determine the association of early and late epileptic seizures after acute ischemic stroke with cerebral cortical involvement and electroencephalographic changes. Materials and methods: a prospective cohort study in the Hospital of the Lithuanian University of Health Sciences Kaunas Clinics Department of Neurology was conducted and enrolled 376 acute ischemic stroke patients. Data about the demographical, clinical, radiological, and encephalographic changes was gathered. Patients were followed for 1 year after stroke and assessed for late ES. Results: the incidence of ES was 4.5%, the incidence of early ES was 2.7% and the incidence of late ES was 2.4%. The occurrence of early ES increased the probability of developing late ES. There was no association between acute cerebral cortical damage and the occurrence of ES, including both early and late ES. However, interictal epileptiform discharges were associated with the occurrence of ES, including both early and late ES.
