Objective

Depressive symptoms were a prevalent comorbidity among patients with epilepsy, significantly impacting their quality of life and treatment outcomes. This study aims to investigate the prevalence and clinical correlates of depressive symptoms in Chinese patients with epilepsy.

Methods

A descriptive cross-sectional study was conducted at the Department of Neurosurgery, General Hospital of Northern Theater Command, from January 2018 to June 2023. Patients diagnosed with epilepsy aged 16 years or older were included, excluding those with severe illnesses, substance abuse disorders, or severe cognitive impairments. Demographic and epilepsy-related information was collected using a standardized clinical data collection form. Depressive symptoms were assessed using the Beck Depression Inventory-II (BDI-II). Statistical analyses were performed using SPSS version 27.0.

Results

The study included 513 patients with epilepsy, with a mean age of 37.48 years (SD= 15.09). Among these, 65.9 % were male, and 62.6 % were aged 40 years or older. The majority of patients were single (50.9 %) and had formal education (57.1 %). The mean age of epilepsy onset was 21.96 years (SD = 12.83), and the mean duration of illness was 11.02 years (SD= 13.64). Generalized tonic-clonic seizures were the most common type (62.0 %), and 32.7 % of patients experienced very frequent seizures. Polytherapy was used by 63.5 % of patients. Depressive symptoms were present in 137 patients, representing a prevalence of 26.7 % (95 % CI: 20.51–31.89). The severity of depressive symptoms was categorized as mild in 62.0 %, mild to moderate in 18.2 %, moderate in 10.2 %, and severe in 9.5 %. The prevalence of depressive symptoms was higher among females, separated/widowed individuals, those with lower educational attainment, and unemployed patients. Significant associations were found between depressive symptoms and seizure frequency, duration of seizures, and polytherapy. Multivariate analysis identified seizure frequency, duration of seizures, and polytherapy as independent predictors of depressive symptoms.

Conclusions

Depressive symptoms were highly prevalent among Chinese patients with epilepsy, with significant associations found between depressive symptoms and several sociodemographic and clinical characteristics. Routine screening for depressive symptoms and tailored interventions are crucial for improving the quality of life and treatment outcomes in this population. Future research should focus on longitudinal studies to explore causal relationships and develop targeted interventions.
目的:抑郁症状是癫痫患者常见的合并症,显著影响癫痫患者的生活质量和治疗效果。本研究旨在探讨中国癫痫患者抑郁症状的患病率及临床相关因素。方法于2018年1月至2023年6月在北方战区总医院神经外科进行描述性横断面研究。16岁及以上的癫痫患者被纳入研究,但不包括那些患有严重疾病、药物滥用障碍或严重认知障碍的患者。使用标准化的临床数据收集表收集人口统计学和癫痫相关信息。使用贝克抑郁量表- ii (BDI-II)评估抑郁症状。采用SPSS 27.0进行统计分析。结果纳入513例癫痫患者,平均年龄37.48岁(SD= 15.09)。其中男性占65.9% %,年龄在40岁以上的占62.6 %。大多数患者为单身(50.9 %)和受过正规教育(57.1% %)。平均发病年龄21.96岁(SD= 12.83),平均发病时间11.02岁(SD= 13.64)。全身性强直-阵挛性发作是最常见的类型(62.0 %),32.7% %的患者经历过非常频繁的发作。63.5% %的患者采用综合治疗。137例患者出现抑郁症状,患病率为26.7 %(95 % CI: 20.51-31.89)。抑郁症状的严重程度分为轻度(62.0 %)、轻度至中度(18.2% %)、中度(10. %)和重度(9.5% %)。抑郁症状的患病率在女性、分居/丧偶个体、受教育程度较低的个体和失业患者中较高。发现抑郁症状与发作频率、发作持续时间和多种治疗之间存在显著关联。多变量分析确定癫痫发作频率、癫痫发作持续时间和多种治疗是抑郁症状的独立预测因子。结论抑郁症状在中国癫痫患者中非常普遍,抑郁症状与一些社会人口学和临床特征有显著相关性。常规抑郁症状筛查和量身定制的干预措施对于改善这一人群的生活质量和治疗效果至关重要。未来的研究应侧重于纵向研究,以探索因果关系并制定有针对性的干预措施。

Objectives

Epilepsy is the most common serious neurological disorder in children; however, previous long-term studies are often limited by small sample sizes or methodological variability. This study aimed to assess the epidemiology, seizure outcomes, and prognostic factors of childhood-onset epilepsy over > 10 years of follow-up at a single tertiary center.

Methods

We retrospectively analyzed the medical records of 4248 patients diagnosed with epilepsy before age 19 between 1995 and 2017 at Asan Medical Center Children’s Hospital. All patients underwent at least one electroencephalogram (EEG) and received anti-seizure medications (ASMs) for > 2 years.

Results

During a mean follow-up of 11.0 years, 43 patients (1.0 %) died. The median age at seizure onset was 7.2 years. Etiologies included unknown (52.5 %), structural (29.3 %), genetic/metabolic (23.4 %), and infectious/autoimmune (4.5 %). Focal epilepsy was the most common (63.4 %). Neurocognitive and psychological comorbidities were observed in 32.7 % and 20.6 % of patients, respectively. Seizure freedom for ≥ 2 years was achieved in 81.2 %, and terminal remission in 63.1 %. However, relapse occurred in 38.0 %, and 28.6 % developed intractable epilepsy. Prognostic factors included status epilepticus, intellectual disability, pretreatment seizure frequency, etiology, epilepsy syndromes, and EEG abnormalities.

Conclusions

This study reaffirms known risk factors while providing comprehensive insights into seizure trajectories, relapse patterns, and treatment responses in a large cohort. It highlights the clinical relevance of the 2-year seizure-free definition and underscores the need for early interventions in high-risk subgroups. Despite diagnostic advances, several cases remain etiologically unresolved, reinforcing the importance of expanding access to molecular and imaging tools in pediatric epilepsy care.
目的:癫痫是儿童最常见的严重神经系统疾病;然而,以往的长期研究往往受到样本量小或方法可变性的限制。本研究旨在评估儿童癫痫的流行病学、癫痫发作结局和预后因素,随访时间为 10年。方法回顾性分析1995 ~ 2017年在峨山医疗中心儿童医院诊断为19岁以下癫痫的4248例患者的病历。所有患者至少接受一次脑电图(EEG)检查,并接受抗癫痫药物治疗 2年。结果平均随访11.0年,死亡43例(1.0 %)。癫痫发作的中位年龄为7.2岁。病因包括未知(52.5 %)、结构(29.3 %)、遗传/代谢(23.4 %)和感染/自身免疫(4.5 %)。局灶性癫痫最常见(63.4 %)。神经认知和心理合并症分别为32.7% %和20.6% %。≥ 2年癫痫发作自由率为81.2 %,最终缓解率为63.1 %。然而,复发发生率为38.0% %,并发难治性癫痫28.6% %。预后因素包括癫痫持续状态、智力残疾、癫痫发作前频率、病因、癫痫综合征和脑电图异常。结论:本研究重申了已知的危险因素,同时在一个大队列中对癫痫发作轨迹、复发模式和治疗反应提供了全面的见解。它强调了2年无癫痫发作定义的临床相关性,并强调了对高危亚组进行早期干预的必要性。尽管在诊断方面取得了进展,但仍有一些病例病因不明,这加强了在儿童癫痫护理中扩大分子和成像工具可及性的重要性。

Background

Epilepsy affects approximately 6.4 per 1000 individuals worldwide. Despite advances in antiseizure medications (ASMs), nearly one-third of patients remain refractory to treatment, meeting criteria for drug-resistant epilepsy (DRE). This meta-analysis evaluated the performance of machine learning (ML) models in predicting therapeutic response in DRE based on ILAE-defined outcomes.

Methods

A systematic review and meta-analysis were conducted in accordance with PRISMA-DTA guidelines. Studies applying ML algorithms to predict treatment response in DRE were included. Eligible designs comprised retrospective or prospective observational studies. Outcomes included seizure remission (ILAE Class 1), ≥ 50 % reduction in seizure frequency, treatment failure, and diagnostic accuracy metrics. A bivariate random-effects model was used to pool sensitivity, specificity, and diagnostic odds ratio (DOR). Heterogeneity was assessed (I², χ²), and subgroup and meta-regression analyses were performed. Likelihood ratios, area under the curve (AUC), and Bayesian post-test probabilities were estimated. Publication bias was evaluated with Deeks’ test.

Results

Eight studies (n = 1887) met inclusion criteria (Kappa=0.98). Pooled sensitivity and specificity were both 0.84 (95 % CI: 0.76–0.89 and 0.77–0.89, respectively), with an AUC of 0.91. DOR was 27; LR+ , 5.2; LR−, 0.19. Heterogeneity was high (χ²=22.7; p < 0.001). Sensitivity was lower in prospective studies, prognostic models, and ASMs users, and higher with long-term follow-up. Meta-regression identified model type, study design, ASM exposure, and sample adequacy as key moderators.

Conclusion

ML models demonstrate high diagnostic accuracy in predicting therapeutic response in DRE. Findings support their potential clinical utility, provided external validation and methodological standardisation.

Blood-brain barrier impairment as an early marker of neurodegeneration in late-onset epilepsy of unknown origin 血脑屏障损伤是不明原因迟发性癫痫神经退行性变的早期标志
IF 2 4区 医学 Q3 CLINICAL NEUROLOGY Pub Date : 2025-11-01 Epub Date: 2025-06-24 DOI: 10.1016/j.eplepsyres.2025.107614

Purpose

Blood-brain barrier (BBB) plays a crucial role in maintaining brain health, and its dysfunction during the early stages of neurodegeneration may contribute to neuropathological processes. Patients with late-onset epilepsy with unknown etiology (LOEU) can present early signs of neurodegeneration and convert to an overt neurodegenerative disease longitudinally. This study analyzed cerebrospinal-fluid (CSF)/serum albumin ratio (Qalb), as a marker of BBB integrity, and assessed biomarkers of neurodegeneration in patients with LOEU compared to age- and sex-matched controls.

Methods

Patients diagnosed with LOEU were compared to a sex- and age-matched control group. All participants underwent a neurological visit, cognitive evaluation to exclude cognitive impairment, and a lumbar puncture for CSF biomarker analysis [β-Amyloid42 (Aβ42); total-Tau (t-Tau); phosphorylated-Tau at threonine 181 (p-Tau181); Qalb]. Lumbar puncture was performed within 2 months after epilepsy diagnosis, and at least 3 weeks after the last seizure.

Results

Twenty-eight LOEU patients (53.6 % female, mean age 68.79 ± 7.83 y) and twenty-five controls (52.0 % female, mean age 65.64 ± 8.10 y) were included. LOEU patients showed significantly higher Qalb values (p = 0.003), lower Aβ₄₂ CSF levels (p = 0.030), and higher t-Tau/Aβ₄₂ (p = 0.030) and p-Tau181/Aβ₄₂ ratios (p = 0.030) than controls. Qalb values did not significantly differ between patients with and without pathological AD biomarker profile.

Conclusions

LOEU patients show BBB dysfunction and early changes in CSF biomarker ratios pointing to AD pathology. Qalb increase seems to be unrelated to the pathological changes in CSF AD biomarkers. Future studies should be performed to better understand the neuropathological basis of LOEU and the risk for patients to develop a neurodegenerative disorder.
目的血脑屏障(BBB)在维持大脑健康中起着至关重要的作用,其在神经退行性疾病早期的功能障碍可能导致神经病理过程。病因不明的迟发性癫痫(LOEU)患者可以表现出神经退行性疾病的早期症状,并在纵向上转化为明显的神经退行性疾病。该研究分析了脑脊液(CSF)/血清白蛋白比率(Qalb),作为血脑屏障完整性的标志,并与年龄和性别匹配的对照组相比,评估了LOEU患者神经退行性变的生物标志物。方法将诊断为LOEU的患者与性别和年龄匹配的对照组进行比较。所有参与者都进行了神经学检查,认知评估以排除认知障碍,并进行腰椎穿刺以进行脑脊液生物标志物分析[β-淀粉样蛋白42 (a β42);total-Tau (t-Tau);苏氨酸181位点磷酸化tau蛋白(p-Tau181);Qalb]。在癫痫诊断后2个月内,至少在最后一次癫痫发作后3周进行腰椎穿刺。结果纳入LOEU患者28例(女性53.6 %,平均年龄68.79 ± 7.83 y),对照组25例(女性52.0 %,平均年龄65.64 ± 8.10 y)。LOEU患者Qalb值显著高于对照组(p = 0.003),Aβ₄2 CSF水平显著低于对照组(p = 0.030),t-Tau/Aβ₄2 (p = 0.030)和p- tau181 /Aβ₄2比率显著高于对照组(p = 0.030)。Qalb值在有和没有病理性AD生物标志物谱的患者之间没有显著差异。结论eu患者血脑屏障功能障碍,脑脊液生物标志物比值早期变化提示AD病理。Qalb升高似乎与脑脊液AD生物标志物的病理改变无关。未来的研究应该更好地了解LOEU的神经病理学基础和患者发展为神经退行性疾病的风险。

Our primary objective was to estimate the association between post-stroke statin use and post-stroke epilepsy (PSE) and assess whether sex modifies this association. Our second objective was to assess whether statin characteristics and other risk factors affect the risk of PSE overall and within groups defined by sex. We conducted a population-based nested case-control study, using linked health administrative data and including residents older than 65 of Ontario, Canada treated for an ischemic stroke between April 1, 2007, and March 31, 2017. Patients who developed epilepsy were matched with up to 10 controls on age, sex, and month. Multivariable conditional logistic regression models were used to estimate the adjusted odds ratios for PSE associated with post-stroke statin use and potential risk factors. We included 1009 patients with epilepsy and 6522 matched controls. Statin use was not associated with the risk of epilepsy in the entire cohort or in the sex-stratified analysis (IRR = 1.17; 95 % CI 0.95–1.43), and sex did not significantly modify the association (p-value=0.08). Statin characteristics did not affect the risk of epilepsy in the entire cohort; however, we observed an increased risk of PSE associated with the use of atorvastatin among females in the sex-stratified analyses (IRR = 1.26; 95 % CI 1.02–1.56). Although the risk of epilepsy did not significantly differ between statin users and non-users in the entire cohort or within groups defined by sex, atorvastatin was associated with an increased risk of PSE compared to statin non-users among women and should be further explored.
我们的主要目的是评估卒中后他汀类药物使用与卒中后癫痫(PSE)之间的关系,并评估性别是否会改变这种关系。我们的第二个目标是评估他汀类药物的特征和其他危险因素是否会影响PSE的总体风险,并在按性别定义的人群中影响PSE的风险。我们进行了一项基于人群的巢式病例对照研究,使用相关的健康管理数据,包括2007年4月1日至2017年3月31日期间加拿大安大略省65岁以上的缺血性中风患者。癫痫患者在年龄、性别和月份上与多达10个对照组相匹配。使用多变量条件logistic回归模型来估计卒中后他汀类药物使用和潜在危险因素与PSE相关的校正优势比。我们纳入了1009例癫痫患者和6522例匹配的对照。在整个队列或性别分层分析中,他汀类药物的使用与癫痫的风险无关(IRR = 1.17;95 % CI 0.95-1.43),性别没有显著改变相关性(p值=0.08)。在整个队列中,他汀类药物的特征没有影响癫痫的风险;然而,在性别分层分析中,我们观察到女性使用阿托伐他汀会增加PSE的风险(IRR = 1.26;95 % ci 1.02-1.56)。尽管癫痫的风险在整个队列或按性别定义的组中,他汀类药物使用者和非使用者之间没有显著差异,但在女性中,与非他汀类药物使用者相比,阿托伐他汀与PSE的风险增加有关,应该进一步探讨。

White matter integrity and its correlation to seizures in diffuse glioma 弥漫性胶质瘤中白质完整性及其与癫痫发作的关系
IF 2 4区 医学 Q3 CLINICAL NEUROLOGY Pub Date : 2025-11-01 Epub Date: 2025-07-14 DOI: 10.1016/j.eplepsyres.2025.107627

Introduction

Seizures are one of the most common symptoms in patients with diffuse glioma, occurring in 30–80 % of cases. Although seizure control can be achieved in up to 90 %, seizures remain a significant burden and are hardly predictable. The aim of this analysis was, therefore, to investigate the association between white matter integrity and seizure occurrence in patients with diffuse glioma using diffusion tensor imaging (DTI).

Methods

Patients with first diagnosis of diffuse glioma (WHO-grade 2, 3, 4) who received preoperative DTI sequences for surgical planning were analyzed. Tractography of corpus callosum and cingulum was carried out, extracting mean FA values of the resulting volumes.

Results

50 patients (17 female) were included with a mean age of 59.5 ± 2.2 years. Glioma WHO grade 4 was most common (82 %), followed by grade 3 (10 %) and grade 2 (8 %). Most gliomas were located left temporal (32 %) and bilateral frontal (each hemisphere 16 %). 16 % presented with multifocal glioma. 48 % had suffered seizures prior to surgery, and were thus diagnosed with structural epilepsy. 22 % of all patients presented recurring seizures despite surgery and anti-seizure medication, and 6 % developed new seizures after surgery. After correction for multiple comparisons, increased FA in the left parahippocampal cingulum was significantly associated with preoperative seizures (0.30 ± 0.01 versus 0.27 ± 0.01, pcorr = 0.007), while increased FA in the forceps minor of the corpus callosum correlated with postoperative seizures (0.49 ± 0.01 versus 0.43 ± 0.01, pcorr = 0.014).

Conclusion

Higher preoperative white matter integrity was associated with increased risk for occurrence of seizures in diffuse glioma. Further research is warranted to investigate the relation with tumor pathology.
癫痫发作是弥漫性胶质瘤患者最常见的症状之一,发生率为30 - 80% %。虽然癫痫发作控制可以达到90% %,但癫痫发作仍然是一个重大负担,很难预测。因此,本分析的目的是利用弥散张量成像(DTI)研究弥漫性胶质瘤患者白质完整性与癫痫发作之间的关系。方法对首次诊断为弥漫性胶质瘤(who分级2级、3级、4级)且术前接受DTI序列进行手术计划的患者进行分析。对胼胝体和扣带进行神经束造影,提取所得体积的平均FA值。结果纳入50例患者,其中女性17例,平均年龄59.5 ± 2.2岁。WHO 4级胶质瘤最常见(82% %),其次是3级(10 %)和2级(8 %)。大多数胶质瘤位于左侧颞叶(32 %)和双侧额叶(每个半球16 %)。16% %为多灶性胶质瘤。48% %手术前曾有癫痫发作,因此被诊断为结构性癫痫。22 %的患者在手术和抗癫痫药物治疗后出现复发性癫痫发作,6 %的患者在手术后出现新的癫痫发作。经多次校正比较,左侧海马旁扣带FA增加与术前癫痫发作显著相关(0.30 ± 0.01 vs 0.27 ± 0.01,pcorr = 0.007),胼胝体小钳FA增加与术后癫痫发作相关(0.49 ± 0.01 vs 0.43 ± 0.01,pcorr = 0.014)。结论弥漫性胶质瘤患者术前白质完整性增高与癫痫发作风险增加相关。值得进一步研究其与肿瘤病理的关系。

Seizure outcome and anti-seizure medication use in post-stroke epilepsy: A retrospective cohort study 卒中后癫痫的发作结果和抗发作药物的使用:一项回顾性队列研究
IF 2 4区 医学 Q3 CLINICAL NEUROLOGY Pub Date : 2025-11-01 Epub Date: 2025-06-19 DOI: 10.1016/j.eplepsyres.2025.107616

Background

Most patients with post-stroke epilepsy (PSE) are considered to be well controlled with anti-seizure medications (ASMs). First-generation ASMs with potent enzyme-inducing properties can reduce the efficacy of concomitant medications and were related to increased mortality in PSE.

Objective

To evaluate seizure outcome and patterns of ASM use in patients with PSE.

Methods

We retrospectively reviewed the computerized database and the medical records of all the patients who had their first visit in our adult outpatient epilepsy clinic during a 10-year period (2012–2021), and identified 39 patients with PSE and 382 patients with focal epilepsy without a previous stroke (FEWS).

Results

The study group included 421 patients aged 18–90 years, 220 (52.3 %) men, follow-up duration 3.1 ± 2.9 years. At first observation, patients with PSE had lower rates of daily to monthly seizures (p = 0.023) and higher rates of a single seizure (p = 0.023) compared to patients with FEWS, and 66 % were treated with first-generation ASMs. At last observation, seizure frequency improved in fewer patients with PSE compared to FEWS (p = 0.042), with significant decrease in the rate of daily to monthly seizures in patients with FEWS (p = 0.0001).

Conclusions

Seizure outcome in patients with PSE may be less favorable than previously reported, and many were still treated with ASMs that can adversely affect vascular risk. Further studies are needed to evaluate therapeutic strategies that can improve seizure control and achieve higher rates of seizure freedom in patients with PSE.
大多数脑卒中后癫痫(PSE)患者被认为通过抗癫痫药物(asm)得到了很好的控制。第一代asm具有强大的酶诱导特性,可降低伴随药物的疗效,并与PSE死亡率增加有关。目的评价癫痫发作的预后及ASM在PSE患者中的应用模式。方法回顾性分析我院成人癫痫门诊10年间(2012-2021年)首次就诊患者的计算机数据库和医疗记录,发现39例PSE患者和382例局灶性癫痫患者无卒中史(FEWS)。结果研究组纳入患者421例,年龄18-90岁,男性220例(52.3 %),随访时间3.1 ± 2.9年。在第一次观察中,与FEWS患者相比,PSE患者的每日至每月癫痫发作率较低(p = 0.023),单次癫痫发作率较高(p = 0.023),66% %的患者接受了第一代ASMs治疗。最后观察,与FEWS相比,PSE患者的癫痫发作频率改善较少(p = 0.042),FEWS患者的每日至每月癫痫发作率显著降低(p = 0.0001)。结论:PSE患者的癫痫发作结果可能不如先前报道的那样有利,许多患者仍接受可对血管风险产生不利影响的asm治疗。需要进一步的研究来评估治疗策略,以改善PSE患者的癫痫控制并实现更高的癫痫发作自由率。
