Stroke is one of the most common and serious neurological complications associated with extracorporeal membrane oxygenation （ECMO） therapy， and close monitoring， early recognition， and timely intervention can reduce the incidence rate of stroke and the mortality rate of patients. Transcranial Doppler （TCD） and transcranial color Doppler ultrasonography （TCCD） have emerged as the preferred modalities for monitoring cerebral blood flow in ECMO patients due to their bedside applicability， ability to provide real-time dynamic assessments， and noninvasive safety. This article summarizes the spectral characteristics of cerebral blood flow in patients undergoing various ECMO modalities and elaborates on the latest research advances and clinical significance of TCD/TCCD in predicting stroke events， monitoring cerebral microembolic signals， reflecting the change in intracranial pressure， confirming brain death， and providing prognostic evaluation.

Objective To investigate the safety and efficacy of remote ischemic conditioning （RIC） in the treatment of patients with acute ischemic stroke undergoing mechanical thrombectomy. Methods This was a single-center randomized parallel-controlled clinical study. A total of 40 patients with anterior circulation large-vessel occlusive ischemic stroke who were admitted to Baoji High-Tech Hospital within 24 hours after onset and underwent emergency mechanical thrombectomy from July 2023 to July 2024 were enrolled and randomly assigned to the experimental group and the control group at a ratio of 1∶1. The patients in the experimental group received standardized RIC treatment （cuff pressure 200 mmHg）， while those in the control group received sham RIC intervention （cuff pressure 60 mmHg）， and the course of treatment was 7 days for both groups. The two groups were compared in terms of baseline information， safety assessment indicators （including hemorrhagic transformation， symptomatic intracranial hemorrhage， and adverse events）， and efficacy evaluation indicators [including NIHSS score， Barthel index， and mRS score after 7 days of treatment， as well as the proportion of patients with good prognosis （an mRS score of 0-2） and excellent prognosis （an mRS score of 0-1） at follow-up on day 90]. Results A total of 39 patients were finally included in the analysis， with 19 in the experimental group and 20 in the control group. At follow-up on day 90， 3 patients were lost to follow-up， and 18 patients in each group were included in the analysis. There were no significant differences between the two groups in all baseline data （P0.05） except sex （P=0.048）. The safety analysis showed that during hospitalization， there were no deaths in either group， and there were no significant differences in hemorrhagic transformation， symptomatic intracranial hemorrhage， and adverse events between the two groups （P0.05）. One patient in the control group and 2 patients in the experimental group died at follow-up on day 90， with no significant difference between the two groups（P0.999）. The efficacy analysis showed that after 7 days of treatment， there were no significant differences in NIHSS score， Barthel index， and mRS score between the two groups （P0.05）. At follow-up on day 90 after surgery， 10 patients in the experimental group and 9 patients in the control group had a good prognosis （55.6% vs 50.0%， P0.99）， and 10 patients in the experimental group and 6 patients in the control group had an excellent prognosis （55.6% vs 33.3%， P=0.315）. Conclusion RIC has good safety and efficacy in the treatment of patients with acute ischemic stroke after mechanical thrombectomy， with a tendency to improve 90-day functional prognosis.

Objective To investigate the practical efficacy of precise pulmonary rehabilitation strategy based on lung ultrasound（LUS） in patients with stroke-associated pneumonia （SAP）. Methods A total of 86 SAP patients who attended Xiangtan Central Hospital from January 2023 to January 2025 were enrolled and randomly divided into control group and experimental group， with 43 patients in each group. The patients in the control group received conventional SAP rehabilitation regimen， while those in the experimental group received LUS-based precise pulmonary rehabilitation strategy； the course of intervention was 14 days for both groups. The two groups were compared in terms of pulmonary function， pulmonary infection， inflammatory factors， and quality of life before intervention and after 7 and 14 days of intervention， and adverse reactions were recorded for both groups. Results Significant time， group， and interaction effects were observed in pulmonary function between the two groups， indicating that the experimental group had a significantly better improvement in pulmonary function than the control group， which became more significant over time （P0.001）. Compared with the control group， the experimental group had significantly lower rate of pulmonary infection and levels of inflammatory factors （P0.001）， a significantly higher quality of life （P0.001）， and a significantly lower overall incidence rate of adverse reactions （P0.05）. Conclusion For patients with SAP， the precise pulmonary rehabilitation strategy based on LUS can improve lung function and inflammatory indicators， alleviate pulmonary infection， enhance quality of life， and reduce the risk of adverse reactions. Therefore， it holds promise for clinical application.

Objective To investigate the hemodynamic features of left innominate vein （LIV） compression and their association with clinical manifestations， and to assess the diagnostic value of ultrasound. Methods A total of 32 patients with LIV compression and 67 healthy controls （HCs） were enrolled， and according to the symmetry of the diameters of bilateral transverse sinuses， sigmoid sinuses， and internal jugular veins （IJV）， the HCs were divided into symmetric group with 32 individuals and asymmetric group with 35 individuals. All subjects underwent CTV/MRV and ultrasound examination to measure the diameter， velocity， and flow volume of IJV and vertebral vein， and the differences between groups were analyzed. The receiver operating characteristic （ROC） curve was plotted to assess diagnostic efficacy. Results The patients with LIV compression mainly had the neurological symptoms such as cerebral tinnitus， dizziness， and tinnitus. Compared with the HCs， the patients with LIV compression had a significantly lower total flow volume of IJV and vertebral vein on the ipsilateral side [（406.42±177.05）ml/min vs （742.55±276.41）ml/min， P0.001）]， and the parameters of the ipsilateral side were lower than those of the contralateral side. There was no significant difference in the flow volume of IJV between the contralateral side of patients with LIV compression and the dominant side of the HCs in the asymmetric group. Total flow volume had an area under the ROC curve of 0.849 in predicting LIV compression， with a sensitivity of 77.60%， a specificity of 78.10%， and a cut-off value of 525.73 ml/min. Conclusion This study systematically reveals the blood flow characteristics of the bilateral IJV-vertebral vein system in patients with LIV compression，i.e.，LIV compression leads to a reduction in flow on the ipsilateral side and a compensatory increase on the contralateral side，and the asymmetry of bilateral blood flow may be the cause of the symptoms such as cerebral tinnitus and tinnitus.Ultrasound can be used to measure the total flow volume of IJV and vertebral vein， and it can effectively identify this disease and thus has a good value in screening.

Objective To systematically evaluate the efficacy and safety of Xingnaojing Injection （XNJ） in the treatment of post-stroke disorders of consciousness （PSDOC）. Methods PubMed， Embase， the Cochrane Library， Web of Science， VIP， CNKI， Wanfang Data， and SinoMed were searched for related randomized controlled trials （RCT） published up to July 2025. RevMan 5.4 and Stata 16.0 were used for data extraction and analysis. Results A total of 48 RCT were included， with 4 570 patients in total. The RCT included had relatively low overall risk of bias. The meta-analysis showed that compared with conventional treatment alone， XNJ combined with conventional treatment significantly improved the Glasgow Coma Scale （GCS） score of patients with PSDOC （mean difference=2.62， 95% confidence interval： 2.37-2.86， I²=66%， P0.000 01）. The subgroup analyses showed that XNJ administered at three dosages （20 ml， 30 ml， 40 ml） and for different treatment durations （1 week， 2 weeks， 4 weeks） could effectively improve the GCS score of patients， and it also showed efficacy in patients with hemorrhagic/ischemic stroke and disorders of consciousness. Nine RCT reported the adverse reactions including nausea， rash， and mild dizziness during the trial， which were resolved after the infusion rate was slowed down. Conclusion XNJ is a safe and effective therapy for improving consciousness in patients with PSDOC.

Acute cerebral infarction predominantly occurs in middle-aged and elderly individuals with multiple underlying diseases， and it is often accompanied by atherosclerosis or heart diseases. It has a low incidence rate in children and adolescents， who tend to have atypical symptoms in the early stage， leading to misdiagnosis or missed diagnosis. With the continuous development of imaging technology， the diagnosis of cerebral infarction has become more precise， which helps to further clarify the etiology of cerebral infarction and identify an increasing number of patients with different subtypes of cerebral infarction in clinical practice. This article reports a rare case of a pediatric patient with acute cerebral infarction caused by primary central nervous system vasculitis， which led to neurological dysfunction， in order to improve the awareness of cerebral infarction in children among clinicians.

Objective To investigate the research hotspots， development trends， and potential challenges in the field of stroke and exosomes based on bibliometric and visual analyses， and to provide scientific evidence for basic research and clinical translation. Methods The Web of Science database was used to obtain related articles published up to 2024， and CiteSpace and other tools were used to perform visual analyses from various aspects such as publication trends， collaboration networks， co-occurrence and clustering of keywords， and literature burst analysis. Results A total of 1 153 articles were included. The analysis showed an overall increasing trend in the number of publications per year. The institution with the highest number of publications was Henry Ford Health System， the author with the highest number of publications was Professor Chopp， and the journal with the highest number of articles Int J Mol Sci. High-frequency keywords included "extracellular vesicles" "ischemic stroke" and "stroke"， forming 12 research clusters， with neural repair and barrier protection as the key research directions. Conclusion The research on stroke and exosomes has been increasing year by year， with rapid development in recent years and the formation of an interdisciplinary pattern. Future studies should focus on the molecular mechanisms mediated by exosomes and their clinical application in stroke treatment， so as to promote the development of precision medicine and provide new therapeutic approaches.

Occipital lobe epilepsy （OLE） accounts for 5%-10% of all focal epilepsy cases. Ictal clinical symptoms mainly include visual and ocular movements， with common and specific elementary visual hallucinations. Electroencephalography has certain limitations， and a well-localized unifocal rhythmic ictal discharge during seizure is infrequent on ictal EEG. Detailed preoperative evaluation， especially the evaluation of symptoms and intracranial EEG monitoring， can help to obtain good outcomes after surgical treatment.

This study summarizes the prognosis of epilepsy and related influencing factors in patients with different conditions of epilepsy （after first seizure， refractory epilepsy， and after surgical treatment）. The risk of recurrence was 40%-50% after the first unprovoked seizure， with the risk factors including childhood， history of brain injury， electroencephalographic abnormalities， abnormal brain imaging， and nocturnal seizures. Although immediate medication after the first seizure can reduce the risk of short-term recurrence， there was no significant difference in long-term （over 3 years） seizure-free rate between the delayed treatment （till the second seizure） group and the immediate treatment group. About one-third of patients may progress to intractable epilepsy and have a poor prognosis after anti-seizure medication therapy. Surgical treatment is currently an important treatment regimen to improve the prognosis of patients with intractable epilepsy， and it can significantly improve the prognosis of such patients， with a particularly notable effect in pediatric patients. Preoperative assessment techniques， such as structural connectivity analysis based on diffusion MRI， machine learning models incorporating clinical variables， and computational models based on interictal EEG， can help to predict the optimal resection site， thereby improving the postoperative outcomes of patients. Finally， the integration of big data and omics technology is expected to achieve precise and individualized prognosis prediction and clinical decision-making， promoting the precise long-term management of epilepsy and improving the prognosis of patients.

Post-stroke epilepsy （PSE） is one of the most common complications of stroke and represents a leading cause of secondary epilepsy in adults. Its development follows a well-defined temporal sequence， progressing through stroke onset， latent phase remodeling， and eventual seizure manifestation. PSE is classified into early- and late-onset types based on the timing of seizures. The former is associated with acute injury， while the latter involves chronic reorganization of neural networks. During the latent phase， the brain exhibits pathological changes such as disrupted synaptic plasticity， inflammatory activation， oxidative stress accumulation， and blood-brain barrier disruption， offering a critical window for therapeutic intervention. However， conventional antiseizure medications， which primarily inhibit abnormal neuronal discharges， are insufficient to reverse the underlying pathogenesis and show limited preventive efficacy. Against this backdrop， the concept of disease-modifying treatment （DMT） has gained traction. DMT underscores mechanistic， targeted， and early-stage interventions that prioritize core processes such as inflammation， synaptic remodeling， ferroptosis， and miRNA regulation. Due to its predictability and ease of modeling， PSE serves as an ideal platform for DMT research. Emerging strategies encompass small-molecule drugs， stem cell transplantation， epigenetic modulation， and neuromodulation， some of which have shown promising results in animal models. This review systematically summarizes the pathogenesis of PSE and recent advances in DMT approaches， providing a theoretical foundation and practical guidance for clinical interventions.

Temporal lobe epilepsy is the most common type of focal medically intractable epilepsy. Seizures with involvement of the basal temporal region are extremely rare， and there is still a lack of understanding of their characteristics. The basal temporal region is divided into the olfactory cortex （including the perirhinal cortex and the entorhinal cortex）， the parahippocampal gyrus， and the fusiform gyrus. The ictal symptoms of basal temporal lobe epilepsy include naming dysfunction， comprehension deficit， spontaneous speech， vocal automatism， and dé jà vu. Anterior temporal lobectomy is recommended due to extensive epileptogenic areas.

Epilepsy is a chronic neurological disease characterized by abnormal synchronous discharges of brain neurons. The mutation of GRIN1， a key gene encoding the essential GluN1 subunit of N-methyl-D-aspartate （NMDA） receptors， is closely associated with the pathogenesis and progression of epilepsy. This review summarizes research advances in GRIN1 mutation-related epilepsy， with a focus on its molecular mechanisms， clinical phenotypes， factors influencing phenotypic heterogeneity， and treatment strategies. In terms of molecular mechanisms， GRIN1 mutations affect NMDA receptor function through gain-of-function and loss-of-function mechanisms. Clinical phenotypes show significant heterogeneity， including seizure types， age of onset， and comorbid neurodevelopmental disorders. This heterogeneity may be related to the domain where the mutation is located， the mutation type， and the degree of impact on receptor function. Regarding treatment， gain-of-function mutations can be managed with NMDA receptor antagonists， while loss-of-function mutations may be treated with positive allosteric modulators. The ketogenic diet has also demonstrated potential therapeutic effects. This review aims to provide references for basic research and clinical translation in GRIN1 mutation-related epilepsy， and to promote the development of precision diagnosis and treatment.

Objective To investigate the influence of comorbidities on the prognosis of patients with status epilepticus， to develop Improved Comorbidity Burden Index （ICBI） based on Comorbidity Burden Index （CBI）， and to analyze the practicality of ICBI in assessing nonconvulsive status epilepticus in western China.Methods A total of 396 patients with status epilepticus who were treated in Department of Neurology， Intensive Care Unit， and Emergency Department， West China Hospital， Sichuan University， from December 2016 to December 2022 were enrolled， and all patients met the latest diagnostic criteria for status epilepticus issued by the International League Against Epilepsy （2015 edition）. SPSS 22.0 was used to perform a statistical analysis， and a Logistic regression analysis was used to investigate the influencing factors for in-hospital death and poor prognosis （with a Glasgow Outcome Scale score of 1-3）. CBI score was modified into ICBI score， with the addition of three comorbidities （immune system disorder， thyroid dysfunction， and hypoproteinemia） and consolidation of overlapping items， and the total score was calculated with each comorbidity contributing 1 score. The MedCalc-generated receiver operating characteristic （ROC） curve was used to analyze predictive value， and the area under the ROC curve （AUC） was used to reflect the diagnostic value of ICBI scale.Results Among the 396 patients with status epilepticus included in the study， 43 （10.9%） died in hospital and 114 （28.8%） had a poor prognosis. Digestive system diseases， respiratory system diseases， kidney and urinary system diseases， electrolyte/acid-base imbalance， infection， and immune system disorders were risk factors for in-hospital death of patients with status epilepticus. Digestive system diseases， respiratory system diseases， kidney and urinary system diseases， electrolyte/acid-base imbalance， hypoglycemia/hyperglycemia， infection， coagulation and blood disorders， nervous system disease， cardiovascular diseases， musculoskeletal disorders， and immune system disorders were risk factors for poor prognosis in patients with status epilepticus. The ROC curve analysis showed that ICBI>3 had an AUC of 0.914 in predicting in-hospital death， with a specificity of 71.37% and a sensitivity of 97.67% （P<0.000 1）， and ICBI>3 had an AUC of 0.882 in predicting poor prognosis， with a specificity of 81.56% and a sensitivity of 79.82% （P<0.000 1）. There were 327 patients with convulsive status epilepticus， among whom 41 patients died， and ICBI>3 had an AUC of 0.915 in predicting in-hospital death （P<0.000 1）. There were 100 patients with a poor prognosis， and ICBI>3 had an AUC of 0.867 in predicting poor prognosis （P<0.000 1）.Conclusion The in-hospital mortality rate is 10.9% in patients with status epilepticus in Sichuan， China， and ICBI>3 has a certain value in predicting in-hospital death and poor prognosis in patients with status epilepticus. There is no significant difference in ICBI score between convulsive status epilepticus and nonconvulsive status epilepticus.

Nonconvulsive status epilepticus （NCSE） is a state of persistent epileptic seizure characterized by disturbance of consciousness or major neurological deficits， without obvious limb convulsions. Due to a lack of obvious clinical manifestations and the potential risk of neurological damage， current research focuses on rapid identification， accurate classification， and optimization of treatment strategies. Since there is a lack of obvious motor symptoms in NCSE， it is difficult for clinicians to quickly identify the disease through traditional signs， which poses great challenges to diagnosis， and underdiagnosis may lead to delayed treatment and poor prognosis. This article systematically reviews the epidemiological characteristics， clinical manifestations， and key diagnostic points of NCSE and discusses existing treatment regimens and prognosis， in order to provide a reference for clinical practice.

Objective To summarize the clinical features of epileptic patients with visual hallucination as the main ictal symptom.Methods The epileptic patients with visual hallucination as the main feature who were admitted to Peking University First Hospital were enrolled， and clinical data were collected for descriptive analysis.Results Five epileptic patients were enrolled， among whom there were two patients with simple visual hallucination and three patients with complex visual hallucinations. Three patients were found to have intracranial space-occupying lesions， one with a left occipital vascular malformation， one located subcortically in the right posterior temporal region， and one in the anterior temporal area.Conclusion Epileptic seizures with visual symptoms are relatively uncommon in clinical practice， and this study reports five epileptic patients with the main symptom of classic visual hallucination， in order to improve the diagnosis and treatment of such diseases among clinicians.

Objective Idiopathic rolandic epilepsy syndrome （IRES） is the most common epilepsy syndrome in childhood， and its lesion site remains undetermined. This article aims to investigate the source of epileptiform discharges in IRES using magnetoencephalography （MEG）.Methods A total of 70 patients with IRES were enrolled in this prospective MEG-based study， among whom there were 53 children with benign epilepsy of childhood with centrotemporal spikes （BECTS）， 12 children with atypical benign partial epilepsy （ABPE）， 3 children with Landau-Kleffner syndrome （LKS）， and 2 children with epileptic encephalopathy with continuous spike-and-waves during slow-wave sleep （CSWS）. Epileptiform discharges were collected independently from each patient 10 times， and an MEG source analysis was performed. Standardized low-resolution brain electromagnetic tomography was used to perform source localization of the distributed source model. The spike source density was quantified into amplitude， and source location was determined according to the Desikan-Killiany atlas. The association between the distribution of spike source in brain and clinical manifestations was analyzed.Results In IRES， there were significant differences in the source locations of epilepsy discharge between BECTS， ABPE， LKS， and CSWS. The current source density of CSWS was stronger in the frontal lobe， the temporal lobe， and the anterior cingulate gyrus， while that of ABPE was stronger in the frontal lobe， and that of BECTS and LKS were stronger in the temporal lobe. The more severe phenotype of epilepsy， such as generalized tonic-clonic seizure， was associated with a stronger current source density in the brain， which was consistent with electroencephalography manifestations.Conclusion This study identifies different sources of epileptiform discharges in IRES. The density distribution of these spike sources may help to explain the discharge， cognitive， and neuropsychological characteristics in different subtypes of IRES.

Migraine is the most common neurological disorder with the highest disease burden， while the current outpatient diagnosis and treatment model cannot meet the requirements for reducing the disease burden of migraine， and it is necessary to reexamine its management from a patient-centered perspective. It should be recognized that the course of migraine is a dynamic process，and some clinical manifestations that are not included in the diagnostic criteria are meaningful for diagnosis.Several risk factors for the chronicity of migraine have been identified.In addition， various comorbidities can also affect diagnosis and treatment，and it is still unable to reliably predict the treatment response of migraine.Therefore， the management of migraine requires continuous revision of diagnosis and “trial-and-error” treatment.

Migraine is a complex chronic central nervous system disorder with a gradually increasing prevalence rate around the world， causing a significant healthcare burden.Recent studies have shown that gut microbiota plays a crucial role in the pathophysiological process of migraine through the bidirectional communication network of the gut-brain axis. This article systematically reviews the association and mechanisms between the gut microbiota-gut-brain axis and migraine， in order to provide new perspectives for in-depth research and clinical prevention and treatment of migraine.

Short-lasting unilateral neuralgiform headache attacks （SUNHA） are a rare type of disabling primary headache within the category of trigeminal autonomic cephalalgias （TACs）， and it has two subtypes of SUNCT （with conjunctival injection and tearing） and SUNA （with other autonomic features）. SUNHA is characterized by severe unilateral （often V1） stabbing/shock-like pain （lasting for 1-600 s）， high frequency （2‒600 attacks a day）， and prominent ipsilateral cranial autonomic symptoms （such as conjunctival injection，tearing， and nasal obstruction）. Trigger factors are observed in 86% of patients. The diagnosis of SUNHA should meet the ICHD-3 criteria （≥20 attacks）， and brain MRI （especially for the pituitary gland/posterior cranial fossa） should be performed to exclude secondary causes （such as neurovascular conflict and pituitary tumor）. Lamotrigine is used as first-line prophylaxis， while lidocaine aids acute relief in the transitional phase； occipital nerve stimulation， deep brain stimulation， or microvascular decompression can be used for refractory cases. It is of great importance to enhance awareness， achieve precise differentiation（from trigeminal neuralgia or other types of TACs）， and provide individualized treatment.

Objective Sentinel headache（SH） refers to new-onset headache or existing headache with altered characteristics that occurs within seven days before stroke in patients， and this study aims to investigate the incidence rate and clinical features of SH in stroke patients and its association with prognosis. Methods A total of 145 stroke patients who were admitted to Department of Neurology， The First Affiliated Hospital of Xi’an Jiaotong University， from August 2022 to April 2023 were enrolled based on inclusion/exclusion criteria， and general information was collected. According to the presence or absence of SH， they were divided into headache and control group. The features of SH were summarized， and follow-up was performed after 1 year to analyze the association between SH and prognosis. Results Among the 145 patients with stroke，30（20.7%） developed SH， with the subtypes of intracerebral hemorrhage（9 patients， 25.7%）， cerebral infarction （15 patients，18.9%）， transient ischemic attack（3 patients，14.3%）， and subarachnoid hemorrhage （3 patients， 30.0%）. Conclusion SH may occur in all stroke patients， with a prevalence rate of 20.7%. The manifestations of SH include migraine-like headache， tension-type headache， and cluster-like headache. The results of this study do not establish an association between SH and 1-year prognosis in stroke patients，and further studies are needed in the future.
