Journal of Apoplexy and Nervous Diseases 2026;43(2):110-113
Objective To investigate the cranial magnetic resonance imaging (MRI) features of patients with hepatolenticular degeneration (also known as Wilson disease,WD) and epilepsy, and to identify the neuroimaging risk factors for seizures in WD patients. Methods A total of 69 WD patients with epilepsy who were hospitalized in Affiliated Hospital of Neurology Institute, Anhui University of Chinese Medicine, from January 2018 to November 2025 were enrolled as study group, while 80 WD patients without seizures, matched for sex and age, during the same period of time were randomly selected as control group. Cranial MRI findings were compared between the two groups. Results There were 69 WD patients (43 male patients and 26 female patients) in the study group, with a mean age of (29.46±8.58) years at the time of attending the hospital, and all these patients had abnormal electroencephalogram (EEG) findings. There were no significant differences between the two groups in age of onset,disease duration, WD subtype, and serum copper. Cranial MRI showed that the putamen was the most common site of brain injury (47 patients, 68.1%), followed by the frontal lobe (40 patients,58.0%) and the parietal lobe (31 patients,44.9%), and there was a significantly higher probability of epilepsy in patients with abnormal lesions in the frontal, temporal, or parietal lobes (P<0.05). Conclusion While the putamen is the most common site of brain injury in WD patients with epilepsy, frontal or temporal lobe injuries are neuroimaging risk factors for seizures in such patients.

BACKGROUND:
To evaluate the efficacy and safety of the first cohort of people in China treated with a responsive neurostimulation system (Epilcure TM , GenLight MedTech, Hangzhou, China) for focal drug-resistant epilepsy in this study.
METHODS:
This multicenter, before-and-after self-controlled study was conducted across 8 centers from March 2022 to June 2023, involving patients with drug-resistant epilepsy who were undergoing responsive neurostimulation (RNS). The study was based on an ongoing multi-center, single-blind, randomized controlled study. Efficacy was assessed through metrics including median seizure count, seizure frequency reduction (SFR), and response rate. Multivariable linear regression analysis was conducted to explore the relationships of basic clinical factors and intracranial electrophysiological characteristics with SFR. The postoperative quality of life, cognitive function, depression, and anxiety were evaluated as well.
RESULTS:
The follow-up period for the 19 participants was 10.7 ± 3.4 months. Seizure counts decreased significantly 6 months after device activation, with median SFR of 48% at the 6th month (M6) and 58% at M12 ( P <0.05). The average response rate after 13 months of treatment was 42%, with 21% ( n = 4) of the participants achieving seizure freedom. Patients who have previously undergone resective surgery appear to achieve better therapeutic outcomes at M11, M12 and M13 ( β <0, P <0.05). No statistically significant differences were observed in patients' scores of quality of life, cognition, depression and anxiety following stimulation when compared to baseline measurements. No serious adverse events related to the devices were observed.
CONCLUSIONS:
The preliminary findings suggest that Epilcure TM exhibits promising therapeutic potential in reducing the frequency of epileptic seizures. However, to further validate its efficacy, larger-scale randomized controlled trials are required.

The zebrafish model has attracted much attention due to its strong reproductive ability, short research cycle, and ease of maintenance. It has always been an important vertebrate model system, often used to carry out human disease research. Its motor behavior features have the advantages of being simpler, more intuitive, and quantifiable. In recent years, it has received widespread attention in the study of traditional Chinese medicine(TCM)for the treatment of sleep disorders, neurodegenerative diseases, fatigue, epilepsy, and other diseases. This paper reviews the characteristics of zebrafish motor behavior and its applications in the pharmacodynamic verification and mechanism research of TCM extracts, active ingredients, and TCM compounds, as well as in active ingredient screening and safety evaluation. The paper also analyzes its advantages and disadvantages, with the aim of improving the breadth and depth of zebrafish and its motor behavior applications in the field of TCM research.

The existing epilepsy seizure detection algorithms have problems such as overfitting and poor generalization ability due to high reliance on manual labeling of electroencephalogram's data and data imbalance between seizure and interictal periods. An unsupervised learning detection method for epileptic seizure that jointed graph attention network (GAT) and Transformer framework (GAT-T) was proposed. In this method, channel correlations were adaptively learned by GAT encoder. Temporal information was captured by one-dimensional convolution decoder. Combining outputs of the two mentioned above, predicted values for electroencephalogram were generated. The collective anomaly score was calculated and the detection threshold was determined. The results demonstrated that GAT-T achieved the average performance exceeding 90% (or 99%) with a 0.25 s (or 2 s) time segment length, which could effectively detect epileptic seizures. Moreover, the channel association probability matrix was expected to assist clinicians in the initial screening of the epileptogenic zone, and ablation experiments also reflected the significance of each module in GAT-T. This study may assist clinicians in making more accurate diagnostic and therapeutic decisions for epilepsy patients.

Current epilepsy prediction methods are not effective in characterizing the multi-domain features of complex long-term electroencephalogram (EEG) data, leading to suboptimal prediction performance. Therefore, this paper proposes a novel multi-scale sparse adaptive convolutional network based on multi-head attention mechanism (MS-SACN-MM) model to effectively characterize the multi-domain features. The model first preprocesses the EEG data, constructs multiple convolutional layers to effectively avoid information overload, and uses a multi-layer perceptron and multi-head attention mechanism to focus the network on critical pre-seizure features. Then, it adopts a focal loss training strategy to alleviate class imbalance and enhance the model's robustness. Experimental results show that on the publicly created dataset (CHB-MIT) by MIT and Boston Children's Hospital, the MS-SACN-MM model achieves a maximum accuracy of 0.999 for seizure prediction 10 ~ 15 minutes in advance. This demonstrates good predictive performance and holds significant importance for early intervention and intelligent clinical management of epilepsy patients.

6.Efficacy and safety of perampanel add-on therapy in children with epilepsy of genetic etiology.
Chinese Journal of Contemporary Pediatrics 2025;27(2):171-175
OBJECTIVES:
To investigate the efficacy and safety of perampanel (PER) add-on therapy in children with epilepsy of genetic etiology.
METHODS:
A retrospective analysis was conducted on the clinical data of 53 children who attended the Department of Neurology, Wuhan Children's Hospital, from November 2020 to April 2023. All children received PER add-on therapy and were diagnosed with epilepsy of genetic etiology based on whole-exome sequencing. The primary outcome measure was the proportion of children with a reduction in seizure frequency of ≥50% at month 12 of PER treatment (i.e., response rate), and the secondary outcome measures were response rates at months 3 and 6 of treatment. The influencing factors for the efficacy of PER add-on therapy in the treatment of epilepsy of genetic etiology were analyzed, and adverse events were recorded.
RESULTS:
The median follow-up duration was 13.10 months. After 12 months of follow-up, 42 children were included in the analysis, comprising 25 boys (60%) and 17 girls (40%). The median initial dose of PER was 1.5 (1.0, 2.0) mg/d, and the median maintenance dose was 4.0 (3.0, 8.0) mg/d. The response rates to PER at months 3, 6, and 12 of treatment were 61% (30/49), 54% (25/46), and 48% (20/42), respectively. No significant difference in the efficacy of PER was observed between children with mutations in genes encoding different protein functions (P>0.05). The most common adverse event reported was fatigue, observed in 3 children (6%).
CONCLUSIONS
PER add-on therapy demonstrates good efficacy and safety in children with epilepsy of genetic etiology. No influencing factors for the efficacy of PER have been identified to date.

OBJECTIVES:
To summarize the clinical and genetic characteristics of epilepsy with intellectual disability caused by SETD1B gene variants in children.
METHODS:
A retrospective analysis was conducted on the clinical data of three children with SETD1B gene variants diagnosed and treated at the Department of Pediatric Neurology of Xiangya Hospital of Central South University. Relevant literature was reviewed to summarize the clinical characteristics of this condition.
RESULTS:
All three children presented with symptoms during infancy or early childhood, including mild intellectual disability and myoclonic seizures, with two cases exhibiting eyelid myoclonia. After treatment with three or more antiepileptic drugs, two cases achieved seizure control or partial control, while one case remained refractory. Each of the three children was found to have a heterozygous variant in the SETD1B gene (one deletion, one frameshift, and one missense variant). To date, 54 cases with SETD1B gene variants have been reported, involving a total of 56 variants, predominantly missense variants (64%, 36/56). The main clinical manifestations included varying degrees of developmental delay (96%, 52/54) and seizures (81%, 44/54). Among the 44 patients with seizures, myoclonic (20%, 9/44) and absence seizures (34%, 15/44) were common, with eyelid myoclonia reported in six cases. Approximately one-fifth of these patients had poorly controlled seizures.
CONCLUSIONS
The primary phenotypes associated with SETD1B gene variants are intellectual disability and seizures, and seizures exhibit distinct characteristics. Eyelid myoclonia is not uncommon.

The patient was a girl, aged 10 years, who was admitted due to fever for 5 days and pancytopenia in peripheral blood for 2 days. Bone marrow examination showed the presence of phagocytic activity, and peripheral blood tests showed pancytopenia, an increase in ferritin, a reduction in fibrinogen, increases in triglyceride and sCD25, and a reduction in natural killer cell activity, which led to the diagnosis of hemophagocytic lymphohistiocytosis (HLH). On the day of admission, the child developed convulsions and rapidly progressed to refractory status epilepticus, which was consistent with the manifestations of febrile infection-related epilepsy syndrome. HLH was controlled after active immunotherapy, with the sequela of refractory epilepsy, and her cognitive function was essentially within normal limits. This article reports the condition of febrile infection-related epilepsy syndrome caused by HLH for the first time in China, in order to improve the awareness of this disease among clinicians.

BACKGROUND AND OBJECTIVES
Epilepsy is a very common pediatric neurologic disorder, and the mainstay of treatment is the use of anti-seizure medication. Several factors may cause inadequate adherence leading to uncontrolled seizures, lower quality of life, and neurodevelopmental consequences. This study aimed to determine medication adherence of adolescents with epilepsy and identify factors that may be associated in medication adherence.
METHODSThis is a prospective cross-sectional study involving adolescents with epilepsy. A self-reported survey was used to measure adherence. Data on demographics and epilepsy were then assessed for presence of association with adherence.
RESULTSFifty-one participants were included. Of these, 19.6% were non-adherent, 35.3% had medium adherence, and 45.1% had high adherence. Simple logistic regression analysis showed that unemployed primary caregiver is associated with 7.0 times higher odds of having moderate-high adherence and consuming at least three drugs is associated with 0.3 lower odds of having moderate-high adherence.
CONCLUSIONAs high as 80.4% of adolescents were adherent to their medications. The presence of a caregiver who can closely monitor the patient is associated with adherence while intake of several drugs is associated with nonadherence. Future studies may need larger sample size and explore knowledge, attitude, and other social factors that may influence medication adherence.

OBJECTIVES: This study aims to describe the clinical characteristics, treatment received and outcome of patients diagnosed with HLH at the Philippine Children’s Medical Center from 2004 to 2017.
MATERIALS AND METHODS: This cross-sectional analytical study was conducted from June 10, 2023 to June 1, 2024 at the Philippine Children's Medical Center. Detailed information was obtained for each case according to protocol. A complete history was taken from the accompanying caretakers. Children aged 0 to 7 years and 11 months, recently diagnosed with focal epilepsy, were evaluated using the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5-TR) criteria. The level of early child development was determined based on the total Battelle Developmental Inventory-2 developmental quotient score.
RESULTS: The study examined 246 children with focal epilepsy. Significant findings included those children with NDD had a higher median age (4.67 years) compared to those without NDD (3.37 years) (p < .001). A higher proportion of non-NDD children were under one year old. Children without NDD had mothers with higher educational attainment (p = .015) and came from families with higher incomes (p = .003). Neonatal complications such as hypoxic-ischemic encephalopathy (HIE) and sepsis were more common in children with NDD (p = .005 and p = .006). Phenobarbital use was more frequent in children with NDD (p = .001), who also had more abnormal EEG and neuroimaging findings (p < .001). Neurodevelopmental evaluations were conducted later for children with NDD (p < .001). A significant number (75.20%) of children exhibited neurodevelopmental problems, with global developmental delay being most prevalent. Crude analysis showed associations between age, number of antiseizure medications, and delays in evaluation with increased odds of NDD.
CONCLUSIONS: The study offers insights into children with focal epilepsy at a tertiary hospital in the Philippines, emphasizing the impact of low socioeconomic status, age, birth complications and multiple anti-seizure medications. These findings are vital for clinicians to modify care plans through a multidisciplinary approach to enhance outcomes and improve quality of life in this high-risk population.
