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
Spinocerebellar Ataxia (SCA) represents a rare and heterogeneous group of neurodegenerative disorders, typically characterized by the progressive loss of coordination of movement, resulting primarily from cerebellar dysfunction. This case report discusses the history, clinical presentation, and diagnostic findings of a patient who exhibited symptoms suggestive of SCA. Given the notable familial pattern, further evaluation was undertaken using genetic testing. The objective of this paper is to present the clinical, genetic findings, and inheritance pattern of a patient and her family with SCA.
CASE PRESENTATIONOur case is a 36-year-old Filipino female with progressive cerebellar dysfunction for over a decade. Cranial Magnetic Resonance Imaging (MRI) revealed bilateral cerebellar atrophy. Genetic testing identified a Variant of Uncertain Significance (VUS) in the inositol 1,4,5- triphosphate receptor type 1 (ITPR1) gene, a finding consistent with Spinocerebellar Ataxia type 15 (SCA 15). This represents the first reported case of SCA 15 in the Philippines and in Asia.
A detailed pedigree assessment revealed that 18 immediate and extended family members had similar symptoms suggestive of hereditary ataxia. Ten relatives had already passed away, and four could not be contacted for further evaluation. Three available family members were examined and likewise demonstrated comparable cerebellar findings, supporting a familial pattern of the disease.
CONCLUSIONThe findings from this case series suggest that SCA 15 may be present in Filipino families, with an autosomal dominant (AD) inheritance pattern. While no data on the prevalence or incidence of SCA15 in the Philippines currently exists, this report calls attention to the need for further research and genetic studies within the Filipino population.

Introduction:
Electrolyte imbalance is common in central nervous system
infections. Arginine vasopressin deficiency (AVP-D),
Cerebral Salt Wasting (CSW), and Syndrome of Inappropriate Antidiuretic Hormone secretion (SIADH) are important etiologies that can cause opposing extremes of serum
sodium, posing diagnostic and therapeutic challenges.
We report a rare case of transient central AVP-D followed
by CSW secondary to tuberculous meningitis (TBM).
Case:
An 18-year-old female presented with a 1-month history of
fever, reduced responsiveness, and visual hallucinations.
Her Glasgow Coma Scale was E4V1M4 with neck stiffness
and upper motor neuron signs. Initial investigations revealed
severe hyponatremia (119 mmol/L) and communicating
hydrocephalus with third ventricle ballooning on brain
imaging. Coupled with a positive tuberculosis contact,
anti-tuberculous therapy was initiated for probable TBM
alongside 3% saline correction prior to insertion of external
ventricular drain (EVD). Her condition deteriorated on day
5, requiring intubation for aspiration pneumonia. Repeated
imaging showed worsening hydrocephalus, necessitating
EVD revision. She subsequently developed polyuria (urine
output [UO] 150–300 mLs/hour), with biochemical findings
consistent with AVP-D (serum sodium 154 mmol/L; urine osmolality 96 mOsm/kg; urine sodium <20 mmol/L).
Intravenous desmopressin 1 mcg was administered, and
UO reduced to 30 mLs/hour. However, polyuria recurred
on Day 9, accompanied by tachycardia, hypotension, and
a rapid decline in serum sodium to 120 mmol/L. Diagnosis
of CSW was established (urine sodium 204 mmol/L; urine
osmolality 470 mOsm/kg). Oral fludrocortisone was
initiated and titrated to 0.4 mg daily to maintain serum
sodium >130 mmol/L. Due to persistent hydrocephalus,
right ventriculoperitoneal shunt was inserted on Day 22,
after which her UO gradually decreased, allowing tapering
of fludrocortisone. She remains on fludrocortisone 0.1 mg
daily with ongoing rehabilitation.
Conclusion
TBM can be complicated by SIADH, AVP-D, or CSW.
Concurrent AVP-D and CSW have not been reported.
This case highlights the dynamic electrolyte disturbances
in TBM which may lead to diagnostic confusion and
therapeutic error. Early recognition and tailored therapy,
alongside definitive management to reduce intracranial
pressure, are essential for optimal outcomes.

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.

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.

8.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 (<i>Pi>>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.

9.Research progress on phenotypic modifier genes in spinal muscular atrophy.
Chinese Journal of Contemporary Pediatrics 2025;27(2):229-235
Spinal muscular atrophy (SMA) is a common fatal autosomal recessive genetic disorder in childhood, primarily caused by homozygous deletion of the <i>SMN1i> gene. Its main characteristics include the degenerative changes in the anterior horn motor neurons of the spinal cord, leading to symmetrical progressive muscle weakness and atrophy of the proximal limbs. However, SMA patients with the same genetic background often exhibit different degrees of disease severity. In addition to the well-established modifier gene <i>SMN2i>, the effect of other modifier genes on clinical phenotypes should not be overlooked. This paper reviews the latest advancements in the pathogenic and modifier genes of SMA, aiming to provide a deeper understanding of the pathogenic mechanisms and phenotypic differences in SMA, as well as to offer new strategies and targets for treating this condition.

OBJECTIVES:
To explore the efficacy and adverse reactions of nusinersen combined with risdiplam in the treatment of spinal muscular atrophy (SMA).
METHODS:
A retrospective analysis was conducted on the clinical data of 10 pediatric SMA patients treated with nusinersen combined with risdiplam at the Children's Medical Center of Xiangya Hospital, Central South University.
RESULTS:
Among the 10 SMA patients, there were 4 with type I, 4 with type II, and 2 with type III. Nine patients initially received nusinersen monotherapy, while 1 patient received nusinersen combined with risdiplam. The median duration of combination therapy with nusinersen and risdiplam for the 10 patients was 10.5 months (range: 0.5-20.0 months), with 6 patients undergoing combination therapy for more than 6 months, showing improvements in motor and/or respiratory function. The remaining 4 patients had combination treatment durations of 0.5, 1.0, 1.3, and 4.0 months, respectively, with no significant overall improvement. After combined treatment, 5 patients experienced skin hyperpigmentation, 2 had lumbar puncture site pain, 1 experienced vomiting, 1 had increased sputum production, and 1 had reduced total sleep time. All adverse reactions were mild and did not require medical intervention.
CONCLUSIONS
Nusinersen combined with risdiplam demonstrates efficacy in the treatment of SMA, and no significant adverse reactions have been observed.
