        <description><![CDATA[BackgroundsFutile recanalization (FR) poses a significant challenge in endovascular treatment and there is a lack of reliable predictive models for assessing treatment outcomes in stroke. The aim of this study is to develop a robust CT radiomics-clinical ensemble model that predicts FR in patients with acute ischemic stroke (AIS) following endovascular treatment (EVT) utilizing machine learning techniques.MethodsThis study enrolled 101 patients diagnosed with AIS who underwent successful EVT. A total of 946 radiomics features were, respectively, extracted from non-contrast CT (NCCT), contrast-enhanced CT (CECT), and various CT perfusion maps (CBF, CBV, MTT, and TTP) using PyRadiomics prior to the endovascular intervention. Demographic characteristics, along with baseline clinical, laboratory, and angiographic variables, were incorporated as clinical features in the model analysis. Feature engineering was performed using SelectKBest. Five traditional machine learning algorithms were employed for modeling. The dataset was randomly split into a training cohort (n = 71, 70%) and an internal validation cohort (n = 30, 30%). Receiver operating characteristic (ROC) curves were utilized to evaluate the performance of each model.ResultsAmong the 101 patients, FR occurred in 66 individuals (65%), as determined by the modified Rankin Scale (mRS) at 90 days. The ensemble model integrating clinical data, NCCT, and CBV achieved the highest performance, with an area under the curve (AUC) of 0.918 using the CatBoost algorithm.ConclusionThe multimodal CT radiomics-clinical ensemble machine learning model demonstrated excellent predictive capability for identifying FR in AIS patients with large vessel occlusion prior to EVT.]]></description>

        <description><![CDATA[Background and purposeIncreased cough sensitivity is the key pathophysiological mechanism of chronic cough. Although previous studies have focused on peripheral airway receptor sensitization, the role of the central nervous system—particularly the hypothalamic paraventricular nucleus (PVN)—remains unclear. Whether substance P (SP)–expressing PVN neurons contribute to cough hypersensitivity remains unknown.MethodsThree-week-old Hartley guinea pigs were divided into three groups: citric acid (CA), saline control (SA), and blank control (CON). A cough hypersensitivity model was induced by inhalation of 0.4 mol/L citric acid. Cough sensitivity was assessed using a capsaicin challenge, with the C5 threshold defined as the lowest capsaicin concentration inducing ≥5 coughs. Locomotor activity was evaluated using the open-field test. Airway inflammation and goblet cell hyperplasia were examined by HE and PAS staining. SP and c-Fos expression in the PVN were detected by immunofluorescence and Western blot. HSV retrograde tracing was used to analyze the PVN-airway neural pathway associated with cough hypersensitivity.ResultsCompared with the control groups, guinea pigs in the CA group exhibited a time-dependent increase in cough frequency and enhanced cough sensitivity, as indicated by a reduction in the C5 threshold. Histological analysis revealed increased inflammatory cell infiltration and goblet cell hyperplasia in the airways of the CA group. SP and c-Fos expression, along with the proportion of SP/Fos double-labeled neurons in the PVN, were significantly increased in the CA group (all P < 0.05). Viral tracing confirmed the presence of HSV-positive neurons in the PVN, supporting a neural connection between the PVN and the airways.ConclusionActivation of SP-expressing neurons in the PVN is associated with cough hypersensitivity and suggests the presence of a potential PVN–airway neural pathway. These findings provide a theoretical basis for the development of central-targeted therapies for chronic cough.]]></description>

        <description><![CDATA[ObjectiveThis study aimed to assess the efficacy of ligustrazine in treating cerebral ischemia-reperfusion (I/R) injury and construct a preclinical evidence framework by meta-analysis and machine learning.MethodsA systematic search was conducted for preclinical studies published in PubMed, Embase, Web of Science, and the Cochrane Library up to June 25, 2024. The inclusion criteria encompassed preclinical animal studies pertinent to the topic. Data extraction was performed independently by two individuals, Stata 17.0 software was used for quantitative analysis, R (version 4.3.3) and Python (version 3.11.4) were used for machine learning with neurological function score as the dependent variable.ResultsA total of 23 articles were included, involving 381 animals in the meta-analysis and 321 animals in the machine learning component. Ligustrazine significantly improved neurofunctional scores (NFS) [Longa criteria, SMD = −1.59, 95%CI (−2.16, −1.01), P < 0.001; mNSS criteria, SMD = −1.67, 95%CI (−2.36, −0.97), P < 0.001], cerebral infarct volume (%) [SMD = −2.56, 95%CI (−3.03, −2.09), P < 0.001], and BBB [SMD = −3.06, 95%CI (−4.53, −1.59), P < 0.001]. Furthermore, machine learning analyses, with NFS as the dependent variable, identified the time of first dose, duration, and dose as key determinants of neurofunctional improvement with ligustrazine. Notably, model interpretation suggested that greater improvements were more likely to occur when the initial administration of ligustrazine occurred within 24 h prior to (or 2.21 h post) the ischemic event, at a dosage of 23.53–34.69 mg/kg/day (or 45.71 to 75.65 mg/kg/day), and with an administration duration exceeding 71.43 h.ConclusionThe combination of meta-analysis and machine learning in this study not only confirms that ligustrazine is effective in reducing cerebral I/R injury, but also provides a framework for elucidating the preclinical intervention variables, thus offering novel insights for optimizing preclinical strategies of ligustrazine in cerebral I/R injury.]]></description>

        <description><![CDATA[Chronic stress disrupts homeostasis in the brain and body, leading to anxiety, depression, and cardiovascular and metabolic dysfunction. Although exercise can counter these effects, the mechanisms are scattered across fields and not yet integrated. This review proposes a multi-scale framework. Exercise is not only stress-relieving; it is also a controllable challenge that can recalibrate the system when repeated bouts are matched by sufficient recovery and bioenergetic support. We propose that repeated exercise engages a stress response–adaptation–recovery cycle, in which peripheral signals from skeletal muscles, liver, adipose tissue and gut convey body metabolic state to the brain and are consolidated into durable plasticity only when mitochondrial capacity, substrate availability, and redox balance permit recovery. These signals pass through the blood-brain barrier and engage plasticity switches, including neurotrophic signals, epigenetic modification and metabolic coupling, thus stabilizing the neural circuits of threat appraisal, reward processing and contextual memory. By integrating these dimensions, we clarify how exercise can transform short-term physical stress into lasting resilience and provide direction for future research.]]></description>

        <description><![CDATA[High-density CMOS-based neural probes provide unprecedented spatiotemporal resolution for in-vivo electrophysiology, yet accurate validation of implant position remains challenging. Here we present LFP-LOC, a simple and interpretable method for intraoperative validation and refinement of probe anatomical location based on the spatial distribution of local field potential (LFP) power. Using spontaneous activity recordings performed in rodents, we compute power spectral densities in canonical LFP bands and apply dimensionality reduction and clustering to identify electrodes with shared spectral signatures. Across multiple implant sites, probe technologies, electrode layouts, and experimental conditions, the resulting clusters consistently align with anatomical boundaries. Applied to high-density probes with up to 1,024 electrodes/channels and sub-30 μm pitch, power features converge within approximately 20 s of recordings, allowing online intraoperative assessment. By leveraging the robust relationship between LFP power and brain structure, LFP-LOC enables rapid validation and adjustment of probe placement during surgery, complements histological validation, and may facilitate mesoscale electrophysiological studies.]]></description>

        <description><![CDATA[IntroductionTheta-band transcranial alternating current stimulation (tACS) has been proposed to enhance working memory (WM) by entraining endogenous oscillations, yet the haemodynamic signatures accompanying theta-tACS–related WM gains remain unclear. We investigated whether 6 Hz tACS modulates prefrontal task-evoked haemodynamic responses during WM and whether such changes relate to behavioral improvement.MethodsIn a randomized, single-blind, sham-controlled design, healthy adults (18–30 years) were allocated to 6 Hz tACS or sham (initially n = 25 per group). Stimulation (1mA peak-to-peak, 20min, 30-sramp-up/down) was delivered bilaterally over the dorsolateral prefrontal cortex (DLPFC; F3/F4). Participants completed the Digit Span Test and N-back tasks (1-, 2-, 3-back) before and after stimulation. During N-back performance, fNIRS recorded bilateral DLPFC signals. Task-evoked oxygenated hemoglobin (HbO) β coefficients were estimated using a general linear model. Group differences in pre–post changes were tested using within-/between-group analyses and ANCOVA, with brain–behavior coupling assessed via Spearman correlation.ResultsAfter fNIRS quality control, 44 participants were included in the final analysis; six participants were excluded because more than 30% of channels were identified as low quality. Relative to sham, 6 Hz tACS produced greater improvements in backward Digit Span and total Digit Span. In the N-back task, accuracy improved selectively under the high-load 3-back condition (between-group change: [F(1.40) = 12.29, p_adj = 0.0034, η2p = 0.24)], whereas reaction time showed no significant between-group differences. fNIRS revealed post-stimulation increases in left DLPFC HbO-β during 3-back, with a significant between-group β-change at one channel [(F(1.40) = 10.69, p_adj = 0.035)]. Within the 6 Hz group, 3-back accuracy gains correlated positively with β-change in the left DLPFC (ρ = 0.44, p_adj = 0.039).ConclusionBilateral 6 Hz tACS selectively enhances high-load WM accuracy and is accompanied by increased task-evoked haemodynamic activation in the left DLPFC. The observed brain–behavior coupling suggests that theta-frequency neuromodulation may facilitate executive control under high cognitive demand via strengthened prefrontal neurovascular responses.]]></description>

        <description><![CDATA[Steroid receptor coactivator-1 (SRC-1), also known as nuclear receptor coactivator-1 (NCOA1), represents the first identified member of the p160 nuclear receptor coactivator family and plays a pivotal role in integrating steroid hormone signals, regulating gene transcription, and maintaining neural homeostasis in the central nervous system (CNS). SRC-1 exhibits region-specific, cell-type-specific, and sexually dimorphic expression patterns in the brain, with prominent distribution in key regions including the hippocampus, cerebral cortex, hypothalamus, and amygdala. Functional studies demonstrate that SRC-1 participates in diverse neural functions such as learning and memory, energy metabolism, emotional regulation, and reproductive behavior through modulation of synaptic plasticity-related genes, neurotrophic factors, and metabolic pathways. Aberrant SRC-1 expression is closely associated with neurodegenerative diseases, autism spectrum disorders, and glioblastoma. This review systematically summarizes the molecular structure, expression characteristics, physiological functions of SRC-1, and its roles in neurological disorders, while discussing its potential applications as a diagnostic biomarker and therapeutic target.]]></description>

        <description><![CDATA[BackgroundPerioperative neurocognitive disorders (PNDs) are common and clinically significant complications in older surgical patients. Dexmedetomidine (DEX) has been investigated for neuroprotection; however, reported outcomes across PNDs subtypes remain inconsistent.MethodsFollowing PRISMA-ScR guidelines, we systematically searched PubMed, Embase, and Cochrane Library up to December 9, 2025. Eligible studies included patients aged ≥ 60 years undergoing non-cardiac surgery who received perioperative DEX. Data on study design, intervention characteristics, and cognitive outcomes were extracted and thematically synthesized.ResultsTwenty-seven studies (n = 9,890 patients) were included. DEX effects varied by PNDs subtype and assessment timing. For delayed neurocognitive recovery (dNCR), 13 of 19 studies demonstrated improved cognitive performance or reduced incidence. For postoperative delirium (POD), results were heterogeneous: 6 trials reported significant incidence reduction, whereas 4 found no effect. None of the four studies assessing long-term postoperative neurocognitive disorder (pNCD) showed benefit. Proposed mechanisms include anti-inflammatory, antisympathetic, analgesic, and neuroprotective pathways. Substantial heterogeneity was observed in DEX protocols, cognitive tools, diagnostic criteria, and application of the updated nomenclature.ConclusionDEX most consistently benefits dNCR, supporting its use in acute postoperative recovery. Its effect on POD is context-dependent, and no protective effect against long-term pNCD is evident. Considerable methodological diversity underscores the need for standardized diagnostic approaches and rigorously designed large-scale trials to clarify DEX’s role in perioperative cognitive protection.]]></description>

        <description><![CDATA[IntroductionNecrotizing enterocolitis (NEC) is a common complication in preterm infants and is associated with significant mortality and long-term morbidity, including gastrointestinal sequelae, brain injury, and developmental delays. This systematic review and meta-analysis examines long-term neurodevelopmental outcomes in infants born at less than 34 weeks’ gestation who survive NEC and identifies specific developmental domains most vulnerable to neurodevelopmental impairment.MethodsThe systematic review was performed according to the PRISMA guidelines. We systematically searched Pubmed (including MEDLINE), Embase and Web of Science for relevant articles. Studies were graded for quality using the GRADE system and bias was assessed using the ROBINS-E Risk of Bias tool. We performed gestational-age stratified subgroup analyses (22–28 weeks versus 29–34 weeks) and evaluated the risk of impairment in different neurodevelopmental domains.ResultsSurvivors of NEC are at increased risk of neurodevelopmental impairment (RR 1.42, 95% CI 1.32–1.53). Several neurodevelopmental domains are negatively impacted, such as motor skills (RR 2.08, 95% CI 1.86–2.32), cognition (RR 1.75, 95% CI 1.57–1.96), vision (RR 4.36, 95% CI 2.91–6.55), hearing (RR 4.09, 95% CI 2.91–5.77) and cerebral palsy (RR 2.48, 95% CI 2.15–2.86). The risk of epilepsy and behavioral problems does not differ between NEC survivors and age-matched controls. This increased risk of impairment after NEC persists after stratification for gestational age and extends into school-age.ConclusionNEC Survivors face an elevated risk of neurodevelopmental impairment, irrespective of gestational age, with deficits spanning multiple developmental domains. These findings highlight the need for targeted, long-term follow-up to enable timely detection and individualized interventions for developmental delays throughout childhood.Systematic review registrationhttp://www.crd.york.ac.uk/PROSPERO, identifier CRD42022322564.]]></description>

        <description><![CDATA[Irritable bowel syndrome (IBS) is a gut-brain interaction disorder characterized by abdominal pain/abdominal discomfort accompanied by changes in bowel motility. Its pathogenesis involves the interaction of multiple factors, including abnormalities of the brain-gut axis, intestinal microbiota dysbiosis, and visceral hypersensitivity. Traditional treatment strategies mainly focus on symptomatic relief, which have limitations such as insufficient targeting and significant side effects. Neuromodulation techniques, as an emerging treatment modality, modulate the central or peripheral nervous system through electrical and electromagnetic means, targeting key pathways of the brain-gut axis. These techniques can regulate gut motility and suppress inflammatory responses, thereby alleviating IBS symptoms. Currently, several techniques are widely applied, including electroacupuncture (EA), Sacral Nerve Stimulation (SNS), transcutaneous auricular vagus nerve stimulation (taVNS), and transcutaneous electrical nerve stimulation (TENS). Multiple clinical trials have confirmed their effectiveness in relieving abdominal pain, improving bowel dysfunction, and enhancing quality of life. However, there are still issues such as significant individual differences and insufficient long-term efficacy data. Future research should focus on the development of personalized treatment plans, exploration of combination therapy strategies, and technological innovation to further enhance their clinical value.]]></description>

        <description><![CDATA[Recent studies have demonstrated the close association of mutations in the dehydrodolichyl diphosphate synthase (DHDDS) gene with neurodevelopmental disorders and the onset of epilepsy. This report describes a female patient harboring a de novo heterozygous variant c.110G>A (p.Arg37His) in the DHDDS gene, characterized by childhood-onset myoclonus-like movement disorder (at age 6) and late-onset epilepsy (at age 17). The movement disorder was remarkably improved through the levetiracetam+ clonazepam+ haloperidol triple therapy, and epileptic seizures were also effectively controlled. A retrospective analysis of 59 epilepsy patients with DHDDS gene variants revealed significant clinical heterogeneity in disease phenotypes caused by DHDDS mutations. Epilepsy was identified as the predominant symptom, commonly accompanied by movement disorders and varying degrees of intellectual disability. Furthermore, while pathogenic mutations in DHDDS tend to be relatively clustered, no definitive genotype-phenotype correlation has been established. This study highlights the clinical manifestations, imaging features, treatment experiences, and genetic testing results through case reports and literature review, thereby providing crucial references for the clinical diagnosis, treatment, and further research of such diseases.]]></description>

        <description><![CDATA[IntroductionDeep brain stimulation (DBS) is an increasingly popular therapeutic method for treating motor symptoms in Parkinson’s disease, but its impact on non-motor symptoms in long-term follow-up remains debated.MethodThe primary objective of this study was to monitor the cognitive functioning, mood, and quality of life in 2 years of unilateral and staged bilateral subthalamic nucleus DBS. A cohort of 30 patients was evaluated at three intervals: before DBS surgery, at 6 months, and 24 months post-surgery. The time points of neuropsychological assessments were set to control the impact of unilateral and bilateral DBS throughout the treatment. Two selected groups, unilateral and bilateral DBS, were also analyzed. The study employed a combination of computerized and paper-based tests to assess cognitive functions, alongside questionnaires to gauge emotional state and quality of life. The cognitive evaluation focused on three domains critical for daily activities: attention and processing speed, learning and episodic memory, and executive functions, including working memory and cognitive flexibility.ResultsAnalysis of the entire cohort from baseline through the two follow-up assessments revealed no decline in cognitive function, mood, or quality of life, alongside significant motor improvement. Additional analyses of the two subgroups—unilateral DBS and staged bilateral DBS—also showed no overall decline in any assessed domain over the 2-year follow-up period. However, comparison of cognitive outcomes with normative data indicated a higher proportion of patients meeting criteria for cognitive decline at the 24-month follow-up in the staged bilateral DBS group compared with the unilateral DBS group.ConclusionThe findings support the long-term overall stability of cognitive function, mood, and quality of life following unilateral and staged bilateral subthalamic DBS. Subgroup analyses did not reveal any significant decline in cognitive measures over time. Nevertheless, individual comparisons with normative data showed a higher proportion of patients with memory deficits in the staged bilateral DBS group after the two-year follow-up.]]></description>

        <description><![CDATA[Motion-related artifacts are inevitable in Magnetic Resonance Imaging (MRI) and can bias automated neuroanatomical metrics such as cortical thickness. These biases can interfere with statistical analysis which is a major concern as motion has been shown to be more prominent in certain populations such as children or individuals with ADHD. Manual review cannot objectively quantify motion in anatomical scans, and existing quantitative automated approaches often require specialized hardware or custom acquisition protocols. Here, we train a 3D convolutional neural network to estimate a summary motion metric in retrospective routine research scans by leveraging a large training dataset of synthetically motion-corrupted volumes. We validate our method with one held-out site from our training cohort and with 14 fully independent datasets, including one with manual ratings, achieving a Spearman Rank correlation of 0.71 vs. manual labels. We also tested the correlation of our predicted motion score with morphometric measurements known to be impacted by motion, achieving significant correlation on most datasets. Furthermore, our predicted motion correlates with subject age in line with prior studies. Our approach shows good generalization across scanner brands and protocols, enabling objective, scalable motion assessment in structural MRI studies without prospective motion correction. Finally, we provide empirical evidence that our motion estimator significantly improve model fitness when studying cortical thickness and volume. Our final model is made openly and freely available through “Agitation," a tool usable as a CLI, python package and integrated in Nipoppy and Boutiques. By providing reliable motion estimates, our method offers researchers a tool to assess and account for potential biases in cortical morphometric analyses.]]></description>

        <description><![CDATA[IntroductionAccurate and reliable detection of speech state transitions is a prerequisite for practical speech brain–computer interfaces (BCIs). While cortical language areas have been extensively studied, it remains unclear whether speech onset information is exclusively localized to these regions or distributed across a broader cortico-subcortical network. Here, we investigated the feasibility of decoding speech state transitions using sparse stereo-electroencephalography (SEEG) recordings that sample both cortical and subcortical structures.MethodsFour Mandarin-speaking epilepsy patients undergoing clinical SEEG monitoring performed a sentence-reading task. Neural signals were segmented and labeled as rest or speech based on acoustic onset. A convolutional neural network was trained to classify speech states using broadband or high-gamma features derived from different anatomical channel subsets. We further evaluated continuous decoding performance, model robustness to channel dropout, and the specific contributions of different brain regions.ResultsSpeech state decoding accuracy exceeded chance level (50%) in all participants, with peak single-participant accuracies surpassing 90%. Models integrating both cortical and subcortical signals generally outperformed those restricted to a single anatomical domain. Notably, broadband signals yielded higher classification accuracy than high-gamma features. In continuous decoding simulations, performance remained above chance, although reduced relative to discretized evaluation. Crucially, decoding accuracy was robust to random channel reduction (up to 50%) and remained above 70% even after excluding classical speech-related cortical regions. Contribution analyses indicated participant-specific patterns of model sensitivity, with relatively higher contributions observed in frontal regions and the thalamus in multiple participants.DiscussionThese findings support the hypothesis that speech state information is represented in a distributed cortico-subcortical network rather than being confined to canonical language areas. The robustness of decoding performance despite channel reduction and regional exclusion suggests that sparsely sampled SEEG data can effectively drive speech detection modules. This study demonstrates the feasibility of utilizing deep brain recordings for speech BCIs, offering a pathway toward more stable and generalized implantable systems. Moreover, such autonomous speech state detection may also serve as an ethical safeguard, ensuring that neural language decoding is activated only during intended communicative acts.]]></description>

        <description><![CDATA[A recent hypothesis suggests that glioma cells and neurons engage in a symbiotic relationships, where neurons tend to use lactate, produced in abundance by the cancer cells, instead of glucose. Consequently, the glucose conserved by neurons becomes accessible to glioma cells, which have a high demand for it. The present monograph further develops this hypothesis, weighing specific cellular and molecular processes in both cell types that allow for these symbiotic relationships. The potential roles in the postulated symbiosis of the glycolytic pathway, the mitochondrial tricarboxylic acid cycle, and its coupled oxidative phosphorylation, glucose and lactate transporters, the excitatory neurotransmitter glutamate, lactate signaling via its receptor, and lactylation, are all considered here. The aim is to provide a wider foundation with greater detail for a better understanding of the proposed symbiosis that could offer several possible experimental avenues to verify its validity.]]></description>

        <description><![CDATA[Objectivep53 plays a critical role in Parkinson's disease (PD) pathogenesis. p53 activation induces mitochondrial dysfunction and reactive oxygen species (ROS) production, contributing to progressive dopaminergic neuron degeneration. Although α-lipoic acid (ALA) exhibits neuroprotective effects in neurodegeneration, its underlying mechanisms remain unclear. This study investigated the neuroprotective role and molecular mechanism of ALA in 1-methyl-4-phenylpyridinium (MPP+)- treated PC12 cells, a cellular model of dopaminergic toxicity.MethodsNeuroprotective effects of ALA on dopaminergic neurons were assessed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay for cell viability, Hoechst 33258 staining and flow cytometry to detect cellular apoptosis, and western blot analysis.ResultsALA treatment significantly inhibited p53 expression and attenuated MPP+-induced apoptosis in dopaminergic neurons. ALA also prevented annexin A2 degradation and protected PC12 cells from MPP+-induced toxicity.ConclusionsALA downregulates p53 expression by preventing annexin A2 degradation, thereby reducing p53 protein levels and providing neuroprotection under neurodegenerative conditions. This suggests the potential of ALA in modulating p53 pathways for PD therapy.]]></description>

        <description><![CDATA[This study aims to jointly extract group-shared connectivity patterns and group-specific temporal and frequency information from multi-frequency dynamic functional network connectivity (dFNC) tensors of healthy controls (HCs) and schizophrenia patients (SZs) using a coupled canonical polyadic decomposition (CCPD) approach. Based on 145 subjects (71 SZs and 74 HCs) from the COBRE dataset, multi-frequency dFNC tensors were constructed via group independent component analysis and a filter-banked connectivity framework. A novel sparse and low-rank constrained CCPD (SLRCCPD) model was proposed to decompose the dFNC tensors, incorporating L1-norm regularization to enhance significant connections and nuclear norm-based low-rank approximation to improve clustering quality. The results revealed significant connectivity differences between SZs and HCs within auditory, somatomotor, cognitive control, visual, and cerebellar networks across five shared dynamic modules. Clustering of group-specific time-frequency weights showed that SZs had significantly higher fractional and dwell time in State 3 at both low- and high-frequency bands, along with fewer state transitions across all bands compared to HCs. The proposed SLRCCPD framework effectively captures abnormal multi-band dynamic functional connectivity in schizophrenia, providing a new computational tool and empirical pathway for investigating brain network dynamics and mechanistic studies of the disorder.]]></description>

        <description><![CDATA[IntroductionDisorders of consciousness (DoC) are common disabling conditions following severe brain injury that impose a substantial burden on families and society. Music intervention, as a non-invasive stimulation method, has garnered increasing attention in the field of neurorehabilitation. However, evidence regarding its awakening effects in patients with DoC remains inconsistent. This study systematically reviewed controlled trials investigating the effects of music intervention on the level of consciousness in patients with DoC and performed an exploratory meta-analysis.MethodsWe systematically searched five databases (PubMed, Cochrane Library, Web of Science, Embase, and CNKI) to identify controlled trials comparing the effects of music intervention and control conditions on the level of consciousness in patients with DoC. The Cochrane RoB 2.0 and ROBINS-I tools were used to assess risk of bias. Statistical analysis was performed using RevMan V5.4.1. The primary outcome was the standardized mean difference (SMD) in consciousness levels, calculated as the change in consciousness scores from baseline to endpoint between the music intervention and control groups.ResultsSeven studies (four randomized controlled trials and three non-randomized studies) comprising 296 patients were included. The meta-analysis showed that the music intervention group had significantly greater improvement in consciousness level scores compared with the control group (SMD = 1.51, 95% CI: 0.57–2.44, P < 0.01), with high heterogeneity across studies (I2 = 91%). Sensitivity analysis indicated that heterogeneity decreased to a moderate level (I2 = 72%) after excluding one study involving interactive music therapy and decreased further (I2 = 34%) after excluding studies with short intervention durations. The GRADE certainty of the evidence was rated very low.ConclusionMusic intervention may improve the level of consciousness in patients with DoC. However, the existing evidence is highly heterogeneous. Intervention type (interactive vs. passive) and intervention intensity may represent potential sources of heterogeneity. Further high-quality studies are required to confirm these hypotheses.]]></description>

        <description><![CDATA[ObjectiveThis study investigated whether combining exercise with transcranial direct current stimulation (tDCS) improves overall cognition, memory, and executive function in older adults.MethodsFollowing PRISMA guidelines, we systematically searched databases including PubMed, Web of Science, CNKI, and Wan Fang for randomized controlled trials (RCTs) examining the combined effect of exercise and tDCS on cognitive function in older adults. Used RStudio (version 4.2.0) to merge effect sizes and represent them as SMD with a 95% confidence interval (CI). The main effects are synthesized using a random effects model, and heterogeneity sources are explored through subgroup regression and sensitivity analysis.ResultsThe combined exercise and tDCS intervention significantly improved global cognitive function in older adults (SMD = 0.62, 95% CI: 0.36 to 0.89, p < 0.0001). Significant enhancements were observed in executive function (SMD = 0.54, 95% CI: 0.16 to 0.92, p = 0.005) and general cognitive ability (SMD = 0.75, 95% CI: 0.21 to 1.30, p = 0.006), while memory showed a non-significant improvement (SMD = 0.58, 95% CI: −0.03 to 1.19, p = 0.063). Both interventions lasting less than 6 weeks (SMD = 0.94, 95% CI: 0.60 to 1.27, p < 0.0001) and those lasting 6 weeks or longer (SMD = 0.24, 95% CI: 0.10 to 0.37, p = 0.0006) positively impacted cognitive function. However, the effect size was larger for cognitively healthy older adults (SMD = 0.69, 95% CI: 0.20 to 1.18, p = 0.006) compared to those with cognitive impairment (SMD = 0.60, 95% CI: 0.29 to 0.92, p = 0.0002). The combination of tDCS and integrated exercise produced the largest effect size (SMD = 1.74), despite high heterogeneity, while the combination of tDCS and Tai Chi produced the smallest but most robust effect (SMD = 0.25, I 2 = 0%), indicating that exercise type significantly regulates the intervention effect of tDCS (p = 0.0015). Regression analysis shows that tDCS stimulation time has a significant positive regulatory effect on cognitive function in elderly people (p = 0.0002), while the combined intervention period (p = 0.030) and single exercise time (p = 0.034) both have a significant negative regulatory effect.ConclusionBased on limited evidence, we found that a combined intervention of exercise and tDCS is a potentially effective means of improving cognitive function in older adults. However, the extent of improvement varies with the cognitive domain, baseline performance level, and intervention plan.]]></description>
