The prevalence and the burden of neurodegenerative diseases is projected to increase in the future, but therapeutic options remain limited, relatively invasive, and not readily accessible. In this context, non-invasive brain stimulation (NIBS) techniques, mainly transcranial magnetic stimulation (TMS) and transcranial electrical stimulation (tES), are emerging as safe and reliable instruments to enhance cognitive performance in asymptomatic individuals and patients with cognitive decline. Nevertheless, these techniques face some limitations that delay their deployment in clinical practice. Here, we describe the current status in the development of these technologies for the treatment of neurodegenerative diseases, and we present a novel promising approach for focally and non-invasively target deep brain regions. In light of these technological advances, we then propose a stepwise research roadmap to achieve an effective clinical translation of these techniques. Firstly, the constitution of open-access multimodal databases will allow to inform future interventions and design a new generation of clinical trials. Secondly, research efforts targeting symptomatic patients will need to assess the impact of NIBS techniques in different forms of dementias and probe their efficacy as disease-modifying therapies. In a future step, randomized clinical trials could focus on highly characterized at-risk populations to probe the impact of NIBS in secondary prevention. Once validated on research grounds, these techniques could enter clinical practice, enhancing cognitive performance in asymptomatic individuals and slowing disease progression in symptomatic patients, ultimately lowering the burden of neurodegenerative diseases. Eventually, NIBS techniques could be integrated into clinical practice within the framework of national Brain Health programs to provide early non-invasive interventions against cognitive decline to patients and individuals at risk.

Background: Continuity of care is critical for optimal stroke rehabilitation, yet gaps in post-stroke services in Saudi Arabia may undermine long-term patient outcomes and recovery. The therapists who care for people with stroke should be aware of patients’ needs post discharge and possess skills to address them. This study explored physiotherapists’ perspectives on gaps in care continuity for stroke patients in Saudi Arabia and identified the training needs required to address these gaps. Methods: An exploratory qualitative study situated within critical realism was conducted using nine semi-structured interviews and three focus groups. Twenty-six physiotherapists who were working in outpatient stroke rehabilitation services participated. Data was analysed using reflexive thematic analysis. Results: Three major themes emerged. Significant gaps in post-stroke care were identified, including the lack of specialised stroke rehabilitation centres and clinical practice guidelines. Participants described both facilitators and barriers to implementing continuity of care approaches, such as telerehabilitation, self-management and home care. Further, physiotherapists highlighted the need for comprehensive training in stroke assessment and management, along with the development of standardised patient and caregiver educational protocols to support care continuity. Conclusion: The study highlights the need for targeted training programmes to enhance physiotherapists’ competencies in stroke care. It also calls for systemic collaboration among healthcare organisations and policymakers to develop structured post-stroke services. Full article

The concept of Brain Health is transforming the neuroscientific landscape, promoting an integrative and preventive approach to care under a unifying vision. This position paper, developed by Swiss junior societies in neurology and psychiatry, presents a trainee perspective on how Brain Health should be addressed from the earliest stages of postgraduate training. It explores current gaps in postgraduate training, including the continued separation of neurology, psychiatry and other specialties involved in brain disorder care, limited interdisciplinary and interprofessional exposure, and gaps in leadership, public health, and advocacy skills. We highlight promising models such as Switzerland’s integrated training components and the proposed “brain medicine” framework, inspired by internal medicine. Additionally, we examine innovative initiatives from trainee associations that promote collaborative learning, advocacy, and Brain Health awareness through academic and creative channels. The paper also stresses the importance of equitable global access to training, the integration of research into clinical education, and the urgent need to address burnout and working conditions among early-career professionals. By reframing trainees not as passive learners but as active agents of change, we call for systemic reforms that support their role in advancing Brain Health. Ultimately, we advocate for the development of international core competencies, adaptable curricula, and structured interdisciplinary pathways that embed Brain Health into every level of medical training. Only through this comprehensive approach can we equip the next generation of clinicians to promote lifelong Brain Health across specialties, systems, and populations. Full article

Introduction: Mild traumatic brain injury (mTBI) in older adults (≥65 years) is often underestimated, despite being associated with significant morbidity. Age-related vulnerability, comorbidities, and medication use may exacerbate outcomes. This study aimed to identify predictors of brain health and functional recovery in older adults following mTBI, focusing on acute symptoms, CT imaging findings, and sociodemographic factors. Methods: We analyzed a cohort of 93 older adult patients with mTBI (GCS 13–15) who were prospectively enrolled at a tertiary neurosurgical center. All patients underwent baseline CT, structured clinical assessment, and follow-up at six months with standardized instruments (Glasgow Outcome Scale–Extended-GOSE, 12-Item Short Form Health Survey (quality-of-life measure)-SF-12, Rivermead Post-Concussion Symptoms Questionnaire-RPQ, Patient Health Questionnaire-9 (depression measure)-PHQ-9, PTSD (Post Traumatics Stress Disorder) Checklist for DSM (Diagnostic and Statistical Manual for Mental Disorders)-PCL-5, Timed up and Go Test (mobility measure-TUG test). Multivariate regression was performed to identify independent predictors of recovery. Results: At six months, 94.9% of older adults achieved functional independence (GOSE ≥ 5), though only 43% attained complete recovery (GOSE = 8). Patients with acute intracranial lesions on CT had worse physical outcomes, including slower mobility (mean TUG 17.6 vs. 16.3 s, p = 0.012). Severe acute headache independently predicted poorer recovery (lower GOSE and SF-12 PCS). Lower educational attainment correlated with worse functional and quality-of-life outcomes, consistent with reduced cognitive reserve. Psychological outcomes (PTSD and depression rates) were not associated with CT findings but were influenced by social support and sex. Prompt anticoagulation reversal in patients on anticoagulants markedly reduced hemorrhagic complications. Discussion: Older adults with mTBI generally maintain independence but experience reduced physical health and mobility compared to younger patients. Predictors of poorer outcomes include severe acute symptoms, CT-detected lesions, advanced age, and lower educational levels. Psychosocial support mitigated mental health complications. Conclusions: mTBI in older adults is not benign. Clinical, imaging, and sociodemographic factors collectively shape recovery. Early identification of high-risk patients and targeted interventions are essential to preserve brain health and independence in this growing population. Full article

Introduction: Craniotomy, a common neurosurgical procedure, is frequently associated with substantial perioperative challenges and delayed recovery. While Enhanced Recovery After Surgery (ERAS) protocols have demonstrated clear benefits in multiple surgical fields, their application in neurosurgery, particularly elective craniotomy, remains emerging. Objective: This systematic review and meta-analysis aimed to evaluate the efficacy and safety of ERAS protocols in adult patients undergoing elective craniotomy, focusing on key outcomes such as length of hospital stay (LOS), postoperative pain, complications, and functional recovery. Methods: Following PRISMA guidelines, a comprehensive search was conducted in PubMed, Embase, Scopus, Web of Science, and the Cochrane Library up to June 2025. Eligible studies included adult patients (≥18 years) undergoing elective craniotomy and compared ERAS protocols to conventional perioperative care. Primary outcomes were LOS, postoperative complications, pain, early oral intake, and early mobilization. Data extraction and risk of bias assessment (RoB 2.0) were independently performed by two reviewers. Results: Nine randomized controlled trials (RCTs), totaling 1453 patients, were included. Meta-analysis showed that ERAS protocols significantly reduced length of hospital stay (mean difference: −2.17 days; 95% CI: −2.92 to −1.42; p < 0.00001) and decreased the incidence of postoperative nausea and vomiting (odds ratio [OR]: 0.29; 95% CI: 0.19 to 0.44; I2 = 0%). ERAS protocols were associated with higher odds of early mobilization (OR: 6.88; 95% CI: 3.46 to 13.68) and early oral intake (OR: 14.04; 95% CI: 7.80 to 25.26). Postoperative complications were significantly reduced in the ERAS group (OR: 0.49; 95% CI: 0.24 to 0.99; p = 0.048; I2 = 0%). While early urinary catheter removal showed a favorable trend (OR: 13.48), high heterogeneity (I2 = 95.7%) limits interpretability. Postoperative pain on day 1 did not differ significantly between groups (mean difference: −0.37; 95% CI: −2.38 to 1.63; p = 0.72). The overall risk of bias was rated low to moderate across studies. Conclusions: ERAS protocols in elective craniotomy are associated with shorter hospital stays, lower complication rates, reduced PONV, and earlier return to function, without increasing adverse events. These findings support broader implementation of ERAS in neurosurgical practice. Further multicenter RCTs are warranted to standardize and refine ERAS components for craniotomy. Full article

Chronic subdural hematoma (cSDH) is a common neurosurgical condition in the elderly, often resulting from minor head trauma. Traditional surgical treatments such as burr-hole drainage carry recurrence rates of 10–20% and significant risks in older patients, especially those on anticoagulation therapy. Middle meningeal artery (MMA) embolization has emerged as a minimally invasive alternative, aiming to reduce blood flow to the dura and thereby promote hematoma resolution and lower recurrence. We conducted a bibliometric analysis of publications on MMA embolization for cSDH up to December 2023. The analysis shows a sharp increase in research activity over the past decade. North America, Japan, and Europe are leading contributors, with collaborative networks forming among major institutions. Key journals in neurosurgery and neurointervention have published much of this research, and author collaborations are extensive. Frequently used keywords such as “recurrence” and “treatment outcome” reflect an emphasis on reducing rebleeding and improving patient outcomes. In conclusion, MMA embolization is rapidly gaining attention as a promising treatment for cSDH. While early results are favorable and multi-center efforts are expanding the evidence base, further research is needed to establish long-term efficacy, optimize patient selection, and standardize techniques.

Physical and mental health are intrinsically linked. However, healthcare systems, training programs, and clinical practice often operate in silos, creating structural disincentives that exacerbate morbidity, mortality, and economic burden. Integrated care models have consistently demonstrated improved outcomes, enhanced quality of life, and greater cost-effectiveness across a range of neuropsychiatric and chronic disorders. With the launch of the World Health Organization Brain Health Framework (2022) and the Swiss Brain Health Plan (2023–2033), important progress has been made toward integrating mental and brain health. However, current brain health concepts could be further strengthened by more explicitly incorporating the role of the body and physical health, including psychosomatic and social aspects, particularly in terms of their dynamic, bidirectional interactions with the brain. This article further outlines the health-related and economic benefits of integrated care, key challenges to the systematic implementation of mind–body integration within healthcare systems, and proposes strategic directions for embedding body–brain dynamics into research, education, and policy. This includes interdisciplinary teaching, harmonized conceptual models, composite clinical metrics, transferable interventions, and the removal of systemic barriers to establish integrated care pathways and reduce stigma through patient-centered empowerment. Ultimately, the “no health without brain health” ethos demands the conceptual and practical integration of dynamic, bidirectional body–brain interactions. Full article

Background: Brain health is a growing public health priority due to the high global burden of neurological and mental disorders. Promoting brain health across the lifespan supports individual and societal well-being, creativity, and productivity. Objective: To address the need for specialized education in this field, the University of Bern developed a Certificate of Advanced Studies (CAS) in Brain Health. This article outlines the program’s rationale, structure, and goals. Program Description: The one-year, 15 ECTS-credit program is primarily online and consists of four modules: (1) Introduction to Brain Health, (2) Brain Disorders, (3) Risk Factors, Protective Factors and Interventions, and (4) Brain Health Implementation. It offers a multidisciplinary, interprofessional, life-course approach, integrating theory with practice through case studies and interactive sessions. Designed for healthcare and allied professionals, the CAS equips participants with skills to promote brain health in clinical, research, and public health contexts. Given the shortage of trained professionals in Europe and globally, the program seeks to build a new generation of brain health advocates. It aims to inspire action and initiatives that support the prevention, early detection, and management of brain disorders. Conclusions: The CAS in Brain Health is an innovative educational response to a pressing global need. By fostering interdisciplinary expertise and practical skills, it enhances professional development and supports improved brain health outcomes at individual and population levels. Full article

Dementia prevention is a global public health priority, and lifestyle interventions, including nutrition, have gained interest for their potential to maintain cognitive health. Among nutritional interventions, omega-3 polyunsaturated fatty acids (n-3 FA), particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have been widely studied for their potential to support cognitive health. This systematic review evaluated whether n-3 FA supplementation improves global cognition in cognitively unimpaired older adults. Nineteen randomized controlled trials (RCTs) met inclusion criteria, of which five reported significant improvements in global cognition. A random-effects meta-analysis of 11 placebo-controlled RCTs showed no significant effect (SMD = −0.02, 95% CI: −0.07 to 0.04). Heterogeneity in supplement type, dosage, duration, and outcome measures may have contributed to inconsistent findings and limited comparability. Furthermore, methodological quality of the trials was generally low. While current evidence does not demonstrate a significant effect of n-3 FA supplementation on global cognition, future research should prioritize well-powered, longer-duration RCTs that incorporate biomarker monitoring and more appropriate doses. Clarifying the role of n-3 FA in cognitive aging remains essential for informing nutrition-based dementia prevention strategies. Full article

The quality of life (QoL) perception has been studied in neurological diseases; however, there is limited information linking brain morphological characteristics, QoL, and cognition. Human behavior and perception are associated with specific brain areas that interact through diffuse electrochemical networking. We used magnetic resonance imaging (MRI) to analyze the brain region volume (BRV) correlation with the scores of Rand’s 36-item Short Form Survey (SF-36) and cognitive domains (memory and dementia status). We analyzed data from 420 adult participants in the Maracaibo Aging Study (MAS). Principal component analysis with oblimin axis rotation was used to gather redundant information from brain parcels and SF-36 domains. Canonical correlation was used to analyze the relationships between SF-36 domains and BRV (adjusted for intracranial cavity), as well as sex, age, education, obesity, and hypertension. The average age (±SD) of subjects was 56 ± 11.5 years; 71% were female; 39% were obese; 12% had diabetes, 52% hypertension, and 7% dementia. No sex-related differences were found in memory and orientation scores, but women had lower QoL scores. The 1st and 2nd canonical correlation roots support the association of SF-36 domains (except social functioning and role emotional) and total brain volume, frontal lobe volume, frontal pole, lateral orbital lobe, cerebellar, and entorhinal areas. Other variables, including age, dementia, memory score, and systolic blood pressure, had a significant influence. The results of this study demonstrate significant correlations between BRV and SF-36 components, adjusted for covariates. The frontal lobe and insula were associated with the mental health component; the lateral-orbital frontal lobe and entorhinal area were correlated with the physical component. Full article

Adeno-associated virus (AAV) vectors have emerged as powerful tools for in vivo gene therapy, enabling long-term transgene expression in targeted tissues with minimal pathogenicity. This review examines the AAV serotypes used in clinical gene therapy trials for neurodegenerative (central nervous system, CNS) diseases, highlighting their tropisms, engineering advances, and translational progress. We discuss how capsid modifications, cell-specific promoters, and novel delivery routes are enhancing AAV tropism and reducing immunogenicity to overcome current limitations. Key clinical trials in neurodegenerative disorders (such as Parkinson’s, Alzheimer’s, and Huntington’s disease) are summarized, including delivery methods (intravenous, intracoronary, intrathecal, etc.) and outcomes. We further outline the regulatory landscape with recent approvals of AAV-based therapies and ongoing efforts to address safety challenges like immune responses and vector dose toxicity. A more translational, forward-looking perspective is adopted to consider combination therapies (e.g., AAV with immune modulation or genome editing) and strategic directions to improve the next generation of AAV vectors. Overall, continued innovation in AAV vector design and delivery, alongside careful clinical evaluation, is accelerating the translation of gene therapies for neurodegenerative diseases. Full article

Background: Arteriovenous malformations (AVMs) are rare vascular anomalies that can cause intracerebral hemorrhage, particularly in pediatric patients. Low-flow AVMs may not be visualized on initial non-invasive imaging modalities such as MR angiography. Methods: We report a 6-year-old boy who presented with intracerebral hemorrhage and initially had no detectable vascular anomaly on MR angiography and MR venography. Two years later, he was re-admitted with a recurrent hemorrhage. Repeating MR angiography again failed to reveal any vascular pathology. Results: Digital subtraction angiography (DSA) performed later identified a grade 3 low-flow AVM in the left posterior temporal region. The patient underwent successful endovascular treatment with no subsequent neurological deficits. Conclusions: This case underscores the limitations of MR angiography in detecting low-flow AVMs and highlights the essential role of DSA in the definitive diagnosis and management of unexplained intracerebral hemorrhages in pediatric patients.

This report presents two cases of pregnant women positive for folate receptor alpha (FRα) autoantibodies who received folinic acid supplementation. Both had previously given birth to children diagnosed with autism spectrum disorder (ASD). In subsequent pregnancies, folinic acid was administered preconceptionally and continually throughout gestation. The resulting offspring, monitored up to three years of age, exhibited typical neurodevelopment with no signs of ASD. These cases suggest that folinic acid supplementation during pregnancy may mitigate the risk of ASD in children born to mothers with FRα autoantibodies. Full article

(1) Background: There has been a recent growth in evidence regarding the use, value and impact of photobiomodulation therapy for individuals with fibromyalgia. However, the nature of the evidence has, to the best of the authors’ knowledge, not been presented within a scoping review. The objective of this work is to reveal the nature of the evidence, gaps in the evidence, and a map of the evidence considering photobiomodulation therapy against established policy guidelines; (2) Methods: A scoping review was undertaken considering all academic research that has examined the experiences and impact of photobiomodulation therapy on individuals with fibromyalgia; (3) Results: Our results highlight that, indeed, there is plentiful data available to address a high proportion of the concerns portrayed by the National Institute for Healthcare and Excellence. Outcome measures are wide-ranging, albeit demonstrating heterogeneity, and the results are extremely promising; (4) Conclusion: Based on the current evidence, the United Kingdom’s ‘standard of care’ for fibromyalgia needs to be ascertained, and stringent cost-effectiveness data needs to be collected and presented to governing bodies with the aim of integrating recommendations into future healthcare guidelines.
