Abstract

Introduction: 

Post-stroke cognitive impairment (PSCI) affects 30%–70% of stroke survivors and represents a significant barrier to functional recovery and quality of life. This systematic review synthesizes current evidence on multimodal interventions targeting neuroplastic mechanisms to ameliorate cognitive dysfunction following stroke.

Methods: 

Following PRISMA 2020 guidelines, we systematically searched PubMed, Web of Science, Cochrane Library, and Embase for randomized controlled trials published between January 2020 and October 2025. Forty-seven studies met inclusion criteria, encompassing 3,842 participants across diverse intervention modalities including non-invasive brain stimulation (transcranial direct current stimulation, repetitive transcranial magnetic stimulation), cognitive rehabilitation, virtual reality training, computer-assisted cognitive training, and combined multimodal approaches.

Results: 

Narrative synthesis revealed that transcranial direct current stimulation combined with cognitive training consistently yielded the largest improvements in global cognitive function across included trials, followed by repetitive transcranial magnetic stimulation protocols. Several studies also explored pharmacological agents (e.g., cholinesterase inhibitors) as adjunctive components within multimodal protocols.

Discussion: 

Neuroplasticity mechanisms underlying these improvements include enhanced synaptic plasticity, modulation of long-term potentiation, neurogenesis in perilesional regions, functional reorganization of cortical networks, and restoration of interhemispheric balance. Early intervention initiation (within 3 months post-stroke) was associated with enhanced outcomes across modalities. Virtual reality and computer-assisted training demonstrated moderate efficacy with superior patient engagement and accessibility. Evidence supports multimodal, personalized rehabilitation protocols integrating brain stimulation with behavioral interventions to optimize neuroplastic potential. Future research should evaluate combined rehabilitation approaches at the neural level, assess pharmacological treatment effects on neural plasticity, and investigate long-term maintenance of cognitive gains. This review provides evidence-based guidance for clinicians implementing neuroplasticity-informed rehabilitation strategies for post-stroke cognitive recovery.

Serum multi-trace elements and post-stroke cognitive impairment: a prospective observational cohort study

 Once again, useless predictions of impairment rather than delivering EXACT RECOVERY PROTOCOLS that get survivors recovered! I'd have you all fired for incompetence!

 Let's see how long you've been incompetent in not solving this post stroke cognitive impairment problem! Which also proves the board of directors' incompetence for every hospital that isn't solving this problem!

Abstract

Post-stroke cognitive impairment (PSCI) significantly affects stroke survivors. Identifying modifiable risk factors for PSCI is essential. Serum multi-trace elements are crucial for neurological function but vary in concentration among older adults. It remains unclear whether increasing multi-trace elements can reduce the incidence of PSCI. We investigated the associations between baseline serum multi-trace elements and PSCI. The Montreal Cognitive Assessment defined PSCI. We used logistic regression analyses to evaluate the association between serum multi-trace elements and PSCI. Subsequently, we assessed the associations between serum multi-trace elements and three different cognitive domains using the Kruskal–Wallis test. We further evaluated improvements in the predictive ability of serum multi-trace elements. Finally, 626 patients (mean age: 62.85 ± 7.54 years) were followed up for a median of 1.2 years. Lower concentrations of serum iron (odds ratio [OR] = 2.498, 95% confidence interval [CI]: 1.505–4.145) and zinc (OR = 2.015, 95% CI: 1.233–3.293) were associated with a higher PSCI risk. Higher concentrations of serum iron (OR = 0.368, 95% CI: 0.227–0.595) and magnesium (OR = 0.273, 95% CI: 0.164–0.454), along with lower concentrations of serum copper (OR = 0.544, 95% CI: 0.34–0.872), were significantly correlated with a lower PSCI risk. Cognitive impairments varied across multi-trace elements. Serum iron affected wider cognition, while magnesium and copper levels were strongly associated with language and executive function. Adding serum multi-trace elements to the conventional model improved PSCI risk reclassification (area under curve: 0.676–0.718). Multi-trace elements may influence PSCI progression.

Abstract

Background

The impact of noninvasive brain stimulation (NIBS) on cognitive and mental outcomes in Alzheimer’s disease (AD) and mild cognitive impairment (MCI) remains under debate due to contradictory findings from systematic reviews and meta-analyses (SRMAs). To synthesize evidence from SRMAs assessing the effectiveness of NIBS techniques on cognitive and mental outcomes in AD and MCI populations. By comparing our findings to recent reviews and clinical guidelines, we highlight how this study addresses current limitations in the literature, provides a more holistic perspective on NIBS interventions, and guides future research and clinical practice.

Methods

We searched four databases from inception to May 15, 2024, reviewing SRMAs that analyzed the effects of NIBS. Effect sizes, 95% confidence intervals (CIs), and prediction intervals were computed for each meta-analysis. The methodological quality of the SRMAs was evaluated using the Measurement Tool to Assess Systematic Reviews 2, and the quality of evidence was assessed through the Grading of Recommendations, Assessment, Development, and Evaluation criteria.

Findings

Ten SRMAs detailing 22 associations were analyzed, focusing on two NIBS techniques across 12 unique outcomes. Significant improvements were observed in global cognition, language, executive function, and memory. Repetitive transcranial magnetic stimulation (rTMS) significantly enhanced short-term global cognition (standardized mean difference [SMD], 0.44; 95% CI 0.02–0.86), language (SMD, 1.64; 95% CI 1.22–2.06), executive function (SMD, 1.64; 95% CI 0.18–0.83), and long-term global cognition (SMD, 0.29; 95% CI 0.07–0.50). Transcranial direct current stimulation (tDCS) was effective in improving memory (SMD, 0.60; 95% CI 0.32–0.89) and executive function (SMD, 0.39; 95% CI 0.08–0.71). NIBS interventions showed no significant correlation with neuropsychiatric symptoms but demonstrated good tolerability in terms of safety and acceptability.

Interpretation

This umbrella review indicates that NIBS techniques, particularly rTMS and tDCS, can significantly improve cognitive functions such as global cognition, language, executive functions, and memory in patients with AD and MCI. Despite potential benefits, results should be interpreted cautiously due to study heterogeneity and methodological limitations. Future studies should investigate their long-term effects and applicability across dementia types.

Graphical Abstract

Introduction

With an increasing aging population, dementia has become an urgent global public health challenge. According to the World Health Organization, approximately 55 million people worldwide are diagnosed with dementia annually, and this number is expected to rise to 82 million by 2030, with 60–70% of cases attributed to Alzheimer's disease (AD) [1]. AD is a chronic progressive neurodegenerative disease characterized by persistent cognitive decline [2] and neuropsychiatric symptoms (NPS) [3] that severely affect quality of life. Mild cognitive impairment (MCI) represents the transitional state from normal aging to AD, affecting 10–15% of the population aged > 65 years [4]. Approximately 30–40% of people with MCI, especially with memory difficulties, progress to AD and other forms of dementia within five years of diagnosis [5]. The Alzheimer's Association estimates that by 2023, the total expenditure for treating AD and other types of dementia will reach $345 billion [6]. The gradual functional impairment of patients with AD imposes significant costs on society and healthcare systems. Therefore, managing, preventing, and treating MCI and AD to reduce their incidence and healthcare costs represent current challenges.

Standard interventions for AD currently involve pharmacological treatments, specifically acetylcholinesterase inhibitors and N-methyl-D-aspartate antagonists [7]. However, these medications are associated with strong side effects and poor compliance, and therapeutic outcomes often fail to deliver satisfactory results. Non-invasive brain stimulation (NIBS) is a cost-effective supplementary and alternative therapeutic approach frequently used to treat MCI and age-related neurodegenerative diseases [8, 9]. The most widely used NIBS techniques for AD and MCI treatment include repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS). Mechanistically, rTMS uses strong magnetic fields to generate focal currents through a coil to stimulate the brain, which can activate or inhibit neural activity in specific brain areas through high- or low-frequency stimulation, respectively [10, 11]. Conversely, tDCS delivers low-intensity electrical currents via electrodes on the scalp, modulating synaptic transmission by altering the polarization of the neuronal membrane, thereby promoting or inhibiting the generation of neural signals. It is worth noting that other TMS protocols (e.g., theta-burst stimulation) and transcranial electrical stimulation modalities (e.g., transcranial alternating current stimulation and transcranial random noise stimulation) are less frequently employed in clinical trials or routine care, possibly due to their less well-defined mechanisms and the absence of standardized treatment guidelines.

However, systematic reviews and meta-analyses (SRMAs) on the effect of NIBS interventions on cognitive function and neuropsychiatric symptoms in patients with MCI or AD have yielded varying results [12]. The reliability of study outcomes, which may be affected by reporting biases and inadequate statistical power due to small sample sizes, remains a key issue in NIBS research. Additionally, variations in inclusion and exclusion criteria, analytical methods, and risk of bias in SRMAs can lead to inconsistent results and conclusions. These factors may have contributed to the over-representation of significant findings in SRMAs. Furthermore, most SRMAs focus solely on one type of intervention (either rTMS or tDCS) and on specific domains (cognitive function or apathy) [2], which hampers a comprehensive understanding of the subject. Moreover, recent guidelines and reviews often do not integrate findings across different NIBS modalities and a range of cognitive and mental health outcomes, leaving gaps in the literature and unanswered questions regarding the comparative and collective value of these interventions.

Umbrella reviews are valuable tools for synthesizing evidence; identifying, integrating, and evaluating evidence from published SRMAs; and assessing the strength and validity of the evidence based on sample size, effect size, and biases [13, 14]. In this umbrella review, we systematically and comprehensively assessed the relationship between NIBS and cognitive and mental outcomes to provide evidence-based decision-making support to clinicians and rehabilitation specialists.

Abstract: This paper provides an overview of post-stroke cognitive impairment (PCI), the prevalence of which is high (from 24 to 70) and presents social significant problems in patients with prior stroke. Contributing to the disability in these patients is the fact that the role of cognitive impairment is often underestimated and attention is paid only to motor defects. The pathogenesis of PCI may include not only vascular, but also neurodegenerative (due to Alzheimer's disease) mechanisms of brain damage. The diagnosis of early PCI is of great practical importance, as it is most effective to treat mild PCI. The paper considers current approaches to preventing and treating PCI. The authors relate their own experience in treating a patient with moderate PCI.
