RESUMEN

Stroke is one of the major causes of morbidity and mortality throughout the world. Research is going on to find out the factors which are associated with the severity of acute ischemic stroke. One of the factors which has gained interest in the field of research in recent time is serum ferritin. Serum ferritin is an acute phase reactant. It is recently under research as a marker of severity and prognosis of acute ischemic stroke. The aim of this study was to assess the relation of serum ferritin level with the severity of acute ischemic stroke. This cross-sectional study was conducted in the Department of Medicine in Mymensingh Medical College Hospital, Bangladesh from June 2020 to March 2023. In this study, 323 patients with acute ischemic stroke were enrolled. The severity of neurological disability was evaluated in all participants using National Institute of Health stroke scale (NIHSS) within 48 hours of onset of stroke. Blood was taken for estimation of serum ferritin levels within 48 hours of admission. In this study, mean serum ferritin level was 208.3±161.1 ng/ml in patients with acute ischemic stroke. The study showed most of the participants with high serum ferritin level had severe stroke (n=57, 77.0%; p<0.001). A statistically significant correlation was found between NIHSS and serum ferritin levels in acute ischemic stroke patients (r=0.71). This study revealed that serum ferritin level is associated with severity of neurological disability among patients with acute ischemic stroke. Further studies are required to establish the role of serum ferritin as a prognostic marker of acute ischemic stroke.

RESUMEN

Background and purpose:

Dysphagia, characterized by difficulty in swallowing due to neurological deficits, stands out as the foremost contributor to stroke asso­ciated pneumonia (SAP) development. Recent investigations have explored the utility of blood tests, including parameters like neutrophil count, leukocyte count, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and the CRP to albumin ratio (CAR), at the time of admission as potential markers for predicting SAP development. This study is set out to assess predictors of SAP in patients with acute ischemic stroke and dysphagia. 

. Methods:

This retrospective cross-sectio­nal study, conducted at the University of Health Sciences, Neurology Department of Erenkoy Mental Health Neurological Disor­ders in Istanbul, Turkey, between January 2021 and January 2023, assessed 65 indivi­duals with acute ischemic stroke and dysphagia. Excluding specific criteria, clinical and laboratory data were collected. Patients were categorized into SAP and non-SAP groups based on diagnostic criteria. Results provide insights into risk factors of SAP.

. Results:

In this study of 65 stroke patients with dysphagia, 27 (41.5%) developed SAP within the first week. No significant differences in age, gender, comorbidities, or infarct size were observed between the pneumonia-positive and pneumonia-negative groups (p > 0.05). HbA1c levels were significantly lower in the pneumonia-positive group (p = 0.02). Logistic regression revealed that NLR, CAR levels, and the presence of atrial fibrillation (AF) were significant predictors of pneumonia development (p < 0.001).

. Conclusion:

Dysphagia is considered one of the most significant risk factors for SAP. However not all ischemic stroke patients with dysphagia develop SAP; that is the reason we think NLR, CAR, and AF might be predictors of SAP in acute ischemic stroke patients with dysphagia.

RESUMEN

BACKGROUND: Hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal dominant inherited vascular disorder that can involve multiple organs, thus can be associated with so many clinical departments that proper screening and diagnosis of HHT are needed for providing better management of both patients and their family members. CASE PRESENTATION: We present a 58-year-old female patient with recurrent paradoxical brain embolism due to HHT. She received aspirin therapy and underwent pulmonary arteriovenous malformation embolization, recovering well and discharged 3 days postoperatively. Though ischemic stroke caused by HHT-induced vascular disorders has been reported, our patient presented with both recurrent paradoxical brain embolisms and radiologic findings of bilateral globus pallidus manganese deposition at the same time, a combination rarely reported. We also review the literature on the clinical features and management of HHT for prompt diagnosis of this genetic disease behind paradoxical embolism. CONCLUSIONS: When patients with ischemic stroke, especially recurrent ischemic stroke, have combined arteriovenous malformations (AVMs) in single or multiple organs, or clues for AVMs like manganese deposition in globus pallidus, genetic diseases such as HHT may be the reason for ischemic stroke and shouldn't be missed in the evaluation of embolic sources.

RESUMEN

Almost half of ischemic stroke (IS) survivors have poststroke fatigue (PSF) during rehabilitation, which can reduce their rehabilitation compliance and quality of life. The primary link of PSF management is early identification, which can guide bundle of care for prevention. This study aimed to explore the predictive value of serological indicators for guiding bundle of care to prevent the occurrence of PSF among IS survivors. This study was a prospective observational study. A total of 350 patients with IS who were hospitalized in 2 tertiary hospitals in Nanning from October 2022 to September 2023 were selected. The general data of patients and serological indicators within 24 hours of admission were collected. Based on the follow-up results, the patients were divided into the PSF group and the NPSF group. Multivariate logistic regression analysis was used to screen the risk factors affecting the occurrence of PSF, and the receiver operating characteristic curve (ROC curve) method was used to analyze the predictive value of this factor. The incidence of acute-phase PSF among elderly patients with IS was 49.26%. The elevated levels of fasting plasma glucose (FPG) (OR = 1.485, 95% CI: 1.145-1.925, P = .003), total cholesterol (TC) (OR = 1.394, 95% CI: 1.013-1.917, P = .041), C-reactive protein (CRP) (OR = 1.394, 95% CI: 1.013-1.917, P = .041), and homocysteine (Hcy) (OR = 1.370, 95% CI: 1.233-1.524, P < .001) were risk factors of PSF in elderly patients with acute IS (P < .05). FPG (area under the curve = 0.632), TC (area under the curve = 0.621), CRP (area under the curve = 0.889), and Hcy (area under the curve = 0.807) had a good predictive value for acute-phase PSF, and the combination of the 4 indicators could further improve the predictive efficacy (area under the curve = 0.938, sensitivity 86.2%, specificity 90.7%, P < .05). The elevated levels of FPG, TC, CRP, and Hcy could predict the risk of PSF, and the combination of the 4 indicators can effectively improve prediction efficiency and provide a reference for guiding the formulation of bundle nursing programs.

RESUMEN

BACKGROUND: The underlying functional alterations of brain structural changes among patients with empathy impairment following stroke remain unclear. We sought to investigate functional connectivity changes informed by brain structural abnormalities in multimodal magnetic resonance imaging (MRI) among patients with empathy impairment following stroke. METHODS: We enrolled people who had experienced their first ischemic stroke, along with healthy controls. We assessed empathy 3 months after stroke using the Chinese version of the Empathy Quotient (EQ). During the acute phase, all patients underwent basic magnetic resonance imaging (MRI), followed by multimodal MRI during follow-up. Our MRI analyses encompassed acute infarction segmentation, volumetric brain measurements, regional quantification of diffusion parameters, and both region-of-interest-based and seed-based functional connectivity assessments. We grouped patients based on the severity of their empathy impairment for comparative analysis. RESULTS: We included 84 patients who had stroke and 22 healthy controls. Patients had lower EQ scores than controls. Patients with low empathy had larger left cortical infarcts (odds ratio [OR] 4.082, 95% confidence interval [CI] 1.183-14.088), more pronounced atrophy in the right cingulate cortex (OR 1.248, 95% CI 1.038-1.502), and lower scores on the Montreal Cognitive Assessment (OR 0.873, 95% CI 0.74-0.947). In addition, the cingulate cortex served as the seed in the seed-based analysis, which showed heightened functional connectivity between the anterior cingulate gyrus and the right superior parietal lobule, specifically in the low-empathy group. LIMITATIONS: We did not evaluate the relationship between specific network involvement and empathy impairment among patients following stroke. CONCLUSION: Among patients with subacute ischemic stroke, reduced empathy was strongly associated with a more severe cognitive profile and atrophy of the right cingulate cortex. Our subsequent structural-informed functional MRI analysis suggests that the enhanced connectivity between the anterior cingulate gyrus and the superior parietal lobule may function as a compensatory mechanism for this atrophy.

RESUMEN

Background and Objectives: The association between neurological disability, prognosis, and telomere length (TL) in patients with stroke has been investigated in various ways. However, analysis of the type of stroke and ischemic stroke subgroups is limited. In this study, we aimed to determine the association between TL and neurological disability according to stroke type. Materials and Methods: This prospective study included patients with stroke who visited a single-center emergency department (ED) between January 2022 and December 2023. The association between TL and neurological disabilities, using the Modified Rankin Scale (mRS) and National Institutes of Health Stroke Scale (NIHSS), was evaluated according to the patient's stroke type and subgroup of ischemic stroke. Multivariate analysis was performed to determine the association between neurological disabilities in patients with ischemic stroke and the subgroups. Results: A total of 271 patients with stroke were enrolled. The NIHSS score was found to be higher at the time of ED visit (adjusted odds ratio [OR], 5.23; 95% confidence interval [CI], 1.59-17.2, p < 0.01) and 1 day later (adjusted OR, 7.78; 95% CI, 1.97-30.70, p < 0.01) in the ischemic stroke group with a short TL. In the other determined etiology (OD) or undetermined etiology (UD) group, the NIHSS was higher in the short TL group at the ED visit (adjusted OR, 7.89; 95% CI, 1.32-47.25, p = 0.02) and 1 day after (adjusted OR, 7.02; 95% CI, 1.14-43.47, p = 0.04). Conclusions: TL is associated with neurological disability in early ischemic stroke and is prominent in the UD and OD subgroups.

RESUMEN

Stroke-heart syndrome (SHS), a critical yet underrecognized condition, encompasses a range of cardiac complications that arise following an ischemic stroke. This narrative review explores the pathophysiology, clinical manifestations, and implications of SHS, focusing on the complex interplay between the brain and the heart. Acute ischemic stroke (AIS) triggers autonomic dysfunction, leading to a surge in catecholamines and subsequent myocardial injury. Our review highlights the five cardinal manifestations of SHS: elevated cardiac troponin (cTn) levels, acute myocardial infarction, left ventricular dysfunction, arrhythmias, and sudden cardiac death. Despite the significant impact of these complications on patient outcomes, there is a notable absence of specific guidelines for their management. Through a comprehensive literature search, we synthesized findings from recent studies to elucidate the mechanisms underlying SHS and identified gaps in the current understanding. Our findings underscore the importance of early detection and multidisciplinary management of cardiac complications post-stroke. Future research should focus on establishing evidence-based protocols to improve clinical outcomes for stroke patients with SHS. Addressing this unmet need will enhance the care of stroke survivors and reduce mortality rates associated with cardiac complications.

RESUMEN

The circadian variation in stroke occurrence is a well-documented phenomenon. However, the circadian effect on stroke outcome, particularly on post-stroke cognition, has not yet been fully elucidated. We aim to evaluate the influence of diurnal variation of stroke onset upon post-stroke cognition and development of post-stroke depression. Based on 4-hourly time period of stroke occurrence, 249 recruited cohorts were categorized into 6 groups. Several clinical and cognitive parameters were compared among the groups. Then, the mRNA expression of core clock genes in Peripheral Blood Mononuclear Cells were quantified and correlated with post-stroke outcomes among 24 acute phase cases with day-time or night-time stroke occurrence. Furthermore, the genetic susceptibility towards a higher number of cases in the morning was examined by genotyping CLOCK (rs1801260T/C, rs4580704G/C) and CRY2 (rs2292912C/G) genes variants in cases and 292 controls. In our study, the peak for highest incidence although observed during the early morning from 4 to 8 am, the nocturnal-onset stroke cases showed more severity (12.2 ± 5.67) at the time of admission irrespective of arterial territory involved. The night onset cases were also found to be more susceptible to develop language impairment and post-stroke depression in due course of time. Upon transcript analysis, circadian genes (BMAL1 and CRY1) were found to be downregulated in night-time cases than day-time ones during the acute phase of onset. In addition, those mRNA levels also showed a correlation with raw scores for language and depression. However, the difference in incidence frequency along a day did not reveal any genetic correlation. Therefore, we suggest night-time stroke to be positively associated with higher immediate severity and poor cognitive outcome than day-time injury and propose downregulation of circadian genes during the acute phase could be the underlying molecular mechanism for this.

RESUMEN

Thrombosed cerebral aneurysms can cause embolism of the distal cerebral arteries and manifest as the development of ischemic stroke or transient ischemic attack. As a rule, thromboembolic complications develop with giant and large aneurysms, but they are also possible with sizes less than 1 cm. In case of such complications, according to the standards of treatment of ischemic stroke, antithrombotic therapy is necessary, which is associated with the risk of rupture of the aneurysm. The article presents our own clinical observation of the development of ischemic stroke against the background of an embolism from the sac of a thrombosed aneurysm of the internal carotid artery in a young patient, which was later complicated by aneurysm rupture and subarachnoid hemorrhage, which required urgent surgical intervention.

RESUMEN

Ischemic stroke (IS) and subsequent neuropsychiatric disorders are among the leading causes of disability worldwide. Several strategies have been previously proposed to utilize exosomes for assessing the risk of IS-related diseases. The aim of this work was to evaluate serum exosomal proteins in IS patients during the chronic post-stroke period and to search for their associations with the development of post-stroke mild cognitive impairment (MCI). Comparative quantitative proteomic analysis of serum exosomes of patients without post-stroke MCI (19 patients mean age 52.0 ± 8.1 years) and patients with post-stroke MCI (11 patients, mean age 64.8 ± 5.6 years) revealed significant differences in the levels of 62 proteins out of 186 identified. Increased levels of the proteins associated with immune system and decreased levels of the proteins involved in lipid metabolism were observed in the patients with MCI compared to the patients without MCI in the chronic post-stroke period. The obtained data suggest that the higher level of immune system activation in the patients during a relatively long period after IS may be one of the risk factors for the development of post-stroke cognitive disorders and suggest participation of exosomal transport in these processes.

RESUMEN

BACKGROUND: Congenital agenesis of internal carotid artery (ICA) is a rare cerebrovascular variation entity. Most cases of congenital ICA agenesis are asymptomatic and discovered incidentally. Congenital ICA agenesis presenting as ischemic stroke is even rare. CASE PRESENTATION: An 80-year-old male patient was admitted to our hospital due to sudden dysarthria and left limb weakness for 3.5 h. Based on emergency physical examination and head computed tomography (CT) scan results, acute ischemic stroke (AIS) of right cerebral hemisphere was suspected. Following intravenous thrombolysis with recombinant tissue plasminogen activator, right congenital agenesis of ICA was confirmed by CT and digital subtraction angiography. Additionally, there was a severe right vertebral artery ostial (VAO) stenosis. After ruling out common causes of AIS such as haematological diseases, arterial dissection, organic heart disease, immunological abnormality and underlying possible malignancies, we hypothesize that the severe stenosis of the right VAO may have contributed to the development of AIS in this case. CONCLUSIONS: We present a case of right congenital ICA agenesis in which severe stenosis of the right VAO may have played a role in the development of AIS. This case underscores a rare scenario where a lesion in the posterior circulation leads to an infarction in the anterior circulation in the setting of congenital ICA agenesis.

RESUMEN

This study investigated the oxygenation in the prefrontal cortex (PFC) during walking in a 75-year-old male patient in the acute phase of a left frontal lobe cerebral infarction complicated by severe left internal carotid artery stenosis. The patient regained independent ambulation on the fifth day after the onset of symptoms, and the study was conducted on the eighth day after the onset of symptoms. The patient rested for 10 s before walking for 70 s. Then he rested for 60 s. The levels of oxyhaemoglobin (O2Hb), deoxyhaemoglobin (HHb), and total haemoglobin (THb) in the PFC were quantified during the rest and walking phases using a wearable near-infrared spectroscopy device. Comparative analysis with baseline values during rest revealed decreases in the O2Hb, HHb, and THb in both hemispheres of the PFC during walking (O2Hb: -19.76/ -14.88 µmol/L, HHb: -1.18/ -2.00 µmol/L, THb: -20.96/ -16.88 µmol/L, right/left, respectively). The recovery of the O2Hb was delayed by 15.8 seconds in the affected hemisphere. These findings support the effectiveness of wearable NIRS for the evaluation of cerebral oxygenation during rehabilitation in patients with acute stroke to facilitate evaluations and individualise patient care.

RESUMEN

BACKGROUND: Excessive daytime sleepiness (EDS) is a common complication of stroke that has a detrimental effect on patients' daily life and functional recovery. The clinical characteristics and risk factors for poststroke EDS may differ between males and females. METHODS: A retrospective study based on hospital medical records was conducted on patients with a diagnosis of stroke who participated in polysomnographic monitoring at the Affiliated Hospital of Yangzhou University from February 2022 to May 2024. Baseline data, laboratory test data, polysomnographic data, and related scale scores were retrospectively collected. The Epworth Sleepiness Scale (ESS) score was used to assess EDS after stroke. Binary logistic regression was used to determine the risk factors for daytime sleepiness. The study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. Statistical analysis was performed via IBM SPSS 26.0. RESULTS: ESS scores were higher in males than in females, whereas females had higher Pittsburgh Sleep Quality Index (PSQI) scores and Hospital Anxiety and Depression Scale (HADS) scores. Male sex and higher depression scores were risk factors for EDS; among male patients, higher anxiety scores were a risk factor for EDS, whereas smoking was a protective factor. Depression, a higher arousal index and a reduced proportion of N3 sleep periods were risk factors for EDS in females. CONCLUSIONS: The characteristics and influencing factors of EDS differ between the sexes in patients with mild and moderate ischaemic stroke. Our study may provide evidence and guidance for clinical diagnosis and treatment. Interventional studies are needed to assess the impact of treating these risk factors in the future.

RESUMEN

BACKGROUND: Pre-existing comorbidities increase the likelihood of post-stroke dysphagia. This study investigates comorbidity prevalence in patients with dysphagia after ischemic stroke. METHODS: The data of patients with acute ischemic stroke from two large representative cohorts (STROKE-CARD trial 2014-2019 and STROKE-CARD registry 2020-2022 - both study center Innsbruck, Austria) were analyzed for the presence of dysphagia at hospital admission (clinical swallowing examination). Comorbidities were assessed using the Charlson Comorbidity Index (CCI). RESULTS: Of 2054 patients with ischemic stroke, 17.2% showed dysphagia at hospital admission. Patients with dysphagia were older (77.8 ± 11.9 vs. 73.6 ± 14.3 years, p < 0.001), had more severe strokes (NIHSS 7(4-12) vs. 2(1-4), p < 0.001) and had higher CCI scores (4.7 ± 2.1 vs. 3.8 ± 2.0, p < 0.001) than those without swallowing impairment. Dysphagia correlated with hypertension (p = 0.034), atrial fibrillation (p < 0.001), diabetes (p = 0.002), non-smoking status (p = 0.014), myocardial infarction (p = 0.002), heart failure (p = 0.002), peripheral arterial disease (p < 0.001), severe chronic liver disease (p = 0.002) and kidney disease (p = 0.010). After adjusting for relevant factors, the associations with dysphagia remained significant for diabetes (p = 0.005), peripheral arterial disease (p = 0.007), kidney disease (p = 0.014), liver disease (p = 0.003) and overall CCI (p < 0.001). CONCLUSIONS: Patients with multiple comorbidities have a higher risk of developing post-stroke dysphagia. Therefore, early and thorough screening for swallowing impairment after acute ischemic stroke is crucial especially in those with multiple concomitant diseases.

RESUMEN

The stress hyperglycemia ratio (SHR) is established as a reliable marker for assessing the severity of stress-induced hyperglycemia. While its effectiveness in managing patients with Acute Ischemic Stroke (AIS) remains to be fully understood. We aim to explore the relationship between SHR and clinical prognosis in AIS patients and to assess how diabetes status influences this relationship. In this study, we analyzed data from the Medical Information Mart for Intensive Care (MIMIC-IV) database, selecting patients with AIS who required ICU admission. These patients were categorized into tertiles based on their SHR levels. We applied Cox hazard regression models and used restricted cubic spline (RCS) curves to investigate relationships between outcomes and SHR. The study enrolled a total of 2029 patients. Cox regression demonstrated that a strong correlation was found between increasing SHR levels and higher all-cause mortality. Patients in the higher two tertiles of SHR experienced significantly elevated 30-day and 90-day mortality rates compared to those in the lowest tertile. This pattern remained consistent regardless of diabetes status. Further, RCS analysis confirmed a progressively increasing risk of all-cause mortality with higher SHR levels. The findings indicate that SHR is association with increased 30-day and 90-day mortality among AIS patients, underscoring its potential value in risk stratification. Although the presence of diabetes may weaken this association, significant correlations persist in diabetic patients.

RESUMEN

Cognitive behavioral stress management (CBSM) relieves physical and psychological burdens in patients with some central nervous system diseases, while its utility in acute ischemic stroke (AIS) patients is unclear. This study aimed to explore the effect of CBSM on neurologic recovery and psychosomatic health in AIS patients. Totally, 176 naive AIS patients were randomized into routine care (RC) group (n=88) and CBSM group (n=88) to receive a 3-month corresponding intervention. Modified Rankin scale (mRS) scores at the first month after discharge (M1) (P=0.008) and the third month after discharge (M3) (P=0.016) were lower in the CBSM group than in the RC group. The proportion of AIS patients with mRS score >2 at M3 was reduced in CBSM group vs RC group (P=0.045). Hospital anxiety depression scale (HADS)-anxiety score at M3 (P=0.016), HADS-depression score at M3 (P=0.005), and depression rate at M3 (P=0.021) were decreased in the CBSM group vs the RC group. EuroQol-5 dimension scores at M1 (P=0.024) and M3 (P=0.012) were decreased, while EuroQol-visual analogue scale score at M3 (P=0.026) was increased in the CBSM group vs the RC group. By subgroup analyses, CBSM had favorable outcomes in AIS patients with age ≤65 years. CBSM was beneficial to neurologic recovery and distress relief in AIS patients with an education level of middle school or above, and to health status in those with an education level of primary school or uneducated. In conclusion, CBSM benefitted neurologic recovery and psychosomatic health in AIS patients with minor neurological deficits, however, further studies should verify these results with a larger sample size and longer follow-up.

RESUMEN

OBJECTIVE: To evaluate the effect of Cortexin treatment on cognitive function and quality of life for young patients after ischemic stroke. MATERIAL AND METHODS: The open prospective observational study included 30 patients from 18 to 45 years old with confirmed ischemic stroke in the carotid blood supply who received a course of treatment with Cortexin. Before and after therapy, all patients in the study group underwent examination to assess their neuropsychological status (MoCA test), The Short Form-36 (SF-36) questionnaire was used to assess quality of life. The study results were processed using statistical analysis. RESULTS: Based on the results of neurocognitive tests, changes in indicators of neurodynamic, visual-spatial and mnestic functions were determined. Thus, in the beginning of the study the MoCA test scores were 25.1±1.4 points. Over time, there was an improvement mainly in the areas of attention, short-term memory, and multiple aspects of executive functions. However, statistical significance for MoCA was achieved by the end of the second course of treatment with Cortexin (visit 4) - 28.4±1.3 points. Delayed neuropsychological testing showed encouraging results - the achieved level of cognitive functioning was maintained (28.0±1.1). According to SF-36 questionnaire at the stage of inclusion in the observation, low results were noted, which indicated the negative impact of the underlying disease on the daily life of the patient who had suffered a stroke. Low quality of life scores persisted until the third visit; a significant improvement in SF-36 results was recorded at visit 4 and persisted with a positive trend at the fifth visit. CONCLUSION: Cortexin therapy has been shown to be effective, safe and well tolerated in young people with cognitive deficits in the poststroke period.

RESUMEN

BACKGROUND: The patent foramen ovale (PFO) and interatrial block (IAB) are associated with cryptogenic stroke (CS). However, the role of the interaction between PFO and IAB in CS remains unclear. METHODS: This case-control study enrolled 256 patients with CS and 156 individuals without a history of stroke or transient ischemic attack. IAB was defined as P wave duration > 120 ms. PFO was evaluated by contrast transesophageal echocardiography, and classified as no-PFO, low-risk PFO and high-risk PFO. Multiplicative and additive interaction analysis were used to assess the interaction between PFO and IAB in CS. RESULTS: Multiplicative interaction analysis unveiled a significant interaction between IAB and low-risk PFO in CS (OR for interaction = 3.653, 95% CI, 1.115-12.506; P = 0.037). Additive interaction analysis indicated that 68.4% (95% CI, 0.333-1.050; P < 0.001) of the increased risk of CS related to low-risk PFO was attributed to the interaction with IAB. The results were robust in multivariate analysis. However, but no significant multiplicative or additive interaction was observed between IAB and high-risk PFO. When stratified by IAB, high-risk PFO was associated with CS in both patients with IAB (OR, 4.186; 95% CI, 1.617-10.839; P = 0.003) and without IAB (OR, 3.476; 95% CI, 1.790-6.750; P < 0.001). However, low-risk PFO was only associated with CS in patients with IAB (OR, 2.684; 95% CI, 1.007-7.149; P = 0.048) but not in those without IAB (OR, 0.753; 95% CI, 0.343-1.651; P = 0.479). CONCLUSION: The interaction between IAB and PFO might play an important role in CS, particularly in cases with low-risk PFO.

RESUMEN

BACKGROUND: Transcranial direct current stimulation (tDCS) is a therapeutic tool for improving post-stroke gait disturbances, with ongoing research focusing on specific protocols for its application. We evaluated the feasibility of a rehabilitation protocol that combines tDCS with conventional gait training. METHODS: This was a randomized, double-blind, single-center pilot clinical trial. Patients with unilateral hemiplegia due to ischemic stroke were randomly assigned to either the tDCS with gait training group or the sham stimulation group. The anodal tDCS electrode was placed on the tibialis anterior area of the precentral gyrus while gait training proceeded. Interventions were administered 3 times weekly for 4 weeks. Outcome assessments, using the 10-meter walk test, Timed Up and Go test, Berg Balance Scale, Functional Ambulatory Scale, Modified Barthel Index, and European Quality of Life 5 Dimensions 3 Level Version, were conducted before and after the intervention and again at the 8-week mark following its completion. Repeated-measures analysis of variance (ANOVA) was used for comparisons between and within groups. RESULTS: Twenty-six patients were assessed for eligibility, and 20 were enrolled and randomized. No significant differences were observed between the tDCS with gait training group and the sham stimulation group in gait speed after the intervention. However, the tDCS with gait training group showed significant improvement in balance performance in both within-group and between-group comparisons. In the subgroup analysis of patients with elicited motor-evoked potentials, comfortable pace gait speed improved in the tDCS with gait training group. No serious adverse events occurred throughout the study. CONCLUSIONS: Simultaneous anodal tDCS during gait training is a feasible rehabilitation protocol for chronic stroke patients with gait disturbances.
