Active clinical trials for "Stroke"

Establish a clinical cohort of acute ischemic stroke patients and find the determinant of the prognosis.

This observational study will address urinary disorders in subacute stroke patients. Patients without and with urinary disorders will be compared, and treatment outcome will be assessed among the latter.

In the past three decades, the burden of stroke has increased in China and has gradually become the leading cause of death. The data acquisition and medical quality management still need to be improved in China. The purpose of this study was to establish online database of acute stroke patients for stroke management quality evaluation in China.

The purpose of DEFENSE-ELDERLY is to identify the prevalence of AF and evaluate the clinical impact of AF in elderly ESUS patients and no other known sources of stroke besides a high-risk patent foramen ovale, and compare it with elderly ESUS patients without high-risk PFO (no PFO or non-high risk PFOs)

To investigate the prognostic value of Functional Near-Infrared Spectroscopy (fNIRS) in stroke rehabilitation with serial measurements.

MOCSS study is a multicenter prospective clinical cohort study. The purpose of the MOCSS study is to investigate whether there is a correlation between the preoperative cerebral small vessel disease and the incidence of covert stroke after non-cardiac surgery. Cerebral small vessel disease (CSVD) and covert stroke will be diagnosed using multimodal MRI. This study will also investigate whether preoperative CSVD and postoperative covert stroke are related to postoperative cognitive dysfunction and delirium.

Stroke patients frequently suffer from stroke associated pneumonia. Pathophysiologically speaking, dysphagia and central nervous system (CNS)-injury induced immunosuppression largely contribute to the risk for pneumonia. In mouse models for stroke, the self-cleaning mechanisms of the lung are also affected by stroke, possibly further contributing to this risk. The investigators designed a pilot-study to examine the structural and functional integrity of the self-cleaning mechanisms of the lung in stroke patients.

Up to know, there is no clear diagnostic and therapeutic pathway for patients with embolic stroke of undetermined source (ESUS). This prospective registry study, which follows up adult ESUS patients for 36 months, is intended to provide important data for the detection of an individual approach in ESUS patients based on a structured diagnostic and therapeutic pathway.

The goal of this study is to develop a large longitudinal cohort of individuals diagnosed with or at high risk for brain diseases (both neurological and psychiatric in nature), in order to identify risk factors that contribute to neurological and psychiatric diseases over time. The investigators seek to capture relevant information from medical records, electronically administered questionnaires and follow up phone-based interviews. The investigators expect to eventually have sufficient power from our dataset to examine risk factors for a variety of brain disorders, both individually and in aggregate. Our ultimate goal is to offer scientifically validated ways to preserve and promote brain health by working with our patients' needs and tracking their progress over time.

Introduction: Carotid Web (CW) is a common cause of stroke in young patients with a high recurrence rate. The factors associated with recurrences and the appropriate treatment to prevent them are currently unknown. Main objective: To compare recurrences of ischemic stroke (cerebral infarction or transient ischemic attack) in patients with CW according to the preventive treatment. Secondary objectives: To describe the frequency of recurrences in patients with stroke and CW. To compare the risk of complications, especially hemorrhagic complications, in patients with stroke and CW according to the type of preventive treatment given. To describe the clinical and radiological characteristics of CW and identify which are associated with recurrences. To detect genetic polymorphisms associated with the presence of CW in stroke patients. Study design: Multicenter, prospective registry of consecutive cases with ischemic stroke in which a Carotid Web is detected between 2022 and 2024. All patients with ischemic stroke or transient ischemic attack and age > or = 18 years, in whom a Carotid Web is diagnosed, will be included. Demographic and clinical variables, genetic study (not mandatory), diagnostic methods of CW, reperfusion treatment and secondary prevention will be collected. During a minimum follow-up of six months, vascular events (stroke, transient ischemic accidents, cerebral hemorrhages) and treatments (antiplatelet therapy, anticoagulation, endarterectomy, endovascular therapy) will be collected. Once the registry has been completed, the frequency of recurrences and the factors associated with them will be analyzed. Study population: Patients with ischemic stroke or transient ischemic attack in whom a Carotid Web is detected. It is estimated to obtain data from approximately 100 patients. Variables: Demographic, clinical (past medical history, stroke characteristics), radiological (diagnostic method of CW, morphological characteristics of CW), therapeutic (preventive treatment initiated) and prognostic variables will be collected. Recurrences in the form of stroke or transient ischemic attack (main variable) will be collected during a minimum follow-up of six months. Cerebral hemorrhages, mortality and therapeutic changes during follow-up will also be collected. Ethical considerations: This is an observational registry, with no changes in the management or treatment of the patients included, and with an anonymized data registry. Written informed consent will be requested from the patient or his/her representative for participation in the registry and for obtaining a blood sample for the genetic study.
