Filter by:Acute ischemic stroke has a high incidence, ischemic stroke caused by large vessel occlusion is serious and has a poor prognosis, and its triggers in the short term before onset are not clear. The aim of this study was to evaluate the short-term risk of acute ischemic stroke caused by multiple triggers. In this trial, through a case-crossover study design, patients were asked about the exposure to each trigger in the previous year and the exposure during the preictal risk period (the exposure observed during the risk period) for each potential trigger of acute ischemic stroke caused by large vessel occlusion. To evaluate the relative risk of ischemic stroke resulting from exposure to triggers, comparing exposure during the dangerous period with the usual frequency of exposure. Relative risks and corresponding 95% CIs were estimated for past-year exposure and past-year mean exposure (assessed as chronic risk factors) and time to last exposure (assessed as triggers). Scientifically evaluate exposure to a range of potential triggers, including infection, mood, smoking, alcohol consumption, diarrhea and vomiting, extreme temperature changes, and several factors that increase blood pressure and their risk of developing acute ischemic stroke.
Acute ischemic stroke with large vessel occlusion is a frequently occurring life-threatening condition. Although endovascular treatment can effectively open occluded vessels, the successful reperfusion rate exceeds 80%, but the rate of good prognosis is less than 50%. The current clinical focus is on how to improve futile recanalization. Tirofiban is widely used in the treatment of stroke, as it can effectively prevent vascular reocclusion and improve microcirculation perfusion. It has the potential to improve futile recanalization, but there is a lack of high-level evidence-based medical support. This multicenter, prospective, double-blind, randomized controlled trial was conducted to assess the effectiveness and safety of sequential tirofiban therapy following successful mechanical thrombectomy within 24 hours of onset.
The purpose of this study is to evaluate the effects of a treatment using virtual reality on the recovery of unilateral spatial neglect. The investigators hypothesize that the experimental group underwent to a protocol of active exercises within the virtual environment will show an improvement in the exploratory functions of the left hemispace, investigated with specific scales and clinical tests.
In this exploratory qualitative study with a hermeneutic phenomenological approach, we will describe and understand the experience of treatment and hospitalization in hospitalized people suffering from stroke, multiple sclerosis, Parkinson's disease and patients post-neurosurgery for oncological causes. Patients will be interviewed in a semi-structured manner and sampling will take place for each of the pathology groups according to the saturation method.
We don't know a great deal about why some people develop seizures in adulthood, but some researchers think that it might tell us something about the brain. A small number of people with first seizure in adulthood go on to experience problems like stroke or dementia later in life. However, stroke and dementia are common diseases, so we don't know whether there is a real association between these conditions. When people develop their first seizure in adult life, this is sometimes called Late-Onset Epilepsy. Through the NeuroFrailty study, we will observe 'brain health' over the years following the onset of a seizure, and I hope that it might give us more information about people with these kinds of seizures. The NeuroFrailty study involves observing people from the time of diagnosis of first seizure. At this time, we will look at investigations such as blood tests, blood pressure, brain scans, alongside other diagnoses which might tell us whether there are differences compared to people without seizures. For some people, we will also look in greater depth at lifestyle including exercise, driving, family planning, and memory assessments. Over the following years, we will look at how things change: for example whether there are changes in memory, new diagnoses, medication changes and how lifestyle has changed. Because there is so little research in this area, it is very difficult to predict what might happen. For example, some people can experience worse memory because of medication side effects; on the other hand, good seizure control following a diagnosis can sometimes lead to improved memory. Over years, it may become clear that some diseases are more likely in people with late-onset epilepsy than in people without such a diagnosis. You will receive a yearly newsletter to keep you updated on everything we learn about late-onset epilepsy. Purpose and Background Most of the time, we do not know why an adult develops epilepsy. Some researchers think there may be a connection between epilepsy which starts in adulthood, and increased risk of stroke or dementia in the future. However, there is very little research or evidence in this area, so we cannot say whether this is true. What does taking part involve? This study is an observational study, which means that the management of participants' seizure disorder will not be affected if they choose to take part in this study. The purpose of this study is to watch participants over the course of several years, to find out more about seizures which start in adulthood. Participants can choose the level of involvement that is right for them. 1. LOW involvement. A researcher will check hospital and General Practice (GP records) once or twice per year, for the LIMITED AND SPECIFIC purpose of checking: medications, any new diagnoses, investigations associated with stroke risk (such as cholesterol, blood pressure, heart trace) and any brain scans that have been performed. I will not have access to more detailed information, such as conversations between a participant and their GP. 2. HIGH involvement. This involves being contacted by telephone once per year for 15-30 minutes to ask questions assessing memory and enquiring about lifestyle, such as exercise, smoking and alcohol use. 3. VERY HIGH involvement. These participants will be contacted for a longer telephone conversation 30-45 minutes once per year about their experience of how epilepsy has affected home life, work and medications. If someone decides in the future that they don't want to be involved, they can withdraw from the study. However, once the study is completely finished, the information will be completely anonymous, which means that I won't be able to find individual's information in order to delete it. Glossary Seizure disorder = any disorder which involved having experienced at least one seizure. First seizure and epilepsy both can be classed as a form of seizure disorder. Neurofrailty = A condition whereby a person is at risk of stroke or dementia.
Affecting more than 150,000 patients in France, stroke is a major public health issue and a leading cause of disability worldwide. In western countries, 80-85% of strokes are of ischemic subtype. This study will focus on young adults, aged 18-45, with a diagnosis of ischemic stroke. Studies assessing post-stroke cognition in young patients reported an alarming prevalence of cognitive impairment, affecting about 60% of stroke survivors between 4 and 12 months after the acute event. However, longitudinal data on neurocognitive trajectories (i.e., the evolution of cognitive impairment over time) in young patients with ischemic stroke are lacking. Collecting such data requires an exhaustive neuropsychological assessment and several functional evaluations, at different times, for the same patient. Repeated neurocognitive study of young patients with ischemic stroke will enable: a description of the prevalence of impaired global cognitive efficiency, an analysis of the specific neurocognitive domains affected, and the tracing of trajectories of recovery from cognitive impairment over time, in terms of global cognitive efficiency and as a function of specific neurocognitive domains (memory, executive, attentional, social cognition, instrumental functions, fatigability, etc.). Up to date, the clinic-radiological predictors and associated factors of neurocognitive impairment after ischemic stroke in young patients have not been studied. Ischemic stroke causes acute brain lesions of the gray matter (GM) and white matter (WM). Numerous studies suggest that cognitive health may be more closely linked to the integrity of WM than to GM. Magnetic resonance imaging (MRI), and in particular diffusion tensor imaging (DTI) sequences, analyze WM bundles. By using fiber tracking algorithms image analysis enable the WM fiber bundle reconstruction and allow quantifying the volume of lesions (pre-existing and ischemic stroke-induced) in the WM tract. The aim of this study is to study whether the extension of pre-existing and acute white matter lesions is associated with poorer cognitive recovery after ischemic stroke, both in terms of global cognitive performance and impairment in specific neurocognitive domains.
This prospective observational study will evaluate the potential value of mobile MRI in patients with suspected or proven acute stroke and Transient Ischemic Attack (TIA), undertaking additional imaging in the emergency department, acute stroke unit, or outpatient settings, and comparing diagnostic accuracy, Diffusion-weighted imaging (DWI) lesion volume and detection of complications (brain swelling or haemorrhagic transformation). Information on ease of use, tolerability and image quality will also be gathered.
Telerehabilitation method, which is an alternative to face-to-face rehabilitation practices for stroke patients who need intensive, regular and long-term rehabilitation in the early period, has been popularly used in recent years. Telerehabilitation is a practice in which the patient participates in the treatment via digital media without the need for the patient to come to the clinic.
The study is a prospective multicentre registry study. Patients admitted to 10 stroke centres nationwide from September 2022 to September 2025 with acute ischaemic stroke due to large vessel occlusion considering underlying ICAS and treated with emergency endovascular thrombolysis were included for analysis. Patients who met the general inclusion criteria underwent thrombectomy and the necessary remedial treatment.
The purpose of this study; To determine the relationship between respiratory muscle strength, balance, trunk control, functional capacity and motor functions in stroke patients and compare them with healthy individuals.
