Active clinical trials for "Stroke"

The purpose of this study is to extend the recent Food and Drug Administration (FDA) Sentinel tabulations regarding stroke risk among new users of typical and atypical antipsychotics to participants who were aged 18-64 years and did not have dementia to participants aged 65 years and older regardless of dementia status.

The relation between obesity and stroke recurrence is still under debate. In this study it has been sought whether baseline obesity is associated with recurrent stroke and major cardiovascular events in a long-time period.

This is a comparison of clinical outcomes between a pre-hospital and an in-hospital thrombolysis patient registry.

The purpose of this study is to investigate sleep disordered breathing, autonomic dysfunction, and post stroke depression in acute and chronic stroke patients. Furthermore, to explore the interaction between these comorbidities, and their relation to stroke aetiology.

The overall goal of the CTP to predict Response to recanalization in Ischemic Stroke Project (CRISP) is to develop a practical tool to identify acute stroke patients who are likely to benefit from endovascular therapy. The project has two main parts. During the first part, the investigators propose to develop a fully automated system (RAPID) for processing of CT Perfusion (CTP) images that will generate brain maps of the ischemic core and penumbra. There will be no patient enrollment in part one of this project. During the second part, the investigators aim to demonstrate that physicians in the emergency setting, with the aid of a fully automated CTP analysis program (RAPID), can accurately predict response to recanalization in stroke patients undergoing revascularization. To achieve this aim the investigators will conduct a prospective cohort study of 240 consecutive stroke patients who will undergo a CTP scan prior to endovascular therapy. The study will be conducted at four sites (Stanford University, St Luke's Hospital, University of Pittsburgh Medical Center, and Emory University/Grady Hospital). Patients will have an early follow-up MRI scan within 12+/-6 hours to assess reperfusion and a late follow-up MRI scan at day 5 to determine the final infarct.

This study attempts to elucidate whether stroke patients with dysphagia have reduced diaphragm movement during voluntary coughing, and also during deep inspiration and expiration than stroke patients without dysphagia. This study will also compare various spirometric measurements with the diaphragmatic motions.

In collaboration with the Neurointerventional programs at state university of new york Buffalo, state university of new york Stonybrook, Swedish Medical Center, Erlanger Health System, Vanderbilt University, and West Virginia University School of Medicine, the investigators aim to prospectively collect experiences where direct aspiration as a first pass technique is used for thrombectomy procedures. The investigators also want to compare specific characteristics from these cases to other stroke cases where traditional thrombectomy devices were used.

The purpose of this study is the evaluation and comparison of blood pressure variability indices and ambulatory arterial stiffness index obtained by ambulatory blood pressure monitoring as prognostic indicators in the functional outcome of acute ischemic stroke.

The main objective of this study is to evaluate the metrological characteristics of the data processing algorithms from inertial sensors (FOX © HiKoB) for the reconstruction of movement relative to the reference system (VICON) for measurement of dorsiflexion at the beginning of a step and in the middle of the oscillating phase.

Previous studies on the association between blood pressure variation (BPV) in acute ischemic stroke and functional outcomes yield conflicting result. The obscured definition and measurement of BPV engenders considerable confounding factors, making it difficult to interpret. We aim to investigate the predictive role of 24-hour BPV on early outcomes in acute non-cardiogenic ischemic stroke.
