Active clinical trials for "Cerebral Infarction"

Assess the safety and efficacy of the Q Revascularization System to remove thrombi and emboli from the neurovasculature in patients experiencing an acute ischemic stroke

The purpose of this study is to determine the efficacy and safety of remote ischemic conditioning combined with intravenous thrombolysis in treating acute ischemic stroke.

Background: intravenous alteplase appears to be much less effective at opening proximal occlusions of the major intracranial arteries, which account for more than one third of cases of acute anterior-circulation stroke and expanding time window using mechanical thrombectomy can improve clinical outcome in patients that would have only received conservative treatment. The aim of this work is to evaluate the effectiveness of endovascular therapy within 24 hours of symptom onset and to compare clinical outcome of endovascular therapy with the standard medical therapy at the end of 3rd month follow up. Material and Methods 57 subjects presenting with an acute ischemic stroke caused by occlusion of the proximal middle cerebral artery (M1 segment) or Internal carotid artery ( ICA segment) within 24 hours from symptom onset as documented by Ct, and or MRI perfusion were recruited consecutively from 2 University hospitals Ain shams University Hospital (32 Patients) and Aswan University (25 patients). Assessment of each subject was performed using NIHSS, and MRS, Aspect score, before intervention. Follow up was done using the same clinical scale one week and the 3 month after the onset. Primary outcome NIHSS and MRS at the end of 3 month after the onset. secondary outcome complications (cerebral Hge) and death at 3 months.

Development of stroke associated pneumonia (SAP) has a detrimental effect on stroke outcome. Biomarker-guided antibiotic treatment of patients at high risk for pneumonia may help to improve stroke outcome. Therefore, the investigators will evaluate whether intensified infection monitoring via Procalcitonin guiding an early standardized antibiotic treatment improves functional outcome after stroke compared with standard therapy based on current guidelines.

The purpose of this study is to investigate the Safety and Efficacy of Cilostazol in slowing down the progression of peripheral arterial disease (PAD) in ischemic stroke patients with PAD in Taiwan.

To determine the revascularization rate of the CE-marked Trevo device in large vessel occlusions in ischemic stroke patients. Revascularization, defined as at least TICI 2a in the vascular territory treated at end of the neuro interventional procedure.

RATIONALE: Elevation in pulsatility indices (PIs), measured by transcranial Doppler (TCD), has been postulated to reflect downstream increased vascular resistance caused by small-vessel disease (SVD). Small arterial vessels are a significant determinant of vascular resistance and PIs are elevated when SVD is present in the intracranial circulation. Cilostazol, a phosphodiesterase III inhibitor, has other non-antiplatelet effects, such as vasodilation and neuroprotective effect. It has been shown to be effective in the secondary prevention of stroke especially in the SVD and it may be related to the other non-antiplatelet effects of cilostazol. OBJECTIVES: In this study, we aim to investigate whether cilostazol affects the changes of PIs in patients with acute lacunar infarction using serial TCDs. Our hypothesis is that cilostazol has other non-antiplatelet effects such as vasodilation effect and may decrease the vascular resistance in patients with acute lacunar infarction. Hence, cilostazol will decrease the PIs in patients with acute lacunar infarction.

The purpose of this study is to evaluate the safety and tolerability of SA4503 in patients recovering from a recent stroke. Secondary, to evaluate the efficacy of SA4503 compared to placebo.

The objectives of this study are to assess the safety, tolerability and local tolerance, and to investigate the plasma levels and terminal elimination half life of MCI-186, and to review the routine clinical and neurological assessments data of MCI-186 in subjects with acute ischemic stroke.

We are doing this clinical trial in order to evaluate two different treatments for non-fluent aphasia: Melodic Intonation Therapy (MIT) and Speech Repetition Therapy (SRT). MIT uses a simple form of singing, while SRT uses intensive repetition of a set of words and phrases. We want to see which intensive form of treatment is more effective in leading to an improvement in speech output compared to a no-therapy control period, and whether either treatment can cause changes in brain activity during speaking and changes in brain structure. We will use a technique known as functional Magnetic Resonance Imaging (fMRI) to measure blood flow changes in the brain and structural MRI that assess brain anatomy and connections between brain regions. We will use fMRI to assess brain activity while a patient speaks, sings, and hums. We will assess changes in brain activity and in brain structure by comparing scans done prior to treatment to scans obtained after treatment and we will also examine changes between treatment groups. We will correlate changes in brain activity and brain structure with changes in language test scores.
