This is a prospective, randomized, double-blind, and controlled clinical study to investigate the effects of DLBS1033 in conjunction with standard therapy compared to standard therapy alone in acute ischemic stroke patients. It is hypothesized that the improvement in functional outcomes as measured by NIHSS and BI as well as the improvement in haemostatic parameters as measured by thrombocyte aggregation test (TAT), fibrinogen, and d-dimer in DLBS group will be significantly greater than those in the control group.
It has been reported that stroke is the first cause of becoming bedridden, and its cumulative recurrence rate in 5 years is approximately 35%. There is a high probability that patients reduce or discontinue medications by self-determination, leading to a high risk of stroke recurrence in these patients. Comprehensive and long-term patient educations ameliorating their self-management are important making patients possible to be managed according to the guidelines for their risk factors. Using disease management programs created for each of risk factors according to clinical practice guidelines, the influence of those programs were evaluated for the prevention of stroke recurrence in this Disease Management Program Stroke Trial.
The primary aim of this Phase II trial is to determine whether it is sufficiently likely that CTX DP treatment at a dose level of 20 million cells improves the recovery in the use of the paretic arm in acute stroke patients to justify a subsequent larger prospectively controlled study. This study will evaluate the safety and efficacy of intracerebral CTX DP at a dose level of 20 million cells in patients with paresis of an arm following an ischaemic middle cerebral artery (MCA) stoke. Eligible patients will have no useful function of the paretic arm a minimum of 28 days after the ischaemic stroke (a modified NIH Stroke Scale (NIHSS) Motor Arm Score of 2, 3 or 4 for the affected arm).
Rationale The only proven therapy for acute stroke is tPA within 4.5 hours of symptom onset. This is the standard of care for patients presenting to our hospital within that time frame. Thrombolysis outside the 4.5 hour window is considered only on experimental or compassionate grounds. Tenecteplase (TNK) is a genetically modified variant of tPA that has many theoretical advantages in acute stroke. Studies show that systemic plasminogen activation is higher after tPA administration, relative to TNK and this is associated with an increased risk of bleeding events. Imaging cerebral blood flow (CBF) with MRI (perfusion weighted imaging-PWI) and CT perfusion (CTP) can be performed routinely with standard clinical scanners. Patients with evidence of large volumes of tissue with low CBF, that is also structurally intact, as demonstrated by either normal signal on Diffusion weighted imaging (DWI) or normal cerebral blood volume (CBV) are considered to have penumbral patterns. Patients with penumbral patterns appear to be the ideal candidates for thrombolytic therapy, regardless of time from onset. Study Hypotheses 1. The primary aim of this study is to demonstrate the feasibility and safety of TNK based thrombolysis in ischemic stroke patients presenting 4.5-24 hours after symptom onset. 2. It is hypothesized that treatment with TNK in patients with penumbral patterns will be associated with reperfusion, early neurological improvement and penumbral tissue salvage. Study Design The study is planned as an open label feasibility and safety study of acute treatment with TNK in ischemic stroke patients with penumbral patterns evident on advanced MRI or CT perfusion sequences. Study Outcomes The primary outcome of this study is a safety endpoint, specifically the frequency of symptomatic hemorrhagic transformation evident on MRI or CT images on 24 h or day 5 scans. The ECASS II system for rating hemorrhagic transformation will be applied to all GRE/SWI images Significance Current treatment paradigms have not permitted success of tPA to be extended beyond narrow and limiting therapeutic window of 4.5 hours. Clearly, more effective patient selection criteria are required. Penumbral imaging is biologically plausible, practical and has been shown to be predictive of outcome. Application of these imaging techniques to the acute stroke population is the most promising strategy for extending the therapeutic window and for introducing superior thrombolytic agents.
The present study aims to compare the relative therapeutic efficacy of prism adaptation therapy combined with real versus sham tDCS. The investigators will test the hypothesis that the magnitude and duration of neglect improvement will be increased when prism therapy is combined with real tDCS compared to sham tDCS. A second objective is to test whether individual differences in baseline clinical or brain imaging measures can predict: 1) neglect severity or 2) inter-individual differences in patients' therapeutic response. A third goal is to use brain imaging to characterize the patterns of neural change induced by the intervention to identify brain structures that mediate therapeutic response.
The objective of this study is to better characterize the mechanisms of action of fluoxetine in motor recovery and more specifically to identify the neurophysiological substrate underlying fluoxetine-induced motor recovery in stroke. In this study, the investigators propose to use transcranial magnetic stimulation (TMS) to assess the effect of a chronic treatment of fluoxetine on corticospinal excitability and integrity.
This research is a Randomized, double-blind, placebo-controlled, multicenter clinical study. Chinese subjects with Ischemic Stroke.
Patients with brain hemorrhage resulting from a ruptured aneurysm (SAH) are at risk of developing a condition called vasospasm, one or two weeks after their hemorrhage. This is a major cause of stroke and death following SAH. A special type of CT scan, called CT perfusion, analyzes regional blood flow in the brain. We hypothesize that CT perfusion scans performed on admission and day 6 post-hemorrhage will enable us to predict which patients will go on to develop vasospasm.
