Filter by: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.
This study is about arm and hand recovery after a stroke. The investigators are testing an experimental arm therapy called Accelerated Skill Acquisition Program (ASAP) which combines challenging, intensive and meaningful practice of tasks of the participant's choice compared to two standard types of therapy (usual and customary arm therapy totaling 30 hours and usual and customary arm therapy for a duration indicated on the therapy prescription). A second objective is to characterize current outpatient arm therapy (dosage & content) following stroke for individuals who are eligible for ICARE. Eligible candidates must have had a stroke affecting an arm within the last 106 days.
The study investigated the clinical efficacy and safety of a 10-day course of therapy with daily intravenous administration of 30mL Cerebrolysin based on a comparison with Placebo in patients with acute ischemic stroke. 1070 patients were randomized in this trial in 2 parallel groups, one receiving Cerebrolysin, the control group receiving Placebo. Study drug will be given once daily by intravenous infusion for 10 consecutive days. Acetylsalicylic acid will be given orally, once daily throughout the study duration of 90 days as basic treatment. The clinical observation period for each patient will be 3 months and will include six clinical evaluation visits at Baseline (day 1) and on study days 2, 5, 10, 30 and 90.
The STARR network registry consists of a 4 spoke 1 hub system. Which will consist of prospective collection, recording, and regular analysis of telestroke patient consultation and care data for the purpose of quality measure assessment and improvement and benchmarking against other national and international telestroke programs.
Randomized, control, open label, multicentre clinical study. The patient who are in accordance with subject inclusion and exclusion criteria will be randomized to A group: Routine treatment B group: Routine treatment+ Cilostazol; C group : Routine treatment + Probucol; D group: Routine treatment+ Cilostazol+ Probucol .
The plasma concentration of high-density lipoprotein (HDL) can have anti-inflammatory, anti-oxidative and anti-thrombotic effects in addition to being able to remove cholesterol from peripheral tissues for secretion via the liver. The investigators hypothesise that elevation of plasma HDLs will reduce the inflammatory response following removal of unstable atherosclerotic plaques in the carotid artery. Such plaques can cause strokes and there is great benefit from early surgical removal, however such surgical procedures involve significant risks to the patient. The investigators propose infusing HDL into patients prior to removal of their unstable carotid plaque and measuring the changes in inflammatory responses in comparison to a similar placebo controlled group of patients.
The objective of the study is to test the action of the amantadine, as DOPA-agonist, in a double blind cross-over trial, amantadine / placebo, on the verbal fluency of chronic post stroke aphasic patients.
STUDY QUESTIONS - What is the real prevalence of platelet "resistance" to aspirin during the acute phase of stroke and after 3 months, and 1 year, as measured using different platelet function tests? - Do all methods measure similar levels of resistance, or are some methods more sensitive than others? - Does this resistance result in a worse clinical prognosis? Is this result independent of other variables? OBJECTIVES 1. Hospital Phase (Acute Stroke) - Determination, using various methods, of the prevalence of platelet hyperreactivity in patients treated with aspirin to treat ischemic stroke (acute phase) - Comparison of different assessment methods and identification of the most accurate of these - Identification of variables that correlate with platelet hyperreactivity 2. Follow-up Phase - Correlation between platelet hyperreactivity and important clinical outcomes at 12, 24, and 36 months - Correlation between platelet hyperreactivity and death or dependency at hospital discharge, at 3, 12, 24, and 36 months (Modified Rankin Scale) - Correlation between platelet hyperreactivity and recurrent stroke of any type - Correlation between different methods for evaluating platelet functions and identification of the most accurate method - Analysis of hyperreactivity over time THE STUDY - The study will include 200 consecutive patients seen in the emergency department of a large, urban hospital (1500 inpatient beds) and diagnosed with stroke in the acute phase; these patients will be treated with aspirin for an undetermined period - The investigators will not include patients who require full anticoagulation treatment, regardless of the cause - Importantly, the analysis of primary and secondary outcomes will be carried out after blinding the examiner to the results of the platelet aggregation tests PLATELET TESTS - Whole Blood Aggregometer, ChronoLog - VerifyNow, Accumetrics - PFA-100, Siemens - Plateletworks, Helena - Impact-R, Diamed - Serum thromboxane B2
The multi-center, double-blind, placebo-controlled, randomized, group-comparison study was designated to assess the long-term safety and efficacy of the antiplatelet drug cilostazol in preventing the recurrence of cerebral infarction in patients who had suffered a cerebral infarction 1 to 6 months prior to entering the trial.
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.
