Epidemiology of Silent and Overt Strokes in Sickle Cell Disease
AnemiaSickle Cell4 moreSickle Cell Disease (SCD) is a rare disease occurring in an estimated 100,000 individuals, often poor and underserved, in the US. Silent and overt strokes contribute significantly to morbidity in adults with SCD, resulting in functional impairment, challenges with school and job performance, and premature death. Five NIH-funded randomized controlled trials have identified therapies to prevent silent and overt strokes in children with SCD, including monthly blood transfusion therapy (for preventing initial and recurrent strokes) and hydroxyurea (for preventing initial strokes). Despite the observation that at least 99% of children with SCD in high-income countries reach adulthood, and approximately 60% of adults will experience one or more strokes (~50% with silent strokes and ~10% with overt strokes), no stroke trials have established therapeutic approaches for adults with SCD. For adults with SCD, inadequate evidence-based guidelines exist for secondary stroke prevention strategies. Applying stroke prevention strategies in children may not be effective for stroke prevention in adults with SCD, particularly given the high rate of co-morbidities. Identifying subgroups of adults with SCD and higher incidence coupled with the contribution of established stroke risk factors in the general population (smoking, diabetes, obesity, renal disease) will provide the requisite data required for the first-ever phase III clinical trials focused on secondary stroke prevention in adults.
Melatonin in Acute Stroke
StrokeAcute1 moreThis study will measure Interleukin 6 (IL-6), a well-documented inflammatory biomarker that is increased in the acute phase of stroke, and to compare its levels after the administration of melatonin - a well-documented anti-inflammatory and anti-oxidant - that regulates circadian rhythm, which helps promote sleep.
Study of Cerebral Venous System in Acute Ischemic Stroke Patients Receiving Reperfusion Therapy...
StrokeCerebral Venous System1 moreThe VAST study is a single-center prospective observational study that enrolled individuals with acute ischemic stroke (AIS) within 24 hours onset. The patients will receive neurological examination, multimodal computed tomographic perfusion (CTP) or multimodal magnetic resonance perfusion (MRP) before reperfusion therapy. The hypoperfusion volume, ischemic core volume, brain edema, cerebral arterial collaterals will be evaluated on baseline brain image. The status of cerebral venous system (CVs) including superficial middle cerebral vein, vein of Labbe, vein of Trolard, Sphenoid sinus, thalamostriate vein, Internal cerebral vein, Rosenthal's vein will be evaluated in phases of reconstructed imaging from CTP/MRP. The investigators will explore the venous markers for prognosis of AIS patients who received reperfusion therapy, and find the role of venous system in reperfusion injury.
NuroSleeve Powered Brace & Stimulation System to Restore Arm Function
Neurologic DiseasesHemiparesis12 moreThe purpose of this study is to investigate if a person with weakness or paralysis in one or both arms, can use the NuroSleeve combined powered arm brace (orthosis) and muscle stimulation system to help restore movement in one arm sufficient to perform daily activities. This study could lead to the development of a product that could allow people with arm weakness or arm paralysis to use the NuroSleeve and similar devices to improve arm health and independent function.
Effects of Verb Network Strenghtening Treatment (VNeST) Via Telerehabilitation on Word Finding in...
AphasiaAnomia1 moreDespite evidence showing that speech and language intervention may improve language and communication abilities in people with acquired language disorders (aphasia), there is still need for evidence for which types of therapy are effective. Further, to improve accessibility of care, there is increasing need for evidence of intervention effects when therapy is provided online, via telerehabilitation. Therefore, the project aims at evaluating the effects of telerehabilitation with a specific speech-language therapy intervention for improving word-finding in individuals with aphasia due to stroke. The intervention Verb Network Strenghtening Treatment (VNeST) trains word finding at sentence level, and the treatment effect is expected to generalize to the production of connected speech.
Trendelenburg Position for Acute Anterior Circulation Ischemic Stroke With Large Artery Atherosclerosis...
StrokeAcute IschemicThe effect of head position as a nonpharmacological therapy on acute ischemic stroke (AIS) remains inconclusive. Recent HOPES2 (Head dOwn-Position for acutE moderate ischemic Stroke with large artery atherosclerosis) suggest the safety, feasibility, and potential benefit of the head-down position (HDP) in acute ischemic stroke. The current study aims to investigate the efficacy and safety of HDP in acute moderate ischemic stroke patients with large artery atherosclerosis.
Stroke-Card Registry
Ischemic StrokeTransient Ischemic AttackStroke is the second leading cause of death and one of the main contributors to disability. Patients who survive the acute phase of ischemic stroke and those with transient ischemic attack (TIA) are at high risk of subsequent vascular events. Importantly, recurrent strokes are associated with a higher social and economic impact, higher case fatality, and worse clinical outcome than first-ever strokes. The burden of post-stroke complications, residual deficits, and inadequate medical and psychosocial care all contribute to long-term disability and reduced quality of life in these patients. The Department of Neurology of the Medical University Innsbruck undertook the STROKE-CARD trial (NCT02156778) between 2014 and 2018 with follow-up until 2019 to evaluate the efficacy of the Post-Stroke disease-management program STROKE-CARD care. After implementation of STROKE-CARD care, the investigators aim to document the quality of post-stroke care and compare outcome parameters to historical cohorts and the change over time. Furthermore the investigators aim to gain a large data-resource for future research of biomarkers, disease mechanisms, prognosis and imaging mechanisms for R&D.
