CCM Blood Biomarker Validation Study
Hemorrhagic StrokeIntracerebral1 moreCerebral cavernous malformations (CCMs), one of the most common microvascular malformations in the capillary beds of the brain, are susceptible to hemorrhagic stroke. As an autosomal dominant disorder with incomplete penetrance, the majority of CCM gene mutation carriers are largely asymptomatic but when symptoms occur, the disease has typically reached the stage of focal hemorrhage with irreversible brain damage. Currently, the invasive neurosurgery removal of CCM lesions is the only treatment option, despite the recurrence of the symptoms after surgery. Therefore, there is a grave need for prognostic/monitoring biomarkers as risk predictors for stroke prevention. The objective of the proposal is to develop a set of blood prognostic/monitoring biomarkers as precise risk indicators for stroke prevention. In this project, the plan is to validate the novel serum biomarkers identified in Ccms animal models and human CCMs patients, and utilize these biomarkers with statistical algorithms for risk prediction of hemorrhagic CCMs. This proposal has been formulated based on recent findings of five serum etiological biomarkers associated with disruption of the Blood-Brain Barrier (BBB), the first step for hemorrhagic CCMs in Ccm mice models. This work will lay the groundwork for larger human trials for final validation and revolutionary potential clinical applications.
Rehabilitation of Visual Function After Brain Injury
StrokeIschemic3 moreIn Denmark, about 120,000 people suffer from brain damage, of whom approx. 75,000 with brain damage after stroke. Serious and often lasting vision impairments affect 20% to 35% of people after stroke. Vision is the most important sense in humans, and even smaller permanent injuries can drastically reduce quality of life. Vision impairments after brain damage inhibits rehabilitation and enhances other invalidating effects. Reduced vision results in impaired balance, increased risk of serious falls, increased support needs, reduced quality of life, and impaired ability to perform activities of daily living. Restoration of visual field impairments occur only to a small extent during the first month after brain damage, and therefore the time window for spontaneous improvements is very limited. Hence, brain-impaired persons with visual impairment will most likely experience chronically impaired vision already 4 weeks after brain injury and the need for visual compensatory rehabilitation is substantial. Neuro Vision Technology (NVT) is an supervised training course where people with visual impairments are trained in compensatory techniques using special equipment. Through the NVT process, the individual's vision problems are carefully investigated and personal data is used to organize individual training sessions that practice the individual in coping with situations that cause problems in everyday life. The purpose of this study is to investigate whether rehabilitation with NVT can cause significant and lasting improvement in functional capacity in persons with chronic visual impairments after brain injury. Improving eyesight is expected to increase both physical and mental functioning, thus improving the quality of life. Participants included in the project will be investigated in terms of both visual and mental functions, including quality of life, cognition and depression. Such an investigation has not been performed previously and can have a significant impact on vision rehabilitation both nationally and internationally.
Remote Ischaemic Conditioning for Fatigue After Stroke
StrokeIschemic2 moreThis is a pilot randomised control trial to assess the safety, compliance, and acceptability of delivering a 6-week programme of remote ischaemic conditioning (RIC) to stroke patients suffering with fatigue, and study feasibility. A minimum of 34 patients who have suffered an ischeamic or haemorrhagic stroke and who suffer from fatigue, will be recruited and randomised to receive a 6-week programme of either RIC or a sham intervention.

Secondary objectives included to evaluate whether combined application of Xingnaojing injection and Naoxueshu oral liquid can promote hematoma absorption or reduce perihematoma cerebral edema in patients with intracerebral hemorrhage
Multicenter Study on the Efficacy of Transcranial Direct Current Stimulation (tDCS) in Post-stroke...
StrokeIschemic1 moreSeveral previous studies have used tDCS as a neuromodulation tool, showing improvements in several diseases (Lefaucheur et al., 2017). Based on these observations, it is believed that the use of tDCS in combination with specific motor training may provide the opportunity to induce behavioral improvements in patients with motor deficits. As shown in previous reports brain stimulation can, in fact, interact with the intrinsic ability of the brain to "repair" damaged brain functions, increasing the involvement of compensatory functional networks and thus inducing neuroplasticity. If these low-cost, easy-to-use stimulation techniques prove to be useful in improving motor deficits with long-term effects, the current study would open up new and interesting avenues in the field of neurorehabilitation. Given the potential long-lasting effects of tDCS, there is currently a growing interest in the clinical sector with the aim to reduce motor deficits in patients with brain injury. The most widely used protocols in stroke patients include the application of either anodal on the hypsilesional hemisphere or cathodal tDCS on the unaffected hemisphere (contralateral), so as to increase and decrease the excitability of the motor cortex, respectively (Nitsche and Paulus, 2001). The main objective of this study is to evaluate the effectiveness of transcranial direct current stimulation in enhancing the functional recovery of the upper limb of stroke patients after three weeks of neuromotor training and subsequent follow-up. The secondary objective is to evaluate the treatment effects on balance, gait, motor dexterity and disability, besides the functional recovery of the lower limb.
Progesterone in the Treatment of Acute Hemorrhagic Stroke
StrokeA large number of preclinical studies have confirmed that progesterone and its metabolites have strong neuroprotective effects. As a neuroprotective agent, progesterone has been effective in several animal models of nerve injury, suggesting that the drug has a wide range of neuroprotective effects. Pharmacodynamic studies have shown that some characteristic mechanisms of the action of the neurosteroid on brain injury and cerebral congestion include: prevention of inflammatory reaction and cell death (by inhibiting the activation of inflammatory cytokines and microglia); control of angiogenic brain edema (by reestablishing blood-brain barrier and regulating aquaporin-4 water transporter) and cytotoxic edema (by regulating Progesterone can also improve the neural dysfunction after cerebral hemorrhage, promote the regeneration and repair of damaged axons (activate PI3K / Akt pathway to inhibit the expression of RhoA), prevent the loss of Ca2 + caused by excitotoxicity and improve the survival rate of neurons. It was found that progesterone injection could reduce brain edema and promote the recovery of nerve function after brain injury.
Tranexamic Acid for Spontaneous Acute Cerebral Hemorrhage Trial
Stroke HemorrhagicIntracerebral HaemorrhageThis study aims to explore the effectiveness of tranexamic acid (also known as trans amine or TXA) in reducing hematoma expansion in patients with hemorrhagic stroke when given in the acute phase. METHODOLOGY This will be a Phase III, parallel-group double-blind randomised placebo control trial. Patients allocated to the control group will receive standard care for hemorrhagic stroke according to the 2015 American Heart Association guidelines. Patients allocated to the intervention group will receive, in addition to standard care, a loading dose of intravenous TXA 1gm within 3 hours of symptom onset followed by a 1gm maintenance dose over 8 hours. Timing and dosing are in accordance to previous established study protocols. Patients in the intervention group will only receive a single treatment course of TXA. Study subjects will be identified by either the on-duty clinicians from the Department of Neurosurgery of this institution or by the study investigators. Should the patient meet study eligibility criteria consent will be obtained either from the patient or from his/her next of kin. 1:1 block randomization will be performed by a remote internet randomization service by accessing a website. Patients allocated to the intervention arm will have 1gm of TXA added to 100ml of normal saline (0.9%) infused over 10 minutes as a loading dose. This is then followed by a maintenance dose of 1gm of TXA in 500ml of intravenous isotonic solution infused at 120mg/hour (60ml/hour) for 8 hours. Patient's allocated to the control arm will have an equal volume of normal saline (0.9%) infused as a placebo. The patient and the outcome assessor will be blinded to study group allocation. The primary endpoint of this study will be to assess the percentage change in brain blood clot volume by computed tomography brain scans on admission, 6 hours later, at 24 hours and at 1 week.
A Randomized Trial Comparing 2 Methods for Rapid Induction of Cooling in Stroke Patients, Cold Infusions...
Ischemic StrokeHemorrhagic StrokeMild hypothermia improves outcome in patients with global cerebral ischemia after cardiac arrest. Hypothermia seems promising also in other acute hypoxic-ischemic or in brain swelling associated cerebrovascular disease. The narrow-time-frame is a major issue ("time is brain"). To provide immediate cooling without delay, easy to use, mobile and effective methods are needed. Cold infusions (4 °C) are an accepted standard worldwide. EMCOOLS Flex.Pads (Emergency Medical Cooling Systems AG, Wien, Austria) is a new non-invasive surface cooling system. A comparison of these two induction methods has never been done before. Neither was the effect of EMCOOLS Flex.Pads on brain-temperature measured. For the first time iCOOL 2 compares feasibility, safety and efficacy of the two methods.
