View clinical trials related to Cerebral Hemorrhage.
Filter by:MRI research Group in the Advanced Technology Center of the Sheba Medical Center has developed an innovative methodology based on leakage (extravasation) contrast agent that allows to map the entire brain with high resolution and high sensitivity to check and describe disorders BBB (blood brain barrier). The aim of the current study is to evaluate the feasibility of the BBB disruption detection method to predict delayed peri - hemorrhage edema.
In this pilot study the researchers will investigate efficacy of hypothermia in the early stage of treatment patients with primary intracerebral hemorrhage.
The purpose of this study is to evaluate the superiority of effect of the modified micro-invasive aspiration and drainage and conservative medical therapy in the treatment of ICH spontaneously hypertensive scientifically.
Periventricular leukomalacia (PVL) is one of the most common brain injuries that occur in preterm infants. Inflammation, hypoxia-ischemia, free oxygen radical formation and excitotoxicity are all known pathogenic mechanisms that mediate this injury. Erythropoietin (EPO) has been shown to be protective against hypoxic-ischemic and inflammatory injuries. During the past decade, recombinant human Epo (rhEpo) has been widely used in preterm infants to prevent or treat the anemia of prematurity, in general, rhEpo has been considered to be safe and well tolerated in preterm infants. EPO was considered not capable of passing through blood-brain-barrier at low dose. Evidence from animal experiments reveals that rhEpo must be given in high doses at the beginning or within a short (up to 6 hours), critical time period after the onset of brain injury to achieve a significant neuroprotective effect. A recent study using high-dose rhEpo (3000 U rhEpo/kg body weight at birth) for neuroprotection in very preterm infants revealed that no signs of adverse effects of early high-dose rhEpo treatment in very preterm infants were identified. Contrary to this, a recent study in PVL of a rat model revealed that using a low dose rhEpo (50-100 U/kg) was effective in the treatment of brain damage induced by hypoxia-ischemia and did not affect normal oligodendrocyte maturity. On this basis, the researchers intent to investigate (1) whether low-dose rhEpo (100 U/kg) or high-dose rhEpo (3,000 U/kg) given to very preterm infants (gestation age < 32 weeks) immediately after birth and subsequently during the first 2 days is safe and possesses neuroprotective properties;(2) whether there are gender differences in response to the hypoxia-ischemic insult and EPO treatment; (3)the pharmacokinetics of low dose and high dose rhEPO. Very preterm infants with gestational age of < 32 weeks and admitted to the NICU are eligible for enrollment.
The purpose of this study is to evaluate the superiority of effect of the modified micro-invasive aspiration and drainage and conservative medical therapy in the treatment of ICH spontaneously hypertensive scientifically.
The outcome of brain injury (physical or stroke) may be related to a brain electrical phenomenon known as Cortical Spreading Depression (CSD). This is a brief cessation of function in a local region of brain tissue. It has been hypothesized that CSD may occur after brain injury and may expand the damage to adjacent brain areas. Our aim is to detect CSD by means of intracranial electrodes in patients with brain injuries and asses how these events alter the outcome of the patients.
