Filter by:The aim of the study is to evaluate the cortical excitability in the severe brain injured patients. We hypothesize that: 1. There is a continuous decrease in intracortical inhibition from healthy subjects to awake patients with severe brain injury, and to patients with impaired consciousness. 2. Decreased intracortical inhibition correlate with the degree of impairment assessed with the clinical scores in patients with severe brain injury.
Extensive research has shown that the big event that leads to the initiation of vasospasm is the release of oxyhemoglobin (blood breakdown product).Depletion of NO synthase (19,20,21) was also noted after SAH.CSF is produced from choroid plexus in the ventricle. If the SAH is too dense, the blood in the subarachnoid space will not easy to be washed out.
Dysregulation of autonomic nervous system is evident in patients with spontaneous intracranial hemorrhage. In this study, we utilize a non-invasive method (heart rate and blood pressure variability analysis to analyze the autonomic activities in this group of neurosurgical patients. Our aim is to determine the utility of this modality in risk stratification and outcome prediction in these patients.
The aim of this study is to determine effect of proprioceptive stimulation with passive gait training on the cortical activity in patients with severe brain injury, demonstrated as changes in EEG (electroencephalogram)and ERP (Event Related Potentials). Hypotheses: 1) Proprioceptive stimulation increases EEG-frequency in patients with impaired consciousness due to severe brain injury. 2) Proprioceptive stimulation increases conductivity speed of the cognitive P300-component of ERP in patients with impaired consciousness due to severe brain injury.
Strict glycemic control improves mortality and morbidity of patients admitted to the postoperative intensive care unit (ICU). The investigators would like to know if this therapy could improve the long term neurologic and cognitive outcomes of patients treated for acute subarachnoid hemorrhage with either a surgical or intravascular approach.
The purpose of our study is to verify wherever normothermia (achieved with diclofenac administration) may improve intracranial pressure control and may limit secondary cerebral damage thus positively influencing outcome in patients with acute cerebral damage admitted to ICU.
According to Morgan et. al. (J Neurosurg 101:1026-1029, 2004): bilirubin as a cerebrospinal fluid marker of sentinel subarachnoid hemorrhage: a preliminary report in pigs, we're going to test the hypothesis in the cerebrospinal fluid of spontaneous subarachnoid hemorrhage patients.
