Filter by:Following current standard-of-care, subjects data (brain pressure) will be recorded for 1 hour and include 10-minutes of data during which the subject recieves chest physiotherapy (CPT). The hypothesis is that CPT is not harmful to brain pressure.
We proposed to examine the effect of an aerobic exercise intervention on depression in persons with Traumatic Brain Injury (TBI). We will compare persons with chronic brain injury who are assigned to receive the exercise intervention with those in the control group to determine the effect of exercise on levels of depression and specific symptoms related to depression including anxiety, pain, sleep, and cognition. In addition, the effect of exercise on activity, participation level, and quality of life will be examined. HYPOTHESES: 1. Participation in an aerobic exercise intervention will decrease the severity of depression in persons with chronic TBI. 2. Participation in an aerobic exercise intervention will lead to improvements in negative symptoms associated with depression including anxiety, insomnia, pain, and impaired cognitive functioning. 3. Participation in an aerobic exercise intervention will be related to improvements in activity and participation for patients with TBI. 4. Participation in an aerobic exercise intervention will lead to improvements in perceptions of quality of life.
We hypothesize that the stroke volume variation measured using the commercially available LiDCO monitor provides a reasonable estimate of volume when compared to standard measures. This study will collate data that is already being collected by the bedside nurses.
Neurocritical ill patients are frequently transfused. Red blood cell transfusion (RBCT) in these patients has been associated with deleterious effects, including higher rates of nosocomial infections, multi-organ failure, and mortality. Therefore, it seems crucial to avoid any unnecessary RBCT. Most critically ill patients tolerate hemoglobin levels near 7 g/dL without an increase in morbidity or mortality rates. In this regard, a recent sub-analysis of TRICC trial has showed that TBI patients may tolerate hemoglobin levels as low as 7 g/dL, but other studies including neurocritical patients suggested that severe anemia may worsen clinical outcome. Therefore, optimal hemoglobin levels in neurocritical care patients remain largely unknown. Some textbooks and guidelines recommend to transfuse these patients to reach hemoglobin levels near to 10 g/dL, despite the lack of a solid scientific background supporting this target. Even though it has not been demonstrated, hemoglobin-based RBCT prescription could result in over- or under-transfusion in neurocritical patients. Alternatively, it has been suggested that more physiological transfusion triggers, using direct signals coming from the brain, will progressively replace arbitrary hemoglobin-based transfusion triggers in the neurocritical patients [65]. At the neurocritical units, patients are often monitored by using non-invasive methods, such as near infrared spectroscopy which indirectly measures regional cerebral oxygen saturation (rSO2). Changes in rSO2 values have been shown to directly correlate with changes in erythrocyte mass, thus increasing with RBCT and decreasing with blood losses. Moreover, rSO2 values also show a good correlation with clinical outcome and other variables which are often monitored in TBI patients. The purpose of this study is to ascertain as to whether rSO2 levels are more efficacious than conventional hemoglobin levels in guiding RBCT in patients admitted to a neurocritical care unit.
The purpose of the study is to determine whether familiar vocal stimulation, provided during coma recovery, improves outcomes for persons who are unconscious after severe TBI. The primary hypothesis is that unconscious persons who receive standard rehabilitation (SR) plus a high-dose of Familiar Voice stimulation (FVs) compared to unconscious persons who receive SR plus a sham stimulation (Sham Group) will demonstrate: 1. Significantly more neurobehavioral functioning post-intervention compared to pre-intervention. 2. Using Functional Magnetic Resonance Imaging (fMRI), significantly higher average measures of volumetric activity in the whole brain, middle temporal gyrus bilaterally, primary auditory area, bilateral pre-frontal cortex, hippocampus and/or the cerebellum post-intervention compared to pre-intervention.
The incidence of central auditory dysfunction in war fighters who are exposed to high-explosive blasts while serving in combat have not been clearly determined. The objectives of this study are to determine whether central auditory processing (CAP) disorders are associated with exposure to high-explosive blasts. This study will also examine the incidence, magnitude and timing of spontaneous recovery of CAP function from blast exposure. The information provided by this study will help guide clinicians in both the military and VA health care systems regarding the likelihood of central auditory processing disorders in soldiers returning from deployment and suggest some clinical rehabilitative strategies for the treatment of these patients with CAP deficits.
NEOBRAIN brings together small and medium sized enterprises (SMEs), industry and academic groups devoted to the diagnosis, management, and neuroprotection in newborns with perinatal brain damage. The focus of NEOBRAIN is to identify strategies prevention of brain damage mainly observed in preterm newborns. (Copy from www.neobrain.eu)
Context: Traumatic brain injury (TBI) is a common condition associated with significant long-term cognitive, behavioral, and functional morbidities. There are minimal controlled efficacy data of various acute rehabilitation intervention approaches. Objective: To determine the relative efficacy of two different acute TBI rehabilitation approaches - cognitive-didactic versus functional-experiential. Secondarily to determine relative efficacy for different patient subpopulations based on baseline cognitive functioning.
The purpose of this study is to evaluate brain injury when two different drugs (propofol and precedex) are used to sedate patients who need a neurologic exam.
Depression is very common in people who have experienced a traumatic brain injury. Few treatments have been found to be effective in treating depression in this situation. We intend to investigate the effectiveness of a form of brain stimulation, transcranial magnetic stimulation, which has been found to be effective in treating depression in people who have not undergone a brain injury. By evaluating new methods of treating depression in this population, we hope to increase the options available for treating people in this difficult situation. Furthermore, problems with aspects of thinking are also commonly present post brain injury, as in some individuals with depression. Various brain stimulation techniques, including transcranial magnetic stimulation (TMS) have been shown to have a positive effect on cognition. We also intend to investigate whether a therapeutic effect on cognitive deficits is present following TMS, in addition to any effects on depression. New treatment protocols will be developed, and understanding of the pathology and treatment of post traumatic brain injury depression will be enhanced.
