Filter by: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.
This study is designed to examine the effects of a wake-promoting agent (Modafinil) on working memory (WM) in persons with moderate to severe TBI utilizing a double blinded placebo controlled methodology. Our approach is to evaluate participants with BOLD fMRI and a limited neuropsychological battery to examine WM performance before and after pharmacological intervention. Hypotheses 1. Because increased cognitive effort (as a function of decreased efficiency after TBI) is presumed to underlie fMRI activation dispersion that is seen during central executive WM tasks, we anticipate an attenuation of cerebral activation in prefrontal cortex during pharmacological intervention with Modafinil when compared to placebo administration on the mPASAT and vigilance testing. 2. There will be a correlation between the decreased dispersion of the fMRI signal on scans and improvement in neuropsychological measures when individuals are on Modafinil that is not seen when they are taking placebo.
Objectives: Ketamine is an effective, short-acting anesthetic drug, which does not decrease blood pressure. It is widely stated that Ketamine increases intracranial pressure (ICP), which prevents its use in many emergency situations, specifically in patients with traumatic brain injury (TBI) and with increased ICP. Based on previous clinical experience, we hypothesized that Ketamine decreases – rather than increases – ICP. Methods: Prospective, controlled, clinical trial. Children with ICP monitoring will receive a single Ketamine dose (1-1.5 mg/kg) either for increased ICP and/or before a potentially distressing activity. Hemodynamic variables, ICP and cerebral perfusion pressure (CPP) will be recorded 1 minute before and every minute for 10 minutes following Ketamine administration (Before/after design).
The main goal of the present study is to challenge the hypothesis that blood- brain barrier disruption following brain injury increases the risk for long-term disability, development of brain dysfunction, epileptic seizures and neuroanatomical alterations.
The purpose of this study is to investigate the efficacy of an SSRI, sertraline for the use of post-concussive symptoms following a traumatic brain injury. the study also seeks to investigate the relationship between irritability and aggression and anosmia in individuals who have suffered a traumatic brian injury.
The proposal will assess the effectiveness of SRI treatment of anxiety following TBI. We hypothesize that participants will report significantly fewer and less severe anxiety symptoms after a 12-week course of citalopram than after a 12-week course of placebo.
Family caregivers of persons with traumatic brain injury (TBI) have long-term demands that tax their coping abilities and adversely affect their health and well-being. This project will test the effectiveness of a problem-solving training program tailored to the unique needs of family caregivers of persons with TBI. Over a 3-year period, family caregivers and their care recipients will be recruited and randomly assigned to a problem-solving intervention group (n=40 dyads) or a control group (n=40 dyads). Participants in the problem-solving intervention group will receive four face-to-face problem-solving training sessions and monthly telephone problem-solving sessions over the course of 1 year. Control group participants will receive a handbook of educational materials and a staff member will contact each control group participant monthly by telephone to review these materials and other informational needs. No problem-solving training will be provided to control participants throughout the year. Caregivers and care recipients will be assessed at four points during their participation: at the initial assessment, at 4 months, at 8 months, and at the completion of the 1-year participation period. All evaluations will be conducted in the participants' homes. Measures of problem-solving ability, caregiver burden, and adjustment (depression, health, satisfaction with life) will be collected. Structural equation modeling and other regression/inferential analyses will be used to determine the effects of problem solving on caregiver adjustment over time after taking into account care recipient adjustment and caregiver ethnicity. This project will: (1) demonstrate how specified physical and emotional outcomes of caregivers and care recipients are related to caregiver problem-solving abilities and how these relationships vary as a function of time; (2) evaluate the effectiveness of a community-based, problem-solving intervention that will be delivered to caregivers; and (3) identify caregivers and care recipients with TBI who are at risk for adverse emotional and health outcomes.
A randomised control trial of patients who have a severe brain injury to determine if patients who receive a standardised sensory stimulation program emerge earlier from a vegetative state. The experimental group would receive, in addition to their normal occuaptional therapy, sensory stimulation which would involve the daily application of stimulation to all five senses using the Sensory Modalities Assessment and Rehabilitation Technique (SMART).
