Filter by:To identify the changes in the brain following repeated sports-related concussion in men's football, women's soccer, and women's lacrosse college athletes by reviewing the findings of MRI studies that look at the structure of the brain and the appearance of the white matter at baseline, during the acute phase of a concussive injury, and upon completion of collegiate athletic play and correlate these findings with standard clinical measures.
Protective ventilation (association of a tidal volume < 8 ml/kg with a positive end expiratory pressure) is poorly used in severe brain-injured patients. Moreover, a systematic approach to extubation may decrease the rate of extubation failure and enhance outcomes of brain-injured patients. We hypothesized that medical education and implementation of an evidence-base care bundle associating protective ventilation and systemic approach to extubation can reduce the duration of mechanical ventilation in brain-injured patients.
Our overall goal in this proposed study is to describe the current prehospital trauma triage process for older adult (ageā„55) patients with suspected Traumatic Brain Injury (TBI), to identify the effect of certain medications (anticoagulants and platelet inhibitors) on TBI-related need for trauma center services, and to identify novel TBI screening strategies that are feasible for use in the prehospital setting.
Traumatic brain injury is an extremely common disease, it counts 50.000 deaths and 235.000 hospitalizations every year. Functional consequences of an acquired brain injury have a considerable impact on quality of lives of patients and care-givers with direct effects on balance, mobility and on psycho-social functions. Attention deficits are one of the most frequent and disabling consequences of severe brain injury. Within the wide spectrum of attentive problems, patients with traumatic brain injury frequently have shown difficulties in divided attention. Patients, care-givers and professionals frequently refer difficulties also in selective attention and vigilance as consequence of the trauma. It has been shown how these difficulties are tightly related with the missed return to work after two years from the injury. The hypothesis of this study is to investigate the feasibility of a rehabilitative protocol on gaming using the console Xbox and its efficacy in improving balance, mobility, risk of falling, attentive functions (selective and divided attention) in subjects which have had a traumatic brain injury at least 12 months before.
PURPOSE: The long-term goal of this line of research is to develop rational, biologically based evidence for the treatment of post-concussion syndrome (PCS) in children. The objective of this application is to examine the effect of melatonin on the symptoms of PCS and its neurobiology using integrated neurodiagnostic techniques in children. OVERVIEW: PCS is a constellation of clinical symptoms including physical (i.e. headaches), cognitive (i.e. memory), and behavioral disturbances. PCS is associated with significant morbidity in the child and his/her family), and yet there are no evidence-based medical treatments available. This suggests an urgent need to develop novel treatment options to improve outcomes for children suffering from PCS. Melatonin has several relevant mechanisms of action, and neuroprotective effects. Recent research suggests that the explanations for persistent PCS symptoms may be due to alterations in neurotransmissions and neuronal circuitry, particularly involving the dorsolateral prefrontal cortex (DLPFC). Investigators have two specific aims: 1. To determine if treatment with melatonin improves PCS in children following mild traumatic brain injury. Hypothesis: treatment of mTBI children with PCS with 3mg or 10mg of oral melatonin for 28 days will result in a decrease in PCS symptoms as compared with placebo. Effects will be dose-dependent and may be independent of sleep effects. Methods: A randomized double blind, placebo controlled trial (RCT); Outcome measure is a PCS symptom questionnaire. A subsequent RCT will then be performed using the optimal melatonin dose at a second centre. 2. To understand the neurophysiological mechanisms of paediatric PCS and assess any resultant effects of treatment with melatonin. Methods: A case-controlled study within the RCT, using functional MRI and Transcranial Magnetic Stimulation to investigate the neurophysiological properties of paediatric mTBI before and after treatment; Treatment groups from the RCT will be compared with two control groups: i) normal controls and ii) asymptomatic mTBI children. SIGNIFICANCE: This study has the potential to 1) provide a safe and effective treatment for PCS and 2) will provide valuable information about the neurophysiological properties of the brain associated with PCS following mTBI in children and how these change with symptom resolution.
There will be 200 participants, who aged 30 years or older with TBI in 1,5,10,15 years ago and GCS=13-15 will be recruited. Another group of 200 participants with the same age and gender and without TBI will be recruited as the controls. All of them will undergo AD8 questionnaire for dementia screening and APOE4 genotyping. Further CASI and CDR will be tested for the confirmation of dementia diagnosis for the individuals with AD8 scaore >/=2. 10 TBI with dementia, 20 TBI without dementia and 10 controls will be selected randomly for AV45 amylid PET study. There will also be 10 participants without traumatic brain injury and interested in this study, aged 55 years or older better.
Pediatric severe traumatic brain injury (TBI) is the leading cause of death and disability in children ages 1-14 years old. There are no effective therapies to treat secondary brain injury and the post-injury response of CNS apoptosis and neuroinflammation. This study is a follow-up trial from a previously performed Phase I trial that demonstrated the safety and potential CNS structural preservation effect of intravenous autologous bone marrow mononuclear cells (BMMNC) after severe TBI in children. (Cox, 2011) The study is designed as a prospective, randomized, placebo controlled, blinded Phase 2 safety/biological activity study. The investigators hope to determine the effect of intravenous infusion of autologous BMMNCs on brain structure and neurocognitive/functional outcomes after severe TBI in children.
This study will examine resting dopamine function as well as dopamine response in the brain as it interacts with medicines normally prescribed to subacute Traumatic Brain Injury (TBI) patients.
This study is designed to test the hypothesis that patients with Traumatic Brain Injury (TBI)treated with Hyperbaric (HBO) will show improvement in function and an increased blood flow as evidenced by single-photon emission computerized tomography (SPECT) scan. Improvement is evidenced by increase in number of pixels on SPECT Scan and increased brain metabolism. Improvement may also be identified via cognitive assessments administered by Jupiter Medical Center Research Department.
Angiogenesis is an important pathophysiological response to traumatic brain injury (TBI) and modulated by pro- and anti-angiogenic factors. Recent studies have suggested that endogenous angiogenesis inhibitor endostatin/collagen XVIII might play an important role in the secondary brain injury following TBI. The aim of this study was to investigate early changes in the concentrations of CSF endostatin/collagen XVIII after TBI and evaluated the relations of endostatin/collagen XVIII to injury severity and clinical outcome. Endostatin/collagen XVIII concentrations were measured serially for 1 week after hospitalization by using the enzyme linked immunosorbent assay method in the cerebrospinal fluid of 30 patients with TBI and a Glasgow Coma Scale score of 8 or less on admission. Comparative analysis were used to determine if its serial changes correlate with the GCS score and prognosis. Receiver operating characteristic curve was used to appraise the value of CSF endostatin/collagen XVIII levels in predicting the prognosis of patients with severe head injury.
