Filter by:Fibrinogen is a unique precursor of fibrin and cannot be compensated for by other coagulation factors. If plasma fibrinogen concentrations are insufficient, hemostatic clots cannot be formed with the appropriate firmness. In severe traumatic brain injury(TBI) patients, plasma fibrinogen concentrations decrease earlier and more frequently than other coagulation factors,predicting massive bleeding and death. The purpose of this study is to try early injection of fibrinogen concentrate in severe isolated traumatic brain injury and investigation the effect of it on post bleeding and complications.
This is a follow-up study for an ongoing open label trial conducted by the Sheppard Pratt-Lieber Research Institute utilizing the catechol-O-methyl-transferase (COMT) inhibitor Tolcapone to evaluate its effects on cognition and neuropsychiatric symptoms in patients with brain injuries (BI). In this study, investigators will conduct a double-blind, placebo-controlled clinical trial utilizing a crossover design to study the effects of two weeks of Tolcapone 200mg administered three times a day (total of 600mg/day) on cognitive performance. Physical, emotional, cognitive and social functioning will also be evaluated through participant and proxy report. The investigators are planning to randomize a total of 12 patients with a history of acquired brain injury (BI).
This study aims to develop and evaluate biomarkers using non-invasive optical coherence tomography (OCT) and OCT angiography (OCTA) as well as ultra-widefield (UWF) fundus photography to assess the structure and function of the retinal and choroidal microvasculature and structure in persons with mild cognitive impairment (MCI) and Alzheimer's Disease (AD), Parkinson's Disease (PD), or other neurodegenerative disease, diseases as outlined.
to examine the relationship between repeated concussions and late decline of brain function. In addition, all participants agreeing to participate in the study will be asked to will their brains to The Krembil Neuroscience Centre Concussion Project at the Toronto Western Hospital with the consent and full knowledge of their families and doctors. However, it is possible to participate in the research without agreeing to a brain donation. The Project Team is specifically attempting a clinical-MRI-brain tissue research analysis to determine the exact mechanism of the damage to brain tissue following repeated concussions. This condition is known as chronic traumatic encephalopathy (CTE), and shows an abnormal protein in the brain called tau-protein.
The aim of this research program is to 1) Evaluate potential problems with vision, inner ear-eye reflexes and deficits of processing eye information that occur following TBI; and 2) Evaluate treatment programs for individuals with eye and inner ear problems that persist for greater than 10 days following injury. This study will include 465 youth and young adults (aged 6-30 years old) who sustain a TBI of any severity. An initial evaluative phase using the best available technology to evaluate eye and inner ear function will be performed, and compared with typical tests that are used in the clinic. If symptoms and functional problems remain 10 days after injury, participants will be randomly placed into a treatment group (including eye movement, inner ear-eye reflex and attention exercises as per our pilot studies) or a control group (typical rehabilitation). Success will be measured in terms of return to sport (mild TBI), achievement of goals (moderate and severe TBI) and quality of life. It is expected that this program will inform clinical practice and future research leading to a treatment program in TBI that includes multiple components.
In this study, our objective is to determine the effect of two different nerve stimulation types in changing sleep architecture.
In Denmark, about 120,000 people suffer from brain damage, of whom approx. 75,000 with brain damage after stroke. Serious and often lasting vision impairments affect 20% to 35% of people after stroke. Vision is the most important sense in humans, and even smaller permanent injuries can drastically reduce quality of life. Vision impairments after brain damage inhibits rehabilitation and enhances other invalidating effects. Reduced vision results in impaired balance, increased risk of serious falls, increased support needs, reduced quality of life, and impaired ability to perform activities of daily living. Restoration of visual field impairments occur only to a small extent during the first month after brain damage, and therefore the time window for spontaneous improvements is very limited. Hence, brain-impaired persons with visual impairment will most likely experience chronically impaired vision already 4 weeks after brain injury and the need for visual compensatory rehabilitation is substantial. Neuro Vision Technology (NVT) is an supervised training course where people with visual impairments are trained in compensatory techniques using special equipment. Through the NVT process, the individual's vision problems are carefully investigated and personal data is used to organize individual training sessions that practice the individual in coping with situations that cause problems in everyday life. The purpose of this study is to investigate whether rehabilitation with NVT can cause significant and lasting improvement in functional capacity in persons with chronic visual impairments after brain injury. Improving eyesight is expected to increase both physical and mental functioning, thus improving the quality of life. Participants included in the project will be investigated in terms of both visual and mental functions, including quality of life, cognition and depression. Such an investigation has not been performed previously and can have a significant impact on vision rehabilitation both nationally and internationally.
The purpose of this study is to assess the safety and efficacy of daily morning exposure to colored light in patients receiving acute inpatient rehabilitation services for stroke, traumatic brain injury, or non-traumatic brain injury with sleep disturbances such as poor nighttime sleep and/or excessive daytime sleepiness.In a two-arm randomized placebo-controlled study with pre-exposure and post-exposure assessments, we are comparing the effects of daily morning exposure to either blue light or red light on objective sleep quality, subjective sleep quality, functional rehabilitation outcomes, cognitive symptoms, fatigue, and neurological symptoms.
This study evaluates the effect of a physical exercise + caregiver skills training on feelings of burden, mood, and biological markers of inflammation in persons who provide care for Veterans with a TBI or dementia. Half of the caregivers will participate in a balance and flexibility + caregiver skills training program, while the other half will participate in a moderate/high intensity aerobic and resistance + caregiver skills training program.
This prospective observational study is designed to investigate the relationship between brain temperature, axillary temperature, rectal temperature, and bladder temperature of postoperative patients with brain trauma, and the relationship between brain temperature and prognosis. This study is conducted based on the following important assumptions. First, brain temperature of postoperative patients with brain trauma should be higher than the axillary temperature, rectal temperature and bladder temperature. Second, the consistency of brain temperature and bladder temperature is better than the consistency of brain temperature and axillary temperature, as well as that of brain temperature and rectal temperature. Third, brain temperature can help clinicians to predict the prognosis of patients with brain trauma. Therefore, brain temperature monitoring is significant in postoperative intensive care and treatment of patients with brain trauma.
