Filter by:Traumatic brain injury (TBI) caused by accidents is a very important public health problem in Taiwan. There are many people with brain damage and cognitive dysfunction caused by traumatic brain injury every year. Currently, there is no effective treatment for cognitive dysfunction caused by traumatic brain injury. Evidence from clinical studies in recent years suggests that hyperbaric oxygen therapy may be a treatment for repairing nerves after brain injury. Many studies have shown that oxidative stress and inflammatory responses play an important role in the pathogenesis of the central nervous system. In recent years, our research team has shown that oxidative stress and inflammatory response are significantly associated with the prognosis of patients with traumatic brain injury, cerebral hemorrhage, and stroke patients. More and more evidences also show that oxidative stress and inflammatory response play an important role in the neuropathological changes of mental cognitive sequelae after traumatic brain injury. This injury may be gradual from the time of head trauma. This process begins with the generation of oxidative stress and free radicals. When the cell repair and free radical scavenging system can not effectively overcome the excessive production of free radicals, an oxidative damage reaction will occur, causing a series of inflammatory cells and cytokines to be activated. Studies have also shown that when inhibiting those free radicals that produce oxidative stress, the neurological function and cognitive function of the head after trauma can be significantly improved. It is becoming widely acknowledged that the combined action of hyperoxia and hyperbaric pressure leads to significant improvement in tissue oxygenation while targeting both oxygenand pressure-sensitive genes, resulting in improved mitochondrial metabolism with anti-apoptotic and anti-inflammatory effects. The investigators published an article this year showing that hyperbaric oxygen therapy can improve the prognosis of patients with acute stroke and increase endothelial progenitor cells in the systemic circulation. The investigators plan to conduct this research project through hyperbaric oxygen therapy and neuropsychological therapy, and using scientific tests and neurocognitive function assessments. The investigators hope to answer the following questions: (1) Whether the treatment of hyperbaric oxygen can improve oxidative stress and inflammatory response after brain injury, and observe changes in biomarker concentration; (2) Whether hyperbaric oxygen therapy and neuropsychological therapy can improve cognitive function after brain injury; and (3) which biomarkers are factors that influence cognitive function prognosis.
A longitudinal study evaluating the predictive ability of near infrared spectroscopy to predict brain injury in infants with hypoxic ischemic encephalopathy. Data will be analyzed at two different time periods, at discharge and again at 2 years of age.
Transcranial Doppler is a noninvasive tool. Using velocity measurements and pulsatility index it allows the evaluation of cerebral haemodynamics. In patients presenting brain injury cerebral perfusion may be impaired. Indirect cerebral blood flow can be monitored and risk of neurological worsening can be detected using transcranial Doppler. Education and performance of emergency physicians must be evaluated on brain-injured patients because this tool is operator dependent. The main objective of this study is to estimate the average number of exams required to learn transcranial Doppler within junior emergency physicians with the achievement of their learning curve. We will perform a prospective, monocentric, observational study within the neurosurgical resuscitation department of Grenoble Alpes University Hospital.

In this preliminary study, we will examine the safety, tolerability, and feasibility of transcranial direct current stimulation (tDCS), in the setting of dosage escalation, as a candidate intervention for children with Acquired Brain Injury (ABI).
This study aims to determine the validity and safety of disparity driven vergence using a portable goggle system (I-PAS) using a pseudorandom ternary sequence of frequencies for testing.
This study aims to investigate the efficacy and tolerability of fMRI-targeted repetitive transcranial magnetic stimulation (rTMS) in the treatment of depressive symptoms in service members with a history of concussive traumatic brain injury (TBI). Up to ninety participants will be randomized to active or sham treatment. Participants randomized into the active group will receive 20 sessions of left-sided dorsolateral prefrontal cortex (DLFPC) high-frequency rTMS, followed by right-sided DLFPC low-frequency rTMS. The DLPFC treatment area will be identified by using individual subject-level resting state network estimation (Hacker et al., 2013). Participants randomized into the sham treatment group will receive 20 sham treatments designed to have similar sound and tactile sensation, without producing active treatment. Participants will also be asked to complete regular follow-up evaluations for up to a total of six follow-up sessions. Those who do not respond to the treatment will have the option to receive active treatment through this study regardless of group assignment to active or sham.
Synthetic MR Technologies has created a quantified imaging solution - SyMRI - to enable radiologists to acquire quantified images and always obtain the best contrast images. This study represents an attempt to assess the clinical utility of this software.
Symptoms resulting from mild/moderate trauma to the brain are as varied as the individuals who sustain them. The currently held belief is that the majority of healing and functional recovery occurs within the first two years post injury. A large proportion of individuals who sustain mild/moderate brain injuries (mTBIs) do not fully recover, and continue to experience symptoms well beyond two years post injury. Cognitive rehabilitation programs have been shown to be somewhat effective in helping mTBI patients regain some functionality in these executive domains. The purpose of the current study is to use an objective assessment of brain function to track changes during either a full-time or part-time holistic cognitive rehabilitation program, specifically the ABI Wellness (ABIW) program. The NeuroCatch Platform™ test will be used to assess brain functioning before, during and after 3 months in the ABIW program. The NeuroCatch Platform™ test uses electroencephalography (EEG) to measure event-related potential (ERP) signals produced by the brain, in response to an auditory stimulus. Three brain processes are examined with this test: Auditory sensation (ERP marker is the N100), Basic attention (ERP marker is the P300), and Cognitive processing (ERP marker is the N400).
