Filter by: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).
The purpose of this study is to investigate changes in response to robotic gait training in individuals with a traumatic brain injury.
Investigators will measure cerebrovascular reactivity (CVR) using functional near-infrared spectroscopy (fNIRS) and magnetic resonance imaging (MRI) during the chronic phase after repetitive mild traumatic brain injury (rmTBI) as a biomarker of traumatic cerebrovascular injury (TCVI). We hypothesize that CVR will be decreased in patients with rmTBI and that these decreases will correlate with clinical outcomes. Furthermore, we predict that 5 week administration of a phosphodiesterase 5 (PDE5) inhibitor, sildenafil citrate, will augment CVR in patients with a history rmTBI.
