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.
The present observational study is aimed at reporting the short-, mid- and long-term outcomes of patients with Disorder of Consciousness (DOC), in Vegetative State (VS) or Minimally Conscious State (MCS), due to a severe Acquired Brain Injury (sABI), after repeated treatments with anodal Transcranial Direct Current Stimulation (tDCS) on Left Dorsolateral Prefrontal Cortex (L-DLPFC), to stimulate recovery of consciousness. The results obtained will also be compared with those of a historical control cohort, before the introduction of tDCS, matched for demographic and clinical characteristics.
This is a double-blind, randomized controlled trial comparing the effect of omega-3 fatty acid versus placebo on blood biomarkers of brain injury, inflammation and neurogenesis.
Mild Traumatic Brain Injury (mTBI), including concussion, is a real public health problem. Indeed mTBI might induce long-term brain disorders with increased risk of neurodegenerative diseases and the healthcare costs can be significant for both the individual and the society. However mTBI is called the "silent epidemic", because of the lack of research in this field in France as well as in the rest of the world. Most of the time, mTBI is associated with sports injuries, road traffic accidents and falls. The risk of neurodegenerative diseases is significantly increased with the repetition of mTBI, which may have a cumulative effect. In this context, playing football (or 'soccer') is associated with a high risk of concussion and with frequent head-ball contacts which are repeated during the training and matches. Moreover, football is the most popular team sport in the world, with more than 265 million players. The long-term impact of "heading" in football is still debated in the literature. Nevertheless, several studies suggest the possible emergence of early neurocognitive disorders. Otherwise, while mTBI is usually characterized by normal brain images using traditional neuroimaging techniques, microscopic anatomical changes might be detectable by new neuroimaging techniques. According to recent studies, cognitive dysfunctions could be based on these microstructural changes in the gray matter and white matter, secondary to the primary mechanical injury. Studies that have examined the structural changes in the brain white matter in football players are rare and lack of evidence regarding the consequences of accumulated brain impacts explains the lack of preventive measures in this sport. In addition, post-traumatic secondary lesions cause functional alterations of the neurovascular unit and its effect on cerebral perfusion may play a crucial role, which has never been yet explored in humans over the long term. In this research, the investigators will develop a unique multi-modal neuroimaging protocols to assess brain changes after minor head trauma and over the time. Investigators want to perform magnetic resonance imaging (MRI) to assess cerebral blood flow using Arteria Spin Labelling (ASL), structural changes using Diffusion Tensor Imaging (DTI), susceptibility weighted imaging (SWI), and functional changes using BOLD resting-functional MRI.
Due its high incidence, mTBI and its consequences of PPCS are a major public health issue. There is no consensus regarding the treatment of PPCS in pediatrics. Relying on its results in adults, HBOT offers a promising new direction of treatment, which targets the basic pathological processes responsible for post-concussion symptoms. The effect of hyperbaric oxygen therapy in pediatric TBI has never been evaluated. The aim of the current study is to evaluate in a prospective cross-over, randomized study, the effect of HBOT on children with PPCS due to mild TBI.
The main goal of this study is to quantitatively assess the sucking and feeding activity of infants at high risk of neurological impairment (preterm infants and term infants at risk of abnormal neurodevelopment) during oral sucking and feeding and correlate it with their underlying neurological impairment for the early diagnosis of brain injury.
Decompressive craniectomy is frequently used to treat increased intracranial pressure or an intracranial mass effect. Trephined Syndrome describes a neurological deterioration, which is attributed to a large craniectomy. The symptomatology is varied but includes headache, aggravation of a hemisyndrome or cognitive disorders, often has an orthostatic component and improves or disappears with cranioplasty. The incidence of Trephined Syndrome has been reported between 7% and 26%. However, it might be underestimated if the course of cognitive functions before and after cranioplasty were insufficiently documented.
Prospective cohort study. Any patient with potential cerebral injured (medical or traumatic) will be included in the study, regardless of its severity, history, the presence of anticoagulant or antiagrégant. The collection should be done as soon as possible, in the reception of vital emergencies or in the urgencies. The collection consists of the realization of a Glasgow score and a scale of Kremlin-Bicêtre for all patients by completing a standardized collection sheet. The collection of GCS and Kremlin-Bicêtre must be did at the same time. The collection sheet is filled by medical personnel trained. The future of the patient is informed at 6 months using the Glasgow Outcome Scale- Extended, which will be made during a following consultation or by phone. Additional data will be collected on the folder (ventilation time, days of hospitalization, mortality).
This study will compare different polarities of transcutaneous spinal direct current stimulation combined with robotic-assisted arm training (RAT) in adults with acquired brain injury (ABI). Participants will receive 20 minutes of 2.5 milliamps (mA) anodal, cathodal, and sham transpinal direct current stimulation (tsDCS) over cervical spine combined with high intensity robotic-assisted arm training, five days a week, for 2 consecutive weeks.
