Filter by:Spontaneous hyperventilation is common in severe traumatic brain injury patients and correlates closely with poor outcomes. How to treat this pathological condition remain unsolved. Remifentanil is a frequently used short-acting opioid, has the potent side-effect of dose-dependent respiratory inhibition. Specifically, it prolongs the expiratory time only and does not influence the respiratory drive. Among the safety range, the investigators will determine an ideal dose of remifentanil to maintain PaCO2 between 35 to 45 mmHg. The investigators will monitor the cerebral blood flow of the middle cerebral artery and the internal carotid artery to validate cerebral perfusion improvement.
21 healthy control participants will be recruited. On Day 1 they will complete reward-guided decision making tasks and questionnaires followed by a functional magnetic resonance imaging (fMRI) scan. On Days 2 and 3 they will receive repetitive transcranial magnetic stimulation (rTMS) targeting a specific part of the brain called the dorsal anterior cingulate cortex (dACC) or sham stimulation, and will then repeat a subset of the same decision making tasks and fMRI sequences. If brain stimulation modifies decision making and dACC activity, it could represent a novel way of treating patients with neural circuit deficits that impede motivated behavior. Of particular relevance to the current trial, this rTMS study will run in parallel with a study of apathy (i.e., diminished motivation) in patients with traumatic brain injury (TBI), with the goal of eventually leading to a patient-centered trial of rTMS treatment for this disruptive neuropsychiatric symptom.
This three-year randomized clinical trial will evaluate a behavioral intervention for caregivers of Veterans with traumatic brain injury (TBI) and Alzheimer's dementia or mixed Dementia (AD/MD) to reduce caregiver depression, anxiety and burden, and improve veterans' health management. The study will combine and deliver two award-winning behavioral interventions - REACH VA (Resources for Enhancing All Caregivers Health in Department of Veterans Affairs) and the DoD's Virtual Hope Box, which we call REACH Hope. Both REACH and Hope Box have evidence of effectiveness individually but have not been delivered together for caregivers supporting veterans with complex neurodegenerative diagnoses and health conditions. Our primary hypothesis is that REACH Hope will improve caregivers' quality of life as measured by reduced burden.
The aim of our study was to compare the recovery of smell in people suffering posttraumatic olfactory impairment following a systematic olfactory rehabilitation performed by occupational therapists to natural recovery in a control posttraumatic group of patients.
Acute brain injury due to traumatic brain injury (TBI), intracerebral haemorrhage (ICH), and aneurysmal subarachnoid haemorrhage (SAH) carries a high morbidity and mortality, in part due to the development of secondary brain injury. The mechanisms behind secondary brain injury are incompletely understood, but oxidative/nitrosative stress and disturbances in the metabolism of the vasodilator nitric oxide (NO) are believed to be involved. The aim of the present study is to characterise systemic changes in markers of oxidative/nitrosative stress and NO metabolism in the early phase after acute brain injury, and to examine their relationship to clinical course, neurological outcome, and mortality.
The purpose of the study is to determine whether administration of a prebiotic, inulin, can improve the symptom complex associated with traumatic brain injury and whether inulin administration can alter the bacteria that live in the gut.
One of the most important neurological consequences following Traumatic Brain Injury (TBI) is the development of post traumatic epilepsy (PTE). Nevertheless, there is still no effective therapeutic intervention to reduce the occurrence of PTE. In previous studies with animals models of epilepsy, the biperiden decreased the incidence and intensity of spontaneous epileptic seizures besides delaying their appearance. The aim of this study is the evaluation of biperiden as antiepileptogenic drug to prevent PTE and also the determination of side effects, evaluating its cost-effectiveness in patients with moderate and severe TBI.
The aim of this research is to evaluate the diagnostic concordance of ultra low-dose and standard dose reconstructed computed tomography acquisitions using the ADMIRE algorithm to search for intracranial lesions - both hemorrhagic and bone lesions - in trauma patients at the emergency department. The study will also evaluate the diagnostic performance of the two protocols, as well as the speed of image reading. For the first time, acquisitions ≤ 10 mGy (lower value than reported in the literature) will be performed with top-of-the-range scanners available in the emergency room to search for intracranial lesions. These scanners are equipped with the latest generation of ADMIRE iterative algorithms.
The NeurO2 study is a multicenter observational study looking at NIRS monitoring in neurocrocritically ill patients during the acute phase of care following an acute brain injury. The study is nested within the HEMOTION Trial and the SAHaRA Trial
This is a prospective, randomized, two-arm, controlled 30-day investigational pilot trial using the gammaCore Sapphire S non-invasive vagus nerve stimulation (nVNS) device + standard of care (SOC) in newly-hospitalized patients with mild-to-moderate traumatic brain injury (TBI) to prevent the progression towards immunokine storms, systemic inflammatory response syndrome (SIRS), severe respiratory distress, and requirement for invasive mechanical ventilation, and death, when compared to SOC alone (the control arm).
