Filter by:Elevated intracranial pressure is a dangerous and potentially fatal complication after traumatic brain injury. Hyperventilation is a medical intervention to reduce elevated intracranial pressure by inducing cerebral vasoconstriction, which might be associated to cerebral ischemia and hypoxia. The main hypothesis is that a moderate degree of hyperventilation is sufficient to reduce the intracranial pressure without inducing cerebral ischemia.
Blepharoptosis (incomplete opening of the eyelids) occurs because of a disruption in the normal agonist-antagonist neuro-muscular complex balance. An external device could restore eyelid movement. A newer class of permanent magnets made of alloys of neodymium (Nd), iron (Fe) and boron (B) might provide the technology needed to develop a feasible external magnetic device that could restore eyelid movement.
Traumatic Brain Injury (TBI)patients often suffer from loss of muscle strength in the hand and foot, decrease in coordination and high muscle tone (spasticity). In this study, investigators seek to compare how two different training programs can improve the coordination and symptoms of fatigue in individuals with movement deficits secondary to TBI. Using brain imaging, the study will also investigate changes in brain structure and activity associated with hand movement.
Phase 1 of the STIMPACT trial is an open label,dose-escalation,safety study of intravenous (IV) methylphenidate (MPH) therapy in patients with disorders of consciousness (DoC) caused by severe brain injuries. To be classified as having a DoC, a patient must be in a coma, vegetative state (VS), or minimally conscious state (MCS), as determined by behavioral assessment using the Coma Recovery Scale-Revised (CRS-R). Patients with DoC admitted to the intensive care unit (ICU) will be eligible for the study. A total of 10 patients with DoC will be enrolled in the Phase 1 study. Patients will receive escalating daily doses of IV MPH starting at 0.5 mg/kg, increasing stepwise to 1.0mg/kg and 2.0 mg/kg unless an adverse event (AE) necessitates dose de-escalation or a serious adverse event (SAE) necessitates that the patient stop participation in the study. Pharmacokinetics will be evaluated in selected patients with indwelling venous catheters or arterial catheters via serial serum measurements of MPH at each dose. The pharmacodynamic properties of IV MPH at each dose will be assessed by comparison of pre-versus post-dose EEG-based measures. The pharmacodynamic properties of the maximum tolerated dose will also be assessed by comparison of pre-versus post-dose resting state functional MRI (rs-fMRI) connectivity measures. Finally, we will test the association between structural connectivity of the ventral tegmental area (VTA), a dopaminergic brainstem nucleus that is believed to mediate MPH activation of the cerebral cortex, and EEG and rs-fMRI pharmacodynamic measures.
Unfavorable outcomes (UO) are seen in 15 to 20% of patients with mild traumatic brain injury (mTBI). Early identification of patients at risk for UO is crucial for suitable management to be initiated, increasing their chances for a return to a normal life. The investigators previously developed a diagnostic tool enabling early identification (8 to 21 days after the injury) of patients likely to develop UO. In the present study, the investigators examined the value and beneficial effects of early multidimensional management (MM) on prognosis. The investigators used a diagnostic tool to classify 221 mTBI patients as UO (97) or FO (favorable outcome) (124). Patients whose initial risk factors point to UO are at risk of developing post-concussion syndrome (PCS). UO patients were randomized into 2 groups: a group that underwent MM (cognitive-behavioral rehabilitation) (34) and a group with no specific management (46). At 6 months, these 2 groups were compared and the impact of MM on outcome was assessed. Among patients initially classified as FO (101), 95% had FO at 6 months and only 5 had PCS as defined by DSM-IV classification. Of the UO patients who received MM, 94% had no PCS 6 months after injury, whereas 52% of the UO patients who did not receive MM had persistent PCS. The effect of MM on the recovery of patients at 6 months, once adjusted for the main confounding factors, was statistically significant (p<0.001). These results show that the initiation of MM after early identification of at-risk mTBI patients can considerably improves their prognosis.
Traumatic brain injury (TBI) is the leading cause of death, disability and cognitive impairment in young people worldwide. The majority of the traumatic deaths in developed countries results directly from lesions in the central nervous system. Furthermore, due to the persistence of disabling effects of TBI for many years, personal and public costs of supporting survivors have to be taken in consideration. Many patients rescued by ICU treatment may have been severely disabled or vegetative because of trauma. These data suggest that, despite improvement in medical and surgical treatments, other factors related to trauma itself and to patient's condition could have an impact on the final outcome. Aim of the TBI-PRO project is to collect high quality clinical and epidemiological data and to describe the outcome of moderate-to-severe TBI in a local contest (Bergamo area, Italy).
Aim 1: To use magnetoencephalography (MEG) and magnetic resonance imaging (MRI) in Veterans and civilians with mild traumatic brain injury (mTBI) and sensory postconcussive symptoms (PCS) to demonstrate the mechanism of therapeutic benefit of HD-tDCS for sensory symptoms, as shown by reliable changes in the activity of the cognitive control network (CCN) and sensory system network (SSN) following stimulation; Aim 2: this intervention will result in long-term improvements in measures of executive function, depression/anxiety, and quality of life.
The overall aim of this project is to investigate the clinical utility of the Andago System, a CE certified mobile bodyweight supporting walking robot, in children with neuromotor disorders. Clinical utility encompasses practicability, acceptability, appropriateness, and accessibility. In this study, the investigators would like to investigate several aspects of clinical utility that belong to the first three components.
This study will establish the acceptability and feasibility of enrolling and retaining heavy drinking Veterans with mild traumatic brain injury (mTBI) in an 8-week, randomized cross-over design trial of active VR working memory retraining (WMR). This study will also seek to establish the efficacy of active VR-WMR to increase performance in executive function.
Introduction: Traumatic brain injury (TBI) is one of the major health and socioeconomic problems in the world. Immune-enhancing enteral formula has been proven to significantly reduce infection rate in TBI patient. One of the ingredients that can be used in immunonutrition formulas to reduce inflammation and oxidative stress is French maritime pine bark extract. Objective: The main objective of present study is surveying the effect of French maritime pine bark extract on the clinical, nutritional and inflammatory status of TBI patients as the first human study in the world. Method: this is double-blind, randomized controlled trial. Block randomization are used. Intervention group will receive French maritime pine bark extract supplement (OLIGOPIN) 150 mg for 10 days. Control group will receive placebo for the same duration. Inflammatory status (IL-6, IL- 1β, C-reactive protein) and oxidative stress status (Malondialdehyde, total antioxidant capacity), at the base line, at the 5th day and at the end of the study (10th day) are measured. APACHE ІІ (acute physiologic and chronic health evaluation II) for assessment of clinical status of patients and Nutric questionnaires for assessment of nutritional status filled out at the base line, 5th day and the end of study. SOFA (sequential organ failure assessment) questionnaire for assessment of organ failure filled out every other day. The mortality rate will be asked by phone within 28 days of the start of the intervention. Weight, body mass index and body composition at baseline, 5th day and 10th day of intervention are measured. All analyses will be conducted by initially assigned study arm in an intention-to-treat analysis. The data will be expressed as mean ± SD.
