Filter by: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.
evaluation of the effect of Propranolol versus propranolol and clonidine on decreasing sympathetic hyperactivity after moderate traumatic brain injury
Phase 2/3, randomized, double-blind, placebo-controlled, single-treatment, multicenter trial assessing the efficacy and safety of MYOBLOC for the treatment of upper limb spasticity in adults followed by an open-label extension safety trial.
The study tests the promising results of a previous study (GAIN 1.0) in a larger RCT (GAIN 2.0) which takes place in the municipalities of Central Denmark Region where citizens live their daily lives and whose health- and social care systems support citizens who experience persisting PCS.
The overall objective is to obtain an initial assessment of the value of using [18F]3F4AP for imaging demyelinating diseases such as traumatic brain injury (TBI), neurodegenerative diseases such as mild cognitive impairment (MCI) and Alzheimer's Disease (AD): - Aim 1) Assess the safety of [18F]3F4AP in healthy volunteers and subjects with traumatic brain injury (TBI) and neurocognitive impaired subjects (AD/MCI). Hypothesis 1: Administration of [18F]3F4AP will result in no changes in vitals or other adverse events. - Aim 2) Assess the radiation doses to the main organs in healthy volunteers. Hypothesis 2: the radiation doses to each organ will be comparable in all subjects and within the acceptable limits. - Aim 3) Assess the pharmacokinetics of a bolus infusion of [18F]3F4AP in humans including healthy volunteers and patients. Hypothesis 3: the pharmacokinetics of [18F]3F4AP at the whole brain level will be similar in controls, TBI and AD/MCI subjects. The kinetics in demyelinated lesions will be slower than in healthy areas. - Aim 4) Correlate MR images with [18F]3F4AP PET images. Hypothesis 4A: all the lesions seen on the MRI will show increased signal (VT or SUV) on the PET images. Hypothesis 4B: some of the lesions on the MRI will show increased signal (VT or SUV) on the PET but not all. - Aim 5) Correlate [18F]3F4AP PET signal with neuropsychological testing in people with TBI and AD/MCI. Hypothesis 5A: increased PET signal (VT or SUV) will correlate with impaired Mini Mental State Examination (MMSE).
Mental health problems frequently complicate recovery from mild traumatic brain injury (mTBI) but are under-recognized and under-treated. Our research program aims to identify evidence-based strategies for closing this knowledge-practice gap. Building on a successful pilot trial, the reseachers will evaluate the effectiveness of a clinical practice guideline implementation tool designed to support proactive management of mental health complications after mTBI in primary care.
This clinical trial will evaluate two non-surgical devices designed to improve eye lid opening for patients with severe Blepharoptosis (incomplete opening of the eyelids).
Every year, approximately 2 million people in the United States and 280,000 in Canada experience a mild traumatic brain injury/concussion. In patients with concussion, symptoms experienced following injury usually get better within 3 months. However, approximately 5-25% of people will experience symptoms beyond the 3 month period, characterized by persistent headaches, fatigue, insomnia, anxiety, depression, and thinking or concentration problems, which contribute to significant functional impairment. Chronic headache is the most common symptom following concussions. They can last beyond 5 years following injury, significantly impacting daily activities. To date, post-concussion symptoms have no known "cure". One potential approach to treating post-concussion symptoms may involve using drug-free interventions, such as neuromodulation therapy. This has the goal of restoring normal brain activity. Repetitive transcranial magnetic stimulation (rTMS) is one method currently being explored as a treatment option. TMS is a procedure where brain electrical activity is influenced by a magnetic field. Numerous studies using rTMS to treat other disorders, such as dementia, stroke, cerebral palsy, addictions, depression and anxiety, have shown much promise. The primary objective of this study is to determine whether rTMS treatment can significantly improve persistent post-concussion symptoms. A secondary objective is to explore the relationship between potential changes in brain function and clinical markers associated with rTMS treatment and how functional near-infrared spectroscopy (fNIRS), a neuroimaging technology, may be used to assess rTMS-treatment response.
Over-ground exoskeletons for gait rehabilitation are studied enough in people suffering spinal cord injury, and its clinical use is escalating in the industrialized countries. Nevertheless, studies on gait rehabilitation through exoskeletons in subjects with Pyramidal Hemisyndrome (PH) are recognized by GRADE as Low Quality of evidence. This interventional longitudinal pilot study is aimed to investigate the feasibility, clinical effects, and compliance (from the experienced therapists (Indego Specialists)' point of view) of using an over-ground wearable robotic system (Indego) for gait rehabilitation of people with PH in the clinical practice. Two substudies will be conducted with the following aims: to explore changes in the gait pattern and muscle activity following Indego-assisted gait rehabilitation through the kinematic gait analysis (in subjects able to walk) associated with surface electromyography (sEMG) of 4 muscle groups of the lower limbs; to identify prognostic factors for walking recovery, investigating also the effect of the treatment on functional connectivity through the electroencephalographic (EEG) analysis. In order to satisfy the study aims, 30 subjects with PH and walking impairment will be recruited and assessed both clinically and instrumentally (in case of substudies) at the beginning (T0) and the end (T1) of the treatment period.
Objective: This 3-year multisite RCT will determine the effectiveness of a targeted multidomain intervention (T-MD) (anxiety/mood, cognitive, migraine, ocular, vestibular; and sleep, autonomic) compared to usual care (behavioral management) in military-aged civilians with complex mTBI.
