Filter by:Traumatic Brain Injury (TBI) is a serious public health problem due to its high mortality and morbidity rates, mainly affecting young adult males. Aggression to the prefrontal cortex, caused by an external physical force, responsible for anatomical injury and/or functional impairment, causes cognitive deficits with important consequences for the individual affected by the trauma and their caregivers. Therefore, rehabilitation is of utmost importance. The increase in pre-frontal cortical activation through training, activity-dependent stimulation and neuroplasticity, especially in the dorsolateral prefrontal cortex (DLPFC) is related to better performance in functional memory. In this context, Transcranial Direct Current Stimulation (tDCS), intended to drive neuroplastic changes in the brain, has been widely used to bring benefits to the cognitive function of individuals affected by various neurological conditions, including TBI by promoting neuroplasticity for critically involved cortical areas in the performance of tasks, culminating in cognitive benefits. In addition, studies have shown greater benefits when the technique is combined with cognitive training. Therefore, the objective of this parallel, randomized, double-blind, placebo-controlled clinical trial is to investigate the effect of tDCS applied on the dorsolateral prefrontal cortex and virtual reality cognitive training alone or in association with tDCS on cognitive function of individuals with severe chronic TBI.
This research aims to extend the application of spreading depolarization monitoring to non-surgical TBI patients, using intraparenchymal electrode arrays and scalp electroencephalography to detect depolarizations and develop less invasive monitoring methods.
Traumatic brain injury (TBI) is a severely disabling injury which affects 150-200 people per million annually. Increasing evidence suggests that TBI may be a major risk of dementia, Alzheimer's disease (AD) in particular. Postmortem evidence has shown that beta-amyloid (Aβ) deposits, one of the most validated pathological biomarkers of AD, are present in the brains of severe TBI patients. Although the underlying mechanisms remain unclear, the axonal injury may play a role. Imaging investigations have revealed Aβ density maps of TBI patients overlapped with those of AD patients, and increased Aβdensity not only associated with prolonged TBI duration but also associated with decreased white matter integrity. Hence, the increasing accumulation in Aβ due to TBI may contribute to the initiation of the pathological alterations seen in AD. Treatment of TBI may not only be of benefit for the injury itself but also act to block the pathological changes in AD. As a part of the clinical arm of the project, in this subproject investigators will conduct a single-blind, block-randomized clinical trial to investigate the efficacy of acupuncture in TBI. More specifically, investigators hypothesize that acupuncture intervention will elicit neuroprotective processes and thereby reduce axonal damage in TBI, manifested as (1) decreased plasma levels of Aβ peptide, tau, and glial fibrillary acidic protein (GFAP) and (2) increased white matter integrity after acupuncture. Ninety-six participants will be randomly allocated to the acupuncture intervention (verum acupuncture) or control group (sham acupuncture) in a 1:1 ratio. All participants will receive 20 minutes of acupuncture treatment twice a week for 2 weeks. A set of commonly used acupoints for TBI treatment will be manually stimulated every 10 minutes. The multi-modality magnetic resonance imaging (T1, T2, and diffusion tensor imaging) and blood sample will be taken before and after the acupuncture session to measure the white matter integrity in brain and plasma levels of Aβ peptide, tau, and GFAP, respectively. After integrate these data with other subprojects, we can provide synergic and integrative mechanisms of the effects of acupuncture on the risk of AD after TBI.
The current project will examine the impact of an emotional processing intervention on emotional processing abilities in a sample of 50 persons with moderate to severe TBI. Outcome will be assessed across 3 domains. We will document changes resulting from treatment: (1) in emotional processing tasks (2) in other areas of function including QOL, social functioning, mood and cognition that are also likely to be impacted (3) in brain structure and function. The examination of efficacy in the above three areas will further our knowledge of emotional processing deficits in TBI and more importantly, identify an effective means of treating such deficits.
Severe Trauma Brain Injury (TBIs) is a public health problem and monitoring of Intracranial Pressure (ICP) is a determinant key of it prognosis. Within the noninvasive methods to estimate the ICP, the measurement of intraocular pressure has been proposed because of its biological plausibility (proximity of the eye to the encephalic contend). Objective. Correlate intraocular pressure with ICP in children with TBIs and obtain their utility values.
The goal of this study is to determine whether the addition of aEEG to cEEG in clinical practice does in fact help PICU physicians detect subclinical seizures in this population.
To observe the effect of PEEP on CVP among patients with different respiratory compliance
The FBRI VTC Neuromotor Research Clinic was established and opened in May of 2013 to provide intensive therapeutic services to individuals with motor impairment secondary to neuromotor disorders. It is direct by Dr. Stephanie DeLuca and based on the principles surrounding ACQUIREc Therapy. ACQUIREc Therapy is an evidenced-based approach to pediatric constraint-induced movement therapy, which refers to a multi-component form of therapy that is focused on helping children who have asymmetric motor abilities between the two sides of the body. Historically, ACQUIREc Therapy has the unimpaired or less impaired upper extremity constrained (by a cast or a splint) while also receiving active therapy from a specially trained therapist who shapes new skills and functional activities with the child's more impaired upper extremity but who is also a licensed Occupational or Physical Therapist (OT/PT). Therapy dosages are high much higher than tradition OT or PT - often lasting many hours per day, up to 6 hours a day, 5 days a week, for 2-4 weeks. Investigators have developed further treatments based on the same principles of intensive services combined with behavior shaping for other areas of the body that are also affected by weakness (e.g., the leg and trunk) also, but which usually do not involve constraint. These have been more generally labeled ACQUIRE Therapy. All forms involve intensive, play-based therapy for children with asymmetric motor impairments of the arms and hands. The primary focus of treatment is to facilitate the acquisition of new motor skills in the child's weaker body parts through high levels of intensive therapy using scientifically-based behavioral guidelines. Therapy is also delivered in naturalistic environments. ACQUIREc Therapy as a treatment method has been tested in two randomized controlled trials, and a specific manual for its implementation has been developed. Dr. (s) Ramey and DeLuca previously founded a similar clinic, The Pediatric Neuromotor Research Clinic, at the University of Alabama at Birmingham where Dr. DeLuca directed the research clinic for 13 years and oversaw the implementation of the ACQUIREc Therapy treatment protocol in more than 400 cases. This research will involve analyzing and interpreting the clinical data of children going through clinical procedures at the FBRI VTC Neuromotor Research Clinic. All participation is voluntary and no children will denied services if families choose not to participate.
Preliminary evaluation of electrodes placed on the brain for recording brain activity and novel algorithms to determine cortical spreading depolarization foci of origination following severe traumatic brain injury requiring neurosurgical intervention.
The purpose of this two phase study is to evaluate comprehension by people with acquired brain injury. The phase 1 portion of the study will examine comprehension of narrative paragraphs under 3 conditions: (a) written text only, (b) auditory output only (i.e., synthetic speech - David voice) or combined written text and auditory output. The phase 2 portion of the study is to evaluate comprehension of sentences and paragraphs produced with computer generated (synthesized) speech and digitized natural speech after multiple exposures.
