Filter by:We would like to ascertain the prevalence of hypopituitarism after combat-related TBI. This will lead to enhanced awareness, recognition, and treatment of hypopituitarism, which can have life-saving ramifications and enhance quality of life and rehabilitation efforts in our combat veterans.
The purpose of this pilot project is to determine whether using inertial sensors placed on the waist during routine clinical balance testing (i.e. Balance Error Scoring System) (BESS), will be a more immediate, objective, reliable and sensitive way to measure and quantify balance deficits in individuals with mild Traumatic Brain Injury (mTBI). The investigators are also trying to observe if the sensors can be used to detect balance recovery after a mTBI. The investigators hypothesis is that collegiate atheltes with mTBI injury will have different recovery periods between their cognitive testing(IMPACT) and their balance measures.
The purpose of the current pilot study will be to utilize implementation intentions to increase patient compliance with appointment attendance. Participants in the current study will be individuals referred for evaluation of their treatment needs. Experimental groups will create a simple induction consisting of "what/when/where" statements (implementation intentions) with the intention of increasing their rate of calling to schedule and subsequently attend appointments associated with their care. It is anticipated that participants who take an active role in their plan and utilize the implementation intention procedures will be more likely to make and attend the appointments suggested by their treating clinician. This pilot project will provide valuable initial data as to the potential effectiveness of a simple, cost-effective means of increasing appointment attendance. If successful, it could lead to cost savings and a decrease in the appointment wait time for people by increasing the utilization of available appointments.
The study is to investigate the efficacy and safety of autologous transplantation of adipose-derived mesenchymal stem cells in patients with the sequelae caused by severe brain injury.
Problems with attention are a common and debilitating consequence of brain injury. Studies show that poor attention is the number one predictor of poor cognitive functioning one year post-injury. This is due to the fact that attention is a necessary component of more complex cognitive functions such as learning & memory, multi-tasking and problem solving. In many cases, individuals may exhibit problems with spatial attention known as 'hemi-spatial neglect syndrome' or simply 'neglect'. Many studies now show that the processing machinery of the brain is plastic and remodeled throughout life by learning and experience, enabling the strengthening of cognitive skills or abilities. The investigators own research has shown that brief, daily computerized cognitive training that is sufficiently challenging, goal-directed and adaptive enables intact brain structures to restore balance in attention and compensate for disruptions in cognitive functioning.
The primary objective of this study is to evaluate the effects of plasticity-based, adaptive cognitive remediation on the cognitive abilities, functional status and quality of life of soldiers and veterans diagnosed with persistent post-concussive symptoms (PPCS) following a mild traumatic brain injury (mTBI, also referred to as a concussion, or blast exposure), as compared to a computer-based control.
Objective: In this study we will develop and apply imaging techniques to perform the first three-dimensional (3-D) measurements of brain biomechanics during mild head movement in healthy human subjects. Biomechanics is the application of mechanics, or the physical principles in action when force is applied to an object, to the anatomical structure and/or function of organisms. Such techniques will be invaluable for building computational models of brain biomechanics, understanding variability of brain biomechanics across individual characteristics, such as age and sex, and determining brain sub-structures at risk for damage when movement of the head is accelerated, such as during a traumatic event. Study Population: Measurements will be performed on 90 healthy men and women aged 18-65. Design: We will build upon the model pioneered by our collaborator, Dr. Philip Bayly. The model places a human subject in a magnetic resonance (MR) scanner with one of two head support units that allows a specific range of motion. Each head support is latched such that it can be released by the subject, and results in either a rotation of the head of approximately 30 degrees or a flexion-extension of the head of approximately 4 degrees. Although both supports are weighted so that the motion is repeatable if the subject is relaxed, the subject can easily counteract the weight. The resulting acceleration/deceleration is small (in the range of normal activities, such as turning one's head during swimming) and has been validated and used in other human investigations of brain biomechanics. The subject repeats the motion multiple times during the MR scan under their own volition and desired pace to measure motion of the head and brain. Outcome measures: This project is a pilot study evaluating the potential of extracting three-dimensional estimates of brain deformation, such as strain measurements, using MR imaging. A primary outcome of this project will be a fast MR acquisition sequence for measuring 3-D brain deformation. The sequence will be evaluated by applying the protocol to human subjects, followed by preliminary quantification of the reproducibility and stability of deformation measurements.
The hypothesis was that the implementation of a Safe Kids East Central brain injury prevention program targeting children and caregivers admitted to the Georgia Health Sciences University Children's Medical Center is feasible and that short-term treatment effects of injury prevention education on the child or adolescent and the caregiver will increase bicycle helmet use.
It is hypothesized that the long-term results of rehabilitation and subsequent aging after Brain Trauma depend on brain's premorbid anatomical (structural) and functional (cognitive, emotional) reserves. The purpose of this study are: 1. to determine whether such reserves exist. 2. to study their convergent and discriminant validity. 3. to study their characteristics.
This is a prospective, longitudinal cohort study to evaluate the associations between indices of brain structure and function (measured at baseline, as soon as possible after injury) and course of post-traumatic stress disorder (PTSD) symptoms. Subjects will be service members who have sustained mild traumatic brain injury (classified as either "impact-induced mTBI" or "blast-induced mTBI"; n = 100 completers) or an extracranial injury (ECI) with no evidence of traumatic brain injury (TBI) (n = 100 completers). Subjects will complete an assessment battery at baseline and 6 months later that includes (1) structural magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) derived from a 3-Tesla magnet; (2) event-related brain potentials (ERPs) derived from brain electrical activity; (3) neurocognitive tests; and (4) neurological soft signs (NSS). Specific indices of brain structure and function derived from these assessments are hypothesized to demonstrate a significant relationship with course of PTSD symptoms, which will be measured at baseline, 3 months, and 6 months.
