Filter by:Traumatic Brain Injury (TBI) is a common injury in combat, terrorist attacks and sports such as football and hockey. Unnecessary delays in the diagnosis and treatment of brain damage in patients who can benefit from evacuation procedures can lead to worse brain injury, worse outcome and, sometimes, unnecessary death. However, there is no reliable and sensitive method for diagnosis of TBI severity in the field. In this study we will examine the feasibility of using this a multifocal chromatic pupillometer for monitoring TBI, by examining the pupillary response to multifocal chromatic stimuli in intracranial pressure (ICP)-monitored severe TBI patients. As control, normal subjects will be tested for pupillary responses using this device.
CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.
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 aim of this study is to determine the effects of an acute session of physical exercise on cognitive functioning and humor of traumatic brain injury patients and to investigate whether different cognitive responses can be achieved with different intensities of exercise (moderate and vigorous). The investigators hypothesize that while moderate intensity physical exercise may be beneficial to cognitive functioning, vigorous intensity may be detrimental to TBI patients, as physical fatigue may impair alertness and other higher cognitive functions.
This is a randomized, controlled clinical trial at three sites to determine the safety and preliminary efficacy of the study drug to treat severe head trauma (GCS 4-8). It is hypothesized that the drug may lower pressure in the brain, reduce mortality and the patient may have improved neurological function following treatment.
The aim of this study is to determine effect of proprioceptive stimulation with passive gait training on the cortical activity in patients with severe brain injury, demonstrated as changes in EEG (electroencephalogram)and ERP (Event Related Potentials). Hypotheses: 1) Proprioceptive stimulation increases EEG-frequency in patients with impaired consciousness due to severe brain injury. 2) Proprioceptive stimulation increases conductivity speed of the cognitive P300-component of ERP in patients with impaired consciousness due to severe brain injury.
Experimentally high dose of hyperoncotic human serum albumin improve neurological recovery after head injury reduce cerebral edema and normalize apparent diffusion coefficient of water after ischemia reperfusion. The main hypothesis is that early administration of hyperoncotic serum albumin is able to reduce intracranial pressure for several days after severe head injury and thus reduce mortality and morbidity.
OBJECTIVES: I. Determine the relationship of closed head injury (CHI) severity, focal brain lesions, and the age at injury to the development of working memory, inhibition, and metacognitive skills in children or adolescents with CHI of varying severity. II. Assess the development of working memory, inhibition, and metacognitive skills in relation to discourse functions, scholastic achievement, and adaptive behavior in these patients. III. Determine the relationship between impaired inhibition, metacognitive skills, and the emergence of psychiatric disorder in these patients.
