Filter by:The purpose of the study is to evaluate the physiological response to application of the Intrathoracic Pressure Regulator (ITPR) in patients with compromised cerebral circulation. The study will evaluate the physiological response to intrathoracic pressure regulation (IPR) therapy in hemodynamically stable patients with compromised cerebral circulation who are on ventilatory support.
The purpose of this study is to demonstrate proof of clinical concept that application of the Intrathoracic Pressure Regulator (ITPR) will result in an increase in Cerebral Perfusion Pressure (CPP) and a decrease in Intracranial Perfusion Pressure (ICP) in patients with head injury and elevated ICP, and to determine the optimal ventilation tidal volume (TV).

This study is designed to investigate factors that are associated with prolonged recovery from mild head injury. The investigators are particularly interested in defining the impact of anxiety related variables, such as health anxiety and anxiety sensitivity in the maintenance of symptoms. A further goal of the study is the evaluation of two treatment methods that have been proposed to be effective in reducing the impact of post concussion symptoms. The investigators hypothesize that a treatment which is directly focused on changing these anxiety related variables will be more effective than one that does not.
This study will examine the long-term outcome of brain injuries, the effects of treatment on outcome and the effects of brain injury on people s behavior and abilities. Men and women between 18 and 75 years of age who served in combat in the Iraq war may be eligible for this study. It will compare test results in those who sustained a traumatic penetrating or blast-related brain injury during combat with those who did not. Participants undergo the following procedures over a 5-day period of testing that lasts about 6 hours a day: - Medical history and physical examination. - Blood test for genetic analysis. - Electroencephalography (EEG) to measure the electrical activity of the brain. - MRI or CT scans of the brain to look at the structure and blood flow of the brain. - Functional near-infrared spectroscopy (fNIRS) to monitor blood flow in the front part of the brain blood by measuring changes in near-infrared light. - Neuropsychological testing, including questionnaires, pen-and-paper or computerized tests, and performance of simple actions to measure brain function, language, memory and other cognitive abilities..
