traumatic brain injury (tbi) is an important cause of death and disability in young adults ,and may lead to physical disabilities and long-term cognitive, behavioral psychological and social defects. there is a lack of definite result about the effect of thyroid hormones after traumatic brain injury in the severity and no data about their effect on mortality of the injury. the aim of this study...

Traumatic brain injury (TBI) occurs suddenly and has damaging effects to the brain that are dependent on the severity of insult. Symptoms can be mild, moderate, or severe. Oxidative damage is associated with traumatic brain injury through reactive oxygen/nitrogen species production. One such species, peroxynitrite, is elevated in TBI brain tissue (Orihara et al. [2001] Forensic Sci. Int. 123:14...

traumatic brain injury (tbi) is a common injury leading to child disability and is associated with a variety of long-term cognitive, social, and behavioral dysfunctions. emotion perception (ep) starts up an integral part of social communication is critical to achieve developmentally appropriate goals. this skill, which emerges relatively early in development, is driven by increasing connectivit...

Although systemic cooling had recently been reported as effective in improving the neurological outcome after traumatic brain injury, several problems are associated with whole-body cooling. The present study was conducted to test the effectiveness of brain cooling without interference with the core temperature in rats after fluid percussion traumatic brain injury (TBI). Brain dialysates ischem...

This manuscript reports the results of two studies focusing on patients with mild Traumatic Brain Injury (TBI). The first assesses the validity of the Meyers Short Battery (MSB) of neuropsychological tests. The second study reports on the reliability of the MSB. The groups consisted of normal controls, depressed, chronic pain patients, and patients with mild TBI. Validity was assessed using a d...

A known-groups design was used to determine the classification accuracy of Wechsler Adult Intelligence Scale-III (WAIS-III) variables in detecting malingered neurocognitive dysfunction (MND) in traumatic brain injury (TBI). TBI patients were classified into the following groups: (a) mild TBI not-MND (n = 26), (b) mild TBI MND (n = 31), and (c) moderate/severe (M/S) TBI not-MND (n = 26). A sampl...

─We describe a computer model of intracranial pressure (ICP) dynamics that evaluates clinical treatment options for elevated ICP during traumatic brain injury (TBI). The model uses fluid volumes as primary state variables and explicitly models fluid flows as well as the resistance, compliance, and pressure associated with each intraand extracranial compartment (arteries and arterioles, capillar...

OBJECTIVE To describe the emergency department (ED) management of isolated mild traumatic brain injury (TBI) in the USA and to examine variation in care across age and insurance types. METHODS A secondary analysis of ED visits for isolated mild TBI in the National Hospital Ambulatory Medical Care Survey 1998-2000 was performed. Mild TBI was defined by International Classification of Diseases,...

OBJECTIVE To describe the prevalence and psychological correlates of traumatic brain injury (TBI) among injured male combatants in the Iraq conflict. PARTICIPANTS A total of 781 men injured during military combat between September 2004 and February 2005. MAIN OUTCOME MEASURES Mental health diagnosis (ICD-9 290-319), particularly posttraumatic stress disorder and mood/anxiety disorders, assi...

It is estimated that approximately 1.5 million Americans suffer a traumatic brain injury (TBI) every year, of which approximately 80% are considered mild injuries. Because symptoms caused by mild TBI last less than half an hour by definition and apparently resolve without treatment, the study of mild TBI is often neglected resulting in a significant knowledge gap for this wide-spread problem. I...
