FEAR EXTINCTION AND INFRALIMBIC CORTEX IMPAIRMENT AFTER MILD TRAUMATIC BRAIN INJURY
Traumatic brain injury (TBI) is a leading cause of morbidity and disability, with mild TBI (concussions) representing over 80% of cases. Although often considered benign, mild TBI is associated with persistent neuropsychiatric conditions, including posttraumatic stress disorder, anxiety, and …

The synthesis of childhood traumatic burden and executive dysfunction in young adults
… young adulthood and the incidence of one or more Mild Traumatic Brain Injuries (mild-TBI) while accounting for psychosocial variables like childhood or adolescent trauma. The literature to date revealed there are indications of possible long-term consequences to adaptive functioning resulting from …

Visual Perception in Traumatic Brain Injury: Effects of Severity and Effort
… performance by Traumatic Brain Injury (TBI) patients. So far, this impact has been relatively well studied in attention and memory. However, this is not the case for visual perception functions. Thus, the goal of this study was to determine to what extent TBI severity affect visual …

Aberrant hippocampal neurogenesis contributes to learning and memory deficits in a mouse model of repetitive mild traumatic brain injury
… the effect of moderate traumatic brain injury (TBI) on neurogenesis and found learning and memory shortfalls correlated with limited neurogenic capacity. While there are no substantial changes after one mild TBI, research has yet to determine if neurogenesis contributes to the worsened cognitive …

Language Dysfunction in Traumatic Brain Injury While Controlling for Effort
… study included three traumatic brain injury (TBI) groups (good effort mild TBI, poor effort mild TBI, and good effort moderate/severe TBI) and two neurologic control groups (dementia and unilateral left hemisphere stroke). Language impairment was examined using the following measures: Wechsler …

Specialist Healthcare Services for Concussion/Mild Traumatic Brain Injury
Mild traumatic brain injuries (TBIs) affect over a million people in England and Wales annually. While most individuals recover spontaneously within days to weeks, a significant proportion experience persistent symptoms that last months to years after injury. These symptoms are complex and …

From Acute to Chronic: Outcomes and Diagnostics in Traumatic Brain Injury
Traumatic brain injury (TBI) is the most common neurological disorder worldwide and is a leading cause of morbidity and mortality. Despite growing evidence of its short- and long-term effects, even following a so called “mild” injury, understanding the intricate relationship between injury …

Magnetic resonance imaging and serum biomarkers of traumatic brain injury – methodological and clinical considerations
Traumatic brain injury (TBI) constitutes a major public health problem. The advent of collaborative neuro-imaging studies, advances in magnetic resonance imaging (MRI) and development of serum protein biomarkers have created an opportunity to gain new insights into the recovery after TBI. This …

A Multigroup Analysis of the Psychological Factors that Contribute to Persisting Working Attention Problems in Mild Traumatic Brain Injury and Chronic Pain
<p>A significant subset of mild traumatic brain injury (mild TBI) and chronic pain (CP) patients report, and sometimes show objective evidence of, persisting cognitive problems. Despite differences in injury mechanisms, there is considerable overlap in the types of persisting cognitive symptoms …

Neuropsychological functioning of OEF/OIF combat veterans with posttraumatic stress disorder
… OEF/OIF combat veterans with PTSD and a comorbid mild traumatic brain injury (TBI) significantly differed from those with uncomplicated PTSD across multiple tests of cognitive functioning. To accomplish this objective, the medical records and neuropsychological assessment data of 59 OEF/OIF combat …

The Effects of Blast-Induced Neurotrauma on Blood-Brain Barrier Permeability, Cell-Cell Junction Protein Levels and the Role of Peroxynitrite
… in emergency departments in the U.S.. While mild traumatic brain injury (TBI) is often not reported or treated it may still result in significant pathophysiological disruptions for the patient. As a result of the ongoing military Operation Iraqi Freedom (OIF) and Operation Enduring Freedom …

From Acute Injury to Chronic Disease: Exploring the Neurological Consequences of Mild Traumatic Brain Injury through Functional Neuroimaging
Traumatic brain injury (TBI) is a global health crisis, with incidence rates growing rapidly. Further, TBI is the leading cause of injury-related death and disability, with lifelong impacts on the individual and their families. Of increasing concern is mild TBI (mTBI), which is overexpressed in the …

The characterization of the anterograde and retrograde consequences of traumatic axonal injury in a mouse model of diffuse brain injury
… axonal injury (TAI) is a consistent feature of (TBI) and is responsible for much of its associated morbidity. TAI is now recognized to result from progressive/secondary axonal injury, though much remains unknown in regards to the pathobiology and the long-term consequences of axonal injury. TAI …

Working memory impairments in children and adolescents after traumatic brain injury
Traumatic brain injury (TBI) in children has been reported to result in deficits in a range of cognitive functions. Severity of injury, time since injury, and age at injury are some of the determinants of the range and extent of the cognitive deficits. Little prospective data exists on the extent …

Executive Dysfunction following Traumatic Brain Injury and Factors Related to Impairment
… reported following Traumatic Brain Injury (TBI) and are important for establishing functional impairments. Understanding the nature of executive dysfunction following TBI is often complicated by secondary factors that can impact measured ability. This study sought to clarify the persistent …

Cerebral Metabolic and Neuropsychological Outcomes Following Mild Traumatic Brain Injury
Traumatic brain injury (TBI) in adolescents and adults can result in cognitive, emotional, behavioral and neurological deficits that can persist more than a year after an injury. The current preliminary study used 3D magnetic resonance spectroscopic imaging (MRSI) and comprehensive …
-
Neuropsychological, Psychosocial, and Mood Outcomes Following Mild Traumatic Brain Injury
Traumatic brain injury (TBI) in adolescents and adults can result in cognitive, emotional, behavioral and neurological deficits that can persist more than a year after an injury. The aim of the current preliminary study was to use a comprehensive neuropsychological assessment to determine the …

In Vitro Remodeling of Extracellular Matrix Following Mild Traumatic Brain Injury
… individuals suffer from traumatic brain injury (TBI) leading to permanent disabilities and even death. Mild TBI (mTBI) is the most common form of TBI comprising about 80-90% of all occurrences. Following a CNS insult like an mTBI, astrocytes can undergo activation resulting in the transformation …

Differences in brain architecture during long-term recovery following mild traumatic brain injury
Mild TBI (mTBI) is brain trauma from an external impact with a loss of consciousness less than 30 minutes. mTBI results in several biopsychosocial impairments with pronounced cognitive deficits, thought to resolve within three months of injury. Previous research suggests that these impairments are …
