Diffuse axonal injury (DAI) leads to disconnection of various brain regions, a condition which translates into much of the morbidity seen with head injury [1, 2, 3, 7, 8]. Following spinal cord injury (Table 2), damage to major white matter tracts disrupts sensory and motor circuits.

GENESIS OF AXONAL SWELLINGS IN TRAUMATIC INJURY
Alzheimer's & Dementia, 2023AbstractBackgroundAxonal swellings (AxS) are focal enlargements of axons found in a range of biological and pathological settings, including traumatic brain injury. However, the development of AxS and their early effects on axonal homeostasis are poorly understood.

Experimental Models of Traumatic Axonal Injury
Journal of Clinical Neuroscience, 2010Traumatic brain injury (TBI) is one of the leading causes of death in people under 45 years of age worldwide. Such injury is characterized by a wide spectrum of mechanisms of injury and pathologies. Traumatic axonal injury (TAI), originally described as diffuse axonal injury, is one of the most common pathological features of TBI and is thought to be ...

An axonal strain injury criterion for traumatic brain injury
Biomechanics and Modeling in Mechanobiology, 2011Computational models are often used as tools to study traumatic brain injury. The fidelity of such models depends on the incorporation of an appropriate level of structural detail, the accurate representation of the material behavior, and the use of an appropriate measure of injury.

Traumatic axonal injury in lambs: a model for paediatric axonal damage
Journal of Clinical Neuroscience, 1999Axonal injury (AI), an important determinant of clinical outcome after traumatic head injury in adults, has been little studied in child neurotrauma. In this experimental model, 10 anaesthetised, ventilated and physiologically monitored 4-5 week old lambs sustained a temporal impact to an unconstrained head. Examination of the brain 2 hours post-impact

Traumatic axonal injury, a clinical-pathological correlation
Journal of Forensic and Legal Medicine, 2017Traumatic axonal injury (TAI) is a distinct clinicopathological entity that can cause serious impairment of the brain function and can sometimes be found as a concrete cause of death. It has been discussed from the perspective of its biomechanical importance, and also from the standpoint of certain criteria for the pathological diagnosis of TAI ...

Traumatic injury of spinal axons
1995Abstract This chapter discusses the mechanisms of axonal loss and dysfunction in spinal cord injury. It focuses on the primary causes of axonal injury, the subsequent extracellular ionic derangements that occur at the injury site, and neurotransmitter-mediated secondary injury mechanisms.

Traumatic brain injury recapitulates developmental changes of axons
Progress in Neurobiology, 2022During development, half of brain white matter axons are maintained for growth, while the remainder undergo developmental axon degeneration. After traumatic brain injury (TBI), injured axons also appear to follow pathways leading to either degeneration or repair. These observations raise the intriguing, but unexamined possibility that TBI recapitulates

Traumatic axonal injury – an update
Pathology, 2011Diffuse axonal injury (DAI) was originally described in patients with diffuse brain injury and coma without a mass lesion and damage to axons in the cerebral hemispheres, corpus callosum, brainstem and cerebellum. Silver stains demonstrated the axonal changes in the white matter in fatal head injuries that occurred at least 12 hours prior to death. DAI

Detection of Functional Homotopy in Traumatic Axonal Injury
European Radiology, 2016This study aimed to explore the interhemispheric intrinsic connectivity in traumatic axonal injury (TAI) patients.Twenty-one patients with TAI (14 males, seven females; mean age, 38.71 ± 15.25 years) and 22 well-matched healthy controls (16 males, six females; mean age, 38.50 ± 13.82 years) were recruited, and from them we obtained resting-state fMRI ...
