Traumatic Axonal Injury

American Journal of Forensic Medicine & Pathology, 2020
Abstract A 17-year-old prisoner was found unconscious during a morning check. The previous night, he had been struck on the chin multiple times by one of the other inmates. The patient remained unconscious and eventually died after nearly 1.5 months of care.

Hypoglycaemia is a cause of axonal injury

Neuropathology and Applied Neurobiology, 2000
Axonal injury as demonstrated immunohistochemically is increasingly being recognized at post‐mortem in patients who have been unconscious, and in some cases the cause of the coma may not be immediately apparent. Considerations include microscopical diffuse traumatic axonal injury and axonal injury associated with a range of metabolic encephalopathies ...

Diffuse Axonal Injury by Assault

The American Journal of Forensic Medicine and Pathology, 1987
A case of diffuse axonal injury (DAI) by assault is reported. The majority of DAI cases documented have been due to traffic accidents and some due to falls from height. DAI is caused by angular or rotational acceleration of the victim's head. The condition is common and is the second most important head injury after subdural hematoma with regard to ...

Metabolic injury to axons and myelin

Experimental Neurology, 2013
CNS white matter, the collection of axons and supporting glia of the mammalian CNS, makes up close to 50% of the human brain by volume. Interruption of vital interconnects within this tissue, even over a short segment, often leads to serious morbidity in a broad range of neurological disorders.

Diffuse Axonal Injury in Head Injury: Definition, Diagnosis and Grading

Histopathology, 1989
Diffuse axonal injury is one of the most important types of brain damage that can occur as a result of non-missile head injury, and it may be very difficult to diagnose post mortem unless the pathologist knows precisely what he is looking for. Increasing

Focal axonal injury: the early axonal response to stretch

Journal of Neurocytology, 1991
The development of a model for axonal injury in the optic nerve of the guinea pig has allowed analysis of early morphological changes within damaged axons. We provide evidence that the initial site of damage after stretch is the nodes of Ranvier, some of which develop 'nodal blebs'.

Axonal injury in the optic nerve: a model simulating diffuse axonal injury in the brain

Journal of Neurosurgery, 1989
✓ A new model of traumatic axonal injury has been developed by causing a single, rapid, controlled elongation (tensile strain) in the optic nerve of the albino guinea pig. Electron microscopy demonstrates axonal swelling, axolemmal blebs, and accumulation of organelles identical to those seen in human and experimental brain injury.

A method to quantitate axonal injury

Neuropathology and Applied Neurobiology, 1991
The quantitation of diffuse axonal injury provides a more objective approach to the assessment of tissue damage in head injuries. The method designed in this study takes into account the anisotropy and structural inhomogeneity of the brain, and the distribution of lesions in diffuse axonal injury.

Axonal Injury in Head Injury

1983
A histological analysis of 324 unselected fatal head injuries disclosed axonal injury in the form of retraction balls in 100 cases: this was severe in 64 and mild in 36. It is suggested that axonal injury exists as a spectrum without there necessarily being selective involvement of the corpus callosum or the rostral brain stem, and that cases with mild

Diffuse axonal injury in a rugby player

Journal of Clinical Forensic Medicine, 1999
Sections of the cerebrum, cerebellum, and brain stem of a rugby player who died 15 hours after being tackled were stained using an immunoperoxidase technique to detect beta-amyloid protein. The sections of the pons showed axonal spheroids in the base, and those of the cerebellum showed axonal spheroids in deep white matter.
