Secondary brain injury occurs gradually and may involve an array of cellular processes. Neurobehavioral disconnection syndromes occur after lesions of selected fiber bundles 45. DAI is one of the most common and devastating types of traumatic brain injury and is a major cause of unconsciousness and persistent vegetative state after severe head trauma. Preservation of axons with no evidence of Wallerian degeneration inflammatory cellular reaction or demyelination is taken to indicate that axons may be relatively spared consistent with the degree of recovery in some cases. Some people with nerve damage also have serious muscle problems organ damage incontinence and sexual The peripheral nerves to the bladder can be altered by several disease processes.ġ54 Clinical manifestations include cerebellar motor.
Primary and secondary brain injury are ways to classify the injury processes that occur in brain injuryIn traumatic brain injury TBI primary brain injury occurs during the initial insult and results from displacement of the physical structures of the brain. Diffuse axonal injury DAI is a brain injury in which scattered lesions occur over a widespread area in white matter tracts as well as grey matter. Schematic Drawing Of Wallerian Degeneration Following Peripheral Nerve Download Scientific Diagram TENS is a method of electrical stimulation which primarily aims to provide a degree of symptomatic pain relief by exciting sensory nerves and thereby 3일 전 Sciatica pain is a type of. Wallerian degeneration Additional less-characterized forms of cellular catabolism take place in the nervous system such as Wallerian degeneration in which part of a neuron or axon degenerates without affecting the main cell body.
