WebGuillain-Barré syndrome (GBS) is also called acute inflammatory demyelinating polyradiculoneuropathy (AIDP). It is a neurological disorder in which the body's immune system attacks the peripheral nervous system, the part of the nervous system outside the brain and spinal cord. The onset of GBS can be quite sudden and unexpected and … WebMorphological and physiological studies demonstrate that demyelination constitutes a significant component of the pathology in compressive spinal cord injury. In many cases of spinal cord injury, a rim of demyelinated axons surrounds a central core of hemorrhagic necrosis. This provides a pathophysiological basis for "discomplete" spinal cord ... WebIn multiple sclerosis, demyelination of the CNS axons is associated with axonal injury and degeneration, which is now accepted as the major cause of neurological disability in the disease.
