Did you know?
WebReactive gliosis Gliosis is a common parenchymal reaction in the CNS and, although indicative of a pathological process, it is entirely nonspecific. Fibrillary and especially gemistocytic gliosis may at times be difficult to distinguish from a low-grade infiltrating astrocytoma, especially in smears or small biopsies. WebGlial scar formation (gliosis) is a reactive cellular process involving astrogliosis that occurs after injury to the central nervous system. As with scarring in other organs and tissues, the glial scar is the body’s mechanism to protect and begin the healing process in the nervous system. Can gliosis cause seizures?
WebJul 30, 2004 · Reactive gliosis specifically referred to the accumulation of enlarged glial cells, notably microglia and astrocytes, appearing immediately after CNS injury has occurred. In contrast to glial reactivity, which suggests a largely passive response to injury; glial activation implies a more aggressive role in responding to activating stimuli ... WebThese changes in the white matter are predictors of a future risk of stroke, even after adjusting for the presence of vascular risk factors; decline in global cognitive performance, executive function, and processing speed; dementia (Alzheimer type, vascular, and mixed); and death, particularly due to cardiovascular causes.
WebGliosis is a nonspecific reactive change of glial cells in response to damage to the central nervous system. In most cases, gliosis involves the proliferation or hypertrophy of several different types of glial cells, including astrocytes, microglia, and oligodendrocytes.
