WebA reactive gliosis is seen around the plaques and tangles of Alzheimer’s Disease, which takes the form of reactive astrocytes strongly expressing GFAP, usually with hypertrophied and activated microglia. A gliosis is also associated with some other neurodegenerative diseases such as Huntington’s disease, but not usually with Parkinson’s disease. WebGliosis, also called astrocytic gliosis or astrocytosis, is a common term that refers to the reactive astrocytic response to a brain injury or insult. Almost all brain lesions have a component of gliosis, even with different glial pathologies. Gliosis is a secondary event to CNS damage and may persist for weeks or months after brain injury.
