Reactive<unk>  is a spectrum of changes in astrocytes that occur in response to all forms of CNS injury and disease. Changes due to reactive<unk>  vary with the severity of the CNS insult along a graduated continuum of progressive alterations in molecular expression, progressive cellular hypertrophy, proliferation and scar formation. Insults to neurons in the central nervous system caused by infection, trauma, ischemia, stroke, recurring seizures, autoimmune responses, or other neurodegenerative diseases may cause reactive astrocytes. When the<unk>  is pathological itself, instead of a normal response to a pathological problem, it is referred to as astrocytopathy.
