Their pathologic slices were restudied. RESULT: The causes of gliosis included cranial infection, specially infection caused by virus without distinct symptoms cerebral ischemia, brain injury, radiological treatment of brain. most cases showed symptoms of intracranial hypertension, 55.9% of the patients accompanied with epilepsy.
