| Encephalitis, Varicella Zoster Encephalitis, Human Herpesvirus 3 | Herpes Zoster Encephalitis | Meningoencephalitis, Herpes Zoster | Varicella Encephalitis | Encephalitis, Herpes Zoster | Encephalitis, VZ Virus | Encephalitis, Varicella | Herpes Zoster Meningoencephalitis Inflammation of brain tissue caused by infection with the varicella-zoster virus (HERPESVIRUS 3, HUMAN). This condition is associated with immunocompromised states, including the ACQUIRED IMMUNODEFICIENCY SYNDROME. Pathologically, the virus tends to induce a vasculopathy and infect oligodendrocytes and ependymal cells, leading to CEREBRAL INFARCTION, multifocal regions of demyelination, and periventricular necrosis. Manifestations of varicella encephalitis usually occur 5-7 days after onset of HERPES ZOSTER and include HEADACHE; VOMITING; lethargy; focal neurologic deficits; FEVER; and COMA.
