| ==Overview==
| |
| | |
| ==Classification==
| |
| Based on the duration of symptoms, VZV encephalitis may be classified into either acute or chronic.
| |
| | |
| ==Pathophysiology==
| |
| The causative agent for VZV encephalitis is [[varicella zoster virus]] (VZV), a double-stranded [[DNA virus]] within the [[Herpesviridae ]] family of viruses. The [[immune system]] eventually eliminates the virus from most locations, but it remains dormant (or [[viral latency|latent]]) in the [[ganglion|ganglia]] adjacent to the [[spinal cord]] (called the [[dorsal root ganglion]]) or the ganglion semilunare (ganglion Gasseri) in the base of the skull.
| |
| | |
| ==Causes==
| |
| VZV encephalitis may be caused by either varicella ([[chickenpox]]) or herpes zoster ([[shingles]]).
