Overview

Encephalitis is an acute inflammation of the brain, commonly caused by a viral infection. In patients with herpes simplex encephalitis, electroencephalograph may show sharp waves in one or both of the temporal lobes.

Other Diagnostic Studies

Electroencephalograph

In patients with herpes simplex encephalitis, electroencephalograph may show sharp waves in one or both of the temporal lobes called paroxysmal lateral epileptiform discharges. These waves are present even before changes can be picked by Ct scan or MRI and are positive in majority of cases. However, these are not diagnostic of encephalitis

Brain Biopsy

Highly specific and sensitive.
Rabies - Negri bodies in hippocampus and cerebellum
Cowdry type A inclusion with hemorrhagic necrosis in the temporal and frontal areas of brain - Herpes simplex virus.

 ==Overview==
-'''Encephalitis''' is an [[Acute (medical)|acute]] [[inflammation]] of the [[brain]], commonly caused by a [[virus|viral]] [[infection]]. Sometimes, encephalitis can result from a [[bacteria]]l infection, such as bacterial [[meningitis]], or it may be a complication of other infectious diseases like [[rabies]] (viral) or [[syphilis]] (bacterial). Certain [[parasitic]] or [[protozoa]]l infestations, such as [[toxoplasmosis]], [[malaria]], or [[primary amoebic meningoencephalitis]], can also cause encephalitis in people with [[immune deficiency|compromised]] [[immune system]]s. Brain damage occurs as the inflamed brain pushes against the skull, and can lead to death.
