seizures; hallucinations; and altered levels of consciousness. Without early diagnosis and treatment, severe brain damage or even death may occur. Herpes simplex encephalitis is caused by a virus called the herpes simplex virus. Most cases are associated with herpes simplex virus type I (the cause of cold sores or fever blisters), although rare cases can be caused by herpes simplex virus type II (genital herpes). It is poorly understood why some people who are infected with herpes simplex virus develop herpes simplex encephalitis while others do not. Changes (mutations) in genes such as TLR3 and TRAF3 have been observed suggesting there may be a genetic component in some cases. Treatment consists of antiviral therapy.Herpes simplex encephalitis is a rare neurological condition that is characterized by inflammation of the brain (encephalitis).
