What's herpes encephalitis?
Herpes simplex infection is a relatively common cause of meningo-encephalitis. This condition is frequently severe - it causes an acute necrotising encephalitis - and has a high mortality.
Herpes encephalitis is inflammation of the brain, causing a range of symptoms including headache, nausea, anxiety, depression, confusion, loss of co-ordination, memory loss and seizures. The condition may occur during the primary infection or as the result of activation of the virus lying dormant due to a previous infection. It may develop in apparently well children without skin lesions.
The outcome of this disease depends on early diagnosis and treatment. Acyclovir is administered empirically and attempts to establish the diagnosis made by examination of the cerebrospinal fluid after two weeks.
