Herpes Simplex Encephalitis

Herpes Simplex Encephalitis is a rare but serious brain infection caused by the herpes simplex virus, which is better known for cold sores. After initial infection, the virus can stay dormant and reactivate, sometimes reaching the brain. This causes inflammation and damage, leading to symptoms like fever, headache, confusion, seizures, and changes in behavior or consciousness. Prompt treatment with antiviral medications, especially acyclovir, can improve outcomes. Early diagnosis is crucial, as untreated cases may result in severe brain damage or death.
