Herpes simplex can cause a benign lymphocytic meningitis in adults but usually produces a severe encephalitis in neonates. Progression may be slow or rapid with personality change, dementia, seizures, ataxia and death. In the UK, the most common virus to cause encephalitis is herpes simplex virus.

It occurs when the herpes simplex virus travels to the brain rather than moving through the body to the surface of the skin and producing its more common symptom, a cold sore. The disorder may have some symptoms similar to those associated with meningitis, such as a stiff neck, altered reflexes, confusion, and/or speech abnormalities. Herpes simplex encephalitis is caused by a virus known as herpes simplex virus (HSV).
The disease may also be caused by herpes virus type 2 (HSV2). This virus can be spread by sexual contact or from an infected mother to her baby during childbirth.

Because encephalitis involves one or more parts of the brain, however, those with the condition may develop personality changes, confusion, or other disturbing mental symptoms as well as poor muscle control and sensory impairment features that distinguish it from an ordinary flu.

The best way to avoid encephalitis is to prevent the illnesses that may lead to it.
Herpes simplex encephalitis (HSE) is an acute or subacute illness that causes both general and focal signs of cerebral dysfunction. Although the presence of fever, headache, behavioral changes, confusion, focal neurologic findings, and abnormal cerebrospinal fluid (CSF) findings are suggestive of HSE, no pathognomonic clinical findings reliably distinguish HSE from other neurologic disorders with similar presentations (see Workup). Patients The initial presentation may be mild or atypical in immunocompromised patients (eg, those with HIV infection or those receiving steroid therapy). Encephalitis is an inflammation (swelling) of the brain. Encephalitis is usually caused by a virus, but other things (including bacteria) can also cause it. Mosquitoes can carry encephalitis causing viruses. Common viruses, such as HSV (herpes simplex virus) or EBV (Epstein Barr virus). 2. A first outbreak of genital herpes may also involve symptoms of meningitis (headache, fever, and light avoidance) lasting for up to one week. Often referred to as cold sores or fever blisters, characteristic herpes lesions often appear around the mouth at times of illness, after sun or wind exposure, during menstruation, or with emotional stress. Symptoms of herpes encephalitis include headache, fever, seizures, behavioral changes, and memory loss.
