About 90% of cases of herpes encephalitis are caused by herpes simplex virus-1 (HSV-1), the same virus that causes cold sores. According to a 2006 estimate, 57% of American adults were infected with HSV-1, [3] which is spread through droplets, casual contact and sometimes sexual contact, though most infected people never have cold sores.
Brain scan, done by MRI, can determine inflammation and differentiate from other possible causes. EEG, in monitoring brain activity, encephalitis will produce abnormal signal. Lumbar puncture (spinal tap), this helps determine via a test using the cerebral-spinal fluid, obtained from the lumbar region. Blood test; Urine analysis
For herpes simplex virus encephalitis, a CT scan may show low-density lesions in the temporal lobe. These lesions usually appear 3 to 5 days after the start of the infection. Japanese encephalitis often has distinct EEG patterns, including diffuse delta activity with spikes, diffuse continuous delta activity, and alpha coma activity.
Infections of the central nervous system (CNS) consist of infections primarily of the brain and spinal cord. They include mostly viral infections, less commonly bacterial infections, fungal infections, prion diseases and protozoan infections. Neonatal meningitis is a particular classification by age.
Herpes meningitis is inflammation of the meninges, the protective tissues surrounding the spinal cord and brain, [1] due to infection from viruses of the Herpesviridae family [2] - the most common amongst adults is HSV-2. [3] Symptoms are self-limiting over 2 weeks [4] with severe headache, nausea, vomiting, neck-stiffness, and photophobia. [5]

Not long after, the seizures started up again and the family was told that Caper would need a second surgery to remove more pieces of his brain. “The first surgery had a 60% chance of giving him ...
Neurotropic viruses that cause infection include Japanese Encephalitis, Venezuelan Equine Encephalitis, and California encephalitis viruses; polio, coxsackie, echo, mumps, measles, influenza and rabies, as well as diseases caused by members of the family Herpesviridae such as herpes simplex, varicella-zoster, Epstein–Barr, cytomegalovirus and HHV-6 viruses.
