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
A new study has identified a potential link between Alzheimer’s disease and the herpes simplex virus-1 (HSV-1). The new research also found that tau protein in the brain, considered a hallmark ...

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.
Herpes simplex viruses can affect areas of skin exposed to contact with an infected person. An example of this is herpetic whitlow , which is a herpes infection on the fingers; it was commonly found on dental surgeon 's hands before the routine use of gloves when treating patients.
Herpes simplex virions. Sensory ganglia have been associated with infections from viruses like herpes simplex, which can exist in a dormant state within the ganglia for decades after the primary infection. [31] When the virus becomes reactivated, blisters on the skin and mucous membranes appear.
