Herpes simplex encephalitis (HSE) is a viral infection of the human central nervous system. HSE is thought to be caused by the retrograde transmission of virus from a peripheral site on the face following HSV-1 reactivation, along a nerve axon, to the brain.[1] The virus lies dormant in the ganglion of the trigeminal cranial nerve, but the reason for reactivation, and its pathway to gain access to the brain, remains unclear, though changes in the immune system caused by stress clearly play a role in animal models of the disease. Most individuals with HSE show a decrease in their level of consciousness and an altered mental state presenting as confusion, and changes in personality.
He suffered from an infection called herpesviral encephalitis which is extremely difficult to treat. This axial diffusion-weighted MR image shows high signal in the cortex of the temporal lobes and insula, much more marked on the right.
The majority of infections are caused by human herpesvirus 1 (herpesvirus 1, human) and less often by human herpesvirus 2 (herpesvirus 2, human).


The olfactory nerve may also be involved in HSE,[5] which may explain its predilection for the temporal lobes of the brain, as the olfactory nerve sends branches there. Increased numbers of white blood cells can be found in patient's cerebrospinal fluid, without the presence of pathogenic bacteria and fungi. The calculated apparent diffusion coefficient map (click image) confirms restricted cortical diffusion and shows increased diffusion in the underlying white matter. 57% of American adults are infected with HSV-1,[3] which is spread through droplets, casual contact, and sometimes sexual contact, though most infected people never have cold sores. In horses, a single-nucleotide polymorphism is sufficient to allow the virus to cause neurological disease;[6] but no similar mechanism has been found in humans.
The differential diagnoses include limbic encephalitis (paraneoplastic), gliomatosis cerebri, and status epilepticus. Pathologically, the condition is marked by a hemorrhagic necrosis involving the medial and inferior temporal lobe and orbital regions of the frontal lobe.
About 10% of cases of herpes encephalitis are due to HSV-2, which is typically spread through sexual contact. The electrical activity of the brain changes as the disease progresses, first showing abnormalities in one temporal lobe of the brain, which spread to the other temporal lobe 7a€“10 days later.[1] Imaging by CT or MRI shows characteristic changes in the temporal lobes (see Figure).

About 1 in 3 cases of HSE result from primary HSV-1 infection, predominantly occurring in individuals under the age of 18; 2 in 3 cases occur in seropositive persons, few of whom have history of recurrent orofacial herpes. Definite diagnosis requires testing of the cerebrospinal fluid (CSF) by a lumbar puncture (spinal tap) for presence of the virus. The testing takes several days to perform, and patients with suspected Herpes encephalitis should be treated with acyclovir immediately while waiting for test results. Other viruses can cause similar symptoms of encephalitis, though usually milder (human herpes virus-6, varicella zoster virus, Epstein-Barr, cytomegalovirus, coxsackievirus, etc.). In August 1999 a very rare and deadly case of herpes simplex type 1 was documented from South Africa. Patient master L.Naicker contracted this rare strain yet he survived and is the most notable recovery in history as he is still alive and on longterm anti-viral treatment.
