What Does Herpes Do To Your Brain?

Abstract. The development of the inflammatory response within the brain, meninges and cerebrospinal fluid (CSF) compartment has been studied for the first time simultaneously in experimental herpes simplex virus (HSV) encephalitis after inoculation via the cornea. Two major viral pathways were found from the eye to the brain: one through the trigeminal nerve to the brain stem and one through the . Typically, the virus is initially present in a part of the brain called the limbic cortex. It may then spread to the adjacent frontal and temporal lobes of the brain. It is the destruction of tissue in these areas together with brain swelling from the inflammation, which causes many of the symptoms.

General Discussion. Herpes simplex encephalitis (HSE) is a rare neurological disorder characterized by inflammation of the brain (encephalitis). Common symptoms include headaches, fevers, drowsiness, hyperactivity, and/or general weakness. The disorder may have some symptoms similar to those associated with meningitis, such as a stiff neck, altered reflexes, confusion, and/or speech abnormalities.

The development of the inflammatory response within the brain, meninges and cerebrospinal fluid CSF compartment has been studied for the first time simultaneously in experimental herpes simplex virus HSV encephalitis after inoculation via the cornea. Two major viral pathways were found from the eye to the brain: one through the trigeminal nerve to the brain stem and one through the nasolacrimal duct to the olfactory system. Viral antigen was found to be present in the CNS before there were clinical signs or cellular infiltration of brain tissue.

Subsequently, the virus spread to all parts of the trigeminal brain stem complex. This phenomenon was accompanied by severe inflammation of the meninges covering the trigeminal root near its entry into the brain stem. The meninges near the entry of the olfactory fila also contained antigen. However, HSV-1 did not spread along meningeal rami of the trigeminal nerve and, consequently, is--at least in this experimental model--not a route to reach the inferior frontal and temporal lobes.

The development of CSF changes followed the histopathological development of meningitis and encephalitis closely. We postulate that HSV is carried to the CSF by infected leukocytes rather than a direct spread to the CSF by simple extension of the encephalitic process to the meningeal surface.
