Herpes simplex encephalitis; Other names: Herpes encephalitis, Herpesviral encephalitis: Coronal T2-weighted MR image shows high signal in the temporal lobes including hippocampal formations and parahippogampal gyrae, insulae, and right inferior frontal gyrus. A brain biopsy was performed and the histology was consistent with encephalitis. PCR ...
Encephalitis; MRI scan image shows high signal in the temporal lobes and right inferior frontal gyrus in someone with herpes simplex encephalitis. Specialty: Neurology, infectious disease: Symptoms: Headache, fever, confusion, stiff neck, vomiting [1] Complications: Seizures, trouble speaking, memory problems, problems hearing [1] Duration
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.

Illness, though much rarer, can also cause anterograde amnesia if it causes encephalitis, which is the inflammation of brain tissue. There are several types of encephalitis: one such is herpes simplex encephalitis (HSV), which, if left untreated, can lead to neurological deterioration. How HSV gains access to the brain is unknown.
Herpes simplex virus 1 (cold sores) and 2 (genital herpes) (HSV-1 and HSV-2), also known by their taxonomic names Human alphaherpesvirus 1 and Human alphaherpesvirus 2, are two members of the human Herpesviridae family, a set of viruses that produce viral infections in the majority of humans. [1] [2] Both HSV-1 and HSV-2 are very common and ...
Brain MRI is the mainstay of initial investigation pointing to limbic lobe pathology revealing increased T2 signal involving one or both temporal lobes in most cases. [ 22 ] [ 14 ] Serial MRI in LE starts as an acute disease with uni- or bilateral swollen temporomesial structures that are hyperintense on fluid attenuation inversion recovery and ...
Epilepsy of the mesial temporal lobe is associated with HHV-6 infection. Within this region of the brain exists three structures: the amygdala , hippocampus , and parahippocampal gyrus . Mesial temporal lobe epilepsy (MTLE) is the most common form of chronic epilepsy and its underlying mechanism is not fully understood.
