===== Herpes simplex virus encephalitis  =====
[[Herpes simplex]] virus encephalitis (HSVE) is a neurological disorder which causes inflammation of the brain. Early symptoms include headache, fever, and drowsiness, but over time symptoms including diminished ability to speak, memory loss, and aphasia develop. HSVE can also cause category-specific semantic deficits to occur.<ref>{{Cite web|url=https://rarediseases.org/rare-diseases/encephalitis-herpes-simplex/|title=Encephalitis, Herpes Simplex|date=2009|website=National Organization for Rare Disorders}}</ref> When this happens, patients typically have temporal lobe damage that affects the medial and lateral cortex as well as the frontal lobe. Studies have also shown that patients with HSVE have a much higher incidence of category-specific semantic deficits than those with semantic dementia, though both cause a disruption of flow through the temporal lobe.<ref name=":2" />
