A case study of the cognitive and behavioral deficits of temporal lobe damage in herpes simplex encephalitis

Herpes simplex viral encephalitis is a fairly common nonepidemic encephalitis which produces severe neurological sequelae in survivors. Most viral infections of the central nervous system produce diffuse damage, but the herpes simplex virus demonstrates a predilection for localization in the temporal and orbitofrontal regions of the brain. This case study illustrates the highly significant language difficulties, marked memory deficits, and propensity for physical aggression following temporal lobe damage brought about by herpes encephalitis, and presents the usefulness of a new diagnostic measure in delineating such a variable cognitive pattern.
