Managing aggression in global amnesia following herpes simplex virus encephalitis: The case of E.B.

Abstract Aim: This article describes an integrative approach to the case of EB, a 33 year old male who presented with agitation, delusional ideation and global amnesia after contracting herpes simplex virus encephalitis (HSVE) while in a state prison in 2004. Case study: Although several prior case studies have described outcome following acute onset of HSVE, this case presents a unique challenge for rehabilitation in several respects. First, EB’s pre-morbid history is complicated; in contrast with prior HSVE case studies that have typically involved individuals with a relatively high level of pre-morbid functioning, EB presents with limited educational attainment and a prior history of several incarcerations for violent offenses. Post-injury, his presentation includes significant verbal aggression, threats of harm toward others, physical posturing and occasional physical aggression toward his caretakers. Third, EB presents with a fixed delusion that others are constantly taking advantage of him. These features are present in the context of global amnesia and relatively intact cognitive functioning in other domains. Following a brief review of prior HSVE case studies, this study reviews the outcomes of various pharmacological, cognitive, behavioural and integrative interventions designed for management of EB’s aggression and agitation.
