Brief Summary

Encephalitics is a serious condition in which the brain becomes inflamed (swollen). It usually happens as a direct result of virus, such as herpes simplex virus (HSV). HSV encephalitis is often treated with the drug acyclovir (an antiviral drug which slows the growth and spread of HSV in the body). Despite this however, around 2 out of every 3 people will have memory difficulties long term. Dexamethasone is a corticosteroid medication, which works by preventing the release of natural chemicals in the body which cause inflammation. It is possible that dexamethasone could help to reduce in swelling of the brain may improve the recovery of patients with HSV encephalitis. The aim of this study is to find out whether treatment with dexamethasone can improve long-term health outcomes in adults with HSV Encephalitis.

Outcome Measures

Primary Outcomes (1)

  • Calcul of verbal memory score

    The primary outcome is a verbal memory score as determined by the Wechsler Memory Scale (WMS-IV) Auditory Memory Index, at 6 months post randomisation.

    at 6 months post randomization

Secondary Outcomes (17)

  • Visual Memory Index assessed by the Wechsler Memory Scale

    6 months and 18 months post randomization

  • Processing Working Memory - assessed by the Wechsler Adult Intelligence Scale version IV

    6 months and 18 months post randomization

  • Higher executive function -assessed by Trail Making Test Parts A and B

    6 months and 18 months post randomization

  • Anxiety -assessed by self-completed Beck Anxiety Inventory

    6 months and 18 months post randomization

  • Depression -assessed by self-completed Beck Depression Inventory Inventory

    6 months and 18 months post randomization

  • +12 more secondary outcomes
