Summary
Herpes simplex virus encephalitis (HSVE) often leads to permanent paralysis and severe disability, with high mortality. Early diagnosis of HSVE is crucial for potentially improving patient outcomes.
Area of Science:
- Neurology
- Infectious Diseases
- Virology
Background:
- Herpes simplex virus encephalitis (HSVE) is a severe neurological condition.
- The long-term sequelae and mortality rates of HSVE require further investigation.
Purpose of the Study:
- To evaluate the long-term clinical course and outcomes of patients with biopsy-proven HSVE.
- To identify factors influencing prognosis in HSVE.
Main Methods:
- A retrospective follow-up study of 15 patients with brain biopsy-proven HSVE.
- Clinical data and patient outcomes were assessed over a 6 to 67-month period.
Main Results:
- Mortality rate was 53.3%.
- Of the survivors, 93.3% experienced permanent paralysis or severe neurological deficits, often progressing from an initial reversible confusional state.
- Convulsive disorders were frequently temporary, unlike paralysis and coma.
Conclusions:
- HSVE has a high mortality and leads to severe long-term disability in most survivors.
- Timely and definitive diagnosis upon hospital admission may significantly alter the prognosis of HSVE.
- Prompt intervention strategies are critical for improving outcomes in herpes simplex virus encephalitis.
