Hypothesis
Can mild mental status changes indicate herpes encephalitis?
Conclusion
Early recognition of herpes encephalitis can prevent serious morbidity.
Supporting Evidence
- HSV encephalitis is uncommon, with about 2 cases per 250,000 per year.
- Most cases are caused by HSV-1, with 10% caused by HSV-2.
- An MRI is abnormal in the majority of PCR-positive cases.
- PCR testing has a sensitivity of 98% and specificity of 94% for HSV detection in CSF.
- Untreated HSV encephalitis has a high case-fatality rate of around 70%.
- Timely treatment improves prognosis, but only 40-50% achieve full neurological recovery.
Takeaway
If someone seems confused for no clear reason, it might be a sign of a serious brain infection called herpes encephalitis, which needs quick treatment.
