1. Why the virus was not found in the tests?

2. Why the treatments are not working?

Yimeng was suspected to have viral encephalitis.
Serum and CSF virus test: virus nucleotide tests for CMV, EBV, ADV, HSV1, HSV2, HHV6, B19 were all
negative. Bacteria, tuberculosis and cryptociccus were not found in the CSF. Serum and CSF antibodies for
autoimmune encephalitis were all negative.
IgG Index was elevated, and several IgG bands could be seen in the CSF.
Yimeng was treated with acyclovir (anti-virus), mannitol (decrease the ICP), ziprasidone (anti-psychiatric
drug), methylprednisolone (anti-inflammation), andglutathione (protect liver function). However, Yimeng's
symptom didn't improve within half a month after admission.
Then Yimeng's parents started to doubt the diagnosis, and ask the doctor why the virus was not found in the
test and could it be misdiagnosed. What's the meaning of IgG index. The doctor explained to Yimeng's
parents and answered their question properly. Yimeng's parents said they would continue to be cooperative.
