So the protein level is high based solely on the invading lymphocytes? That and the borderline low glucose had me thinking bacterial.

But why does it have a preference for the temporal lobe I wonder????

@chaosawaits I think of LP labs this way: Bacteria eat CSF glucose (low CSF glucose) and poop it out as proteins (high CSF protein). Viruses don't eat CSF glucose (normal CSF glucose) and are composed of proteins (high CSF protein). Tho I did get this question wrong because the CSF glucose was annoyingly borderline... should've just gone with the buzzword

I agree with everything but normal glucose. Glucose here is NOT normal.
to quote wiki
"The glucose level in CSF is proportional to the blood glucose level and corresponds to 60-70% of the concentration in blood. Therefore, normal CSF glucose levels lie between 2.5 and 4.4 mmol/L (45โ80 mg/dL)."

NBME reference table gives normal CSF glucose to be 40-70 mg/dL. As far as I'm concerned, for the purposes of the exam the reference table is probably a better source than wiki.
