Dear freind, welcome to HCM .
a well asked query indeed !
it lookjs like a seizure
with sympathetic overactivity, and post ictal
state like drowsiness
does she periodically get better?
does the MRI show an infarct/ diffusion restriction?
how long back was the onset of episode?
you can give iv midazolam
under preparedness, under competent medical supervision and see if it aborts the episodes, confirming the seizure. EEG may / may not show it.
pl. take a neuro consult, if you are not able to decide further.
pl. post the results and greater details of the entire illness and would be glad to revert back.
she should be in an ICU
