These patients suck.
Especially if the pt's never been wacked out prior. Family freaks..want ct-scans, neurologists, eeg's, etc...and get them (rightly so!)...
work-up invariably negative.
"...umm, she's probably just confused because she's here..in the icu..ummm..and she's old.."
family thinks you and the doc's are retarded...
(ok, maybe thats a little far fetched..)
this usually happens to 70-90' year-olds (and up..) with 'old-aged brains'... (shrunken brain ct's ('age related atrophy', etc..)...which is unfortunately normal at advanced ages..)
but try to explain THAT to the family...
one of the main reasons i dislike neuro-type stuff.
This would be a good post for the Neuro-icu board..
