hey cuts, i'm going straight adult neuro (i was slightly interested in the combined program due to research interests in functional neuroimaging, but i can do that from adult neuro as well)
re Marchiafava-Bignami disease: just some zebra that a neuroradiologist at my institution loves to bring up (he brought it up each time i read w/ him, which was twice and separated by months). i think it's interesting as i love red wine so much.
as far as combined residency vs. one or the other: i'm not inclined to do a combined residency as i think it doesn't give enough exposure in each field. but this is also coming from a person who also considered the combined neuro/psych and neuro/im residencies.
re earnings potential: not something i'm particularly concerned about... i'll be comfortable whatever i do (how much money can one actually spend in a lifetime?). but carrigallen is right, you're not going to make *nearly* as much money as a neurologist as you would as a radiologist (esp an IR/INR).
An individual who is double boarded in rad/neuro may not have the equivalent experience that a rad/inr would have.
but the PDs of the programs would argue that the converse (or is it inverse?) is also true, that a rad/inr may not have the breadth of knowledge and skills that a rad/neuro/inr would. (e.g. while the rads resident spent x months doing RUQ ultrasounds, the neuro/rads resident was diagnosing acute stroke in the ER).
what i say: do one or the other, and see what peaks your interest during residency. unless you're absolutely sure that neurorads/INR is what you want to do, the combined residency would lock you into a decision that you may regret later (as i understand it, you won't be eligible for board certification in either field until you complete the entire seven years, ugh)...
clinical correlation is required
