Hey there, I already listed a few of those in a recent thread. If you’re looking for programs that take neurology residents for NIR, there are plenty. It’s pretty easy to combine a stroke and NIR fellowship at these places. Good programs would be UPMC, UMiami.
However, if you’re look for “strictly combined” fellowships- and the only reason I can think of is if you’re on a J1 visa and don’t want the hassle of possibly terrible visa changes (country dependent) while going from stroke to NIR- then there’s only a few- JFK, U of Minnesota are two places I know of.
