I think the easiest way to find out is to go to freida by logging on to www.ama-assn.org and search for freida. Then click on freidaonline, then residency/fellowshipTraining program search.
Then search for all neurology programs.
There is a list of 119 neuro programs by state.
Click on each program . This will give you the details of each program. Scroll down and go to 'Educational benefits'. This has info about PhD training, MPH/MBA training and many other features.
This is more convenient than opening websites of all programs.
okay. i checked the educational benefits, as you suggested. many programs do not have that info available... and, of the ones that do, i could only find 3 (yale, cornell, and mayo) that answer yes to phd training. if the info wasn't available, i went to the program's webpage. that didn't seem to help, either.
programs like einstein have "Medical Science Pathway" for some internal med subspec, but unfortunately not for neuro.
wash u has the "Physician-Scientist Training Pathway", but that is designed more for MSTP students.
i'm up for any other suggestions you might have.
