Neurology has become a much more competitive field this year, but this trend is also seen across all the specialties. I think this is due to multiple reasons, primarily being due to more applicants overall as schools increase class sizes and more FMGs are competing as well. Also, what seems to be the trend is more and more people going into specialties as opposed to primary care due to lower compensation, DNP's etc... Just looking at our schools match list this year, I see 4 that matched into neurology up from only 1 each the last 2 years!
I personally heard from a few applicants on the neuro interview trail who were primarily interested in doing interventional stuff and had applied to a few specialties that could lead them down this path (neurosurg, vascular surg??). Also now with neuro icu's being put into hospitals, those who loved neuro but skipped it due to its previous lack of intensive care, are choosing neuro. All this is my opinion and what I have observed over the interview trail, so make of it what you want.
I, myself did not match this year and was lucky enough to scramble into a DO neuro spot even though I was an average applicant.
