Yes I think it's definitely worth it. Neuroanatomy is a tricky subject, it would not be easy to understand it just by reading a book. I believe videos are a must for this. You can watch kaplan videos. If you have a lot of time you can also try dr. Najeeb's videos for a few main/difficult chapters only e.g. the tracts. He explains everything very well but obviously his videos aren't Usmle oriented. So in my opinion watch them for only the chaps you're having a hard time understanding. For the rest, there's always kaplan videos. This is what I did and it helped me.
I am studying neuroanat nowadays.
I started with high yield neuro anat. it took me 3 days to finish that book. its a difficult book to do. and some of the concepts were not clear in it.
I watched the kaplan new videos in 2 days and it really helped me. sorted out all my concepts. i am doing rx and qbank now and am getting almost all the questions right now. I hope this helps
