HOw much neurology do you know right now?
If you have a working knowledge base, then the Comprehensive Board Review in Neurology by Mark K. Borsody (Jan 2, 2007) is a good book.
If you are completely starting from scratch then Step Up to Medicine by Agabegi 2nd edition was pretty good. I used it for IM review, but I recall a neurology section...good introductory level stuff.
Good luck.
