Informational book, though somewhat outdated (I read the fourth edition). A lot of the information is still relevant, but there has definitely been some changes in the treatment of migraine since the early 2000s. The book is a quick read and great starting place in understanding migraine and treatment. Would definitely recommend and would love to see it updated in the future.
I read the 1998 second revised edition, having 98 pages. This short volume contains a wealth of information. Though most of the information presented isn't new to me, I would highly recommend this to those seeking answers and insights.
