This is a thick, well researched bookshelf manual, especially helpful for the medical literature reviews of various migraine types.

The author's perspective is a bit old-school, though up to date. He's interested only in medical documentation (and not alternative medicine). His chapter intros are stories of a patient's interaction with an MD, and those stories are a bit forced. But it's a good reference, especially good at the literature reviews for the various flavors of migraine.

The Kindle version is poorly formatted with bad chapter and section markers that are easy to miss.
