It seems from this book that a crucial aspect of migraine is the holding-back of something emotionally. There is so much information from Dr. Sacks (yes, a bit dry at times, but at most other times readable and even entertaining) that you can read this book in a nonlinear fashion, picking it up and putting it down, skimming until you find what's useful to your specific situation. Dr. Sacks found in two years of his study that over half the people he examined stopped having migraines! Why? Because he was taking an avid interest in them several times a month, and the migraine was no longer necessary as an embodiment of something the patients weren't dealing with emotionally.
Obviously there are many more causes of migraine, but for me that was immensely helpful and, over time and with better communication, I now only get them a couple of times a year, knowing that I can turn to this book to find out virtually anything I need to know. When I had my first optical migraine, I didn't panic because I'd seen the drawings in this book of the schomata (sp?) and knew what it was.
If you have migraines and can read, do yourself a favor and get a copy of this book. I don't care if you find it new or used. Just get it, and start skimming. You will find yourself in its pages and can perhaps start on the road to healing.
This is a widely misdiagnosed and incorrectly treated malady and sufferers need to be INFORMED about what is happening to them and why it is happening. Save yourself lots of grief and pain, read this book and you will be well armed in your fight for relief from this horrible malady.
I'm updating this review due to some of the unbelievably idiotic negative reviews some have given this book, one who admits they haven't even read it! After reading this book several years ago and most anything else published on migraine since, I can still say this is the book that is an absolute "Must Read" for any migraineur. You can't properly seek treatment until you understand what migraine actually is, not a 'headache' but a neurological disease, and this book will arm you with the most important weapon there is - correct information!
