I like most of Oliver Sacks's books. I think "The Man Who Mistook His Wife for a Hat" and "An Anthropologist on Mars" are major contributions to the understanding of the human mind. I do have a problem with "Migraine" however. My experience as a migraine sufferer and as a clinical psychologist has left me in no doubt that the fundamental causes of migraine headaches are physical, not psychological. I have no doubt that stress can make the attacks worse, but I believe most migraines are triggered by such physiological factors as allergies (particularly MSG, chocolates, red wines, and well-cured cheeses), or by overexposure to bright sunlight, too much sugar, or by overexertion or overstimulation with an accompanying lack of rest. Sacks takes a Freudian view of migraine, which I believe is inaccurate. I now get migraine attacks perhaps a tenth as often as a few years ago, and the improvement has not been due to psychotherapy or any earthshaking insights, but to my avoiding MSG and chocolate and to my doctor perscribing Imitrex. Imitrex is a miracle medication for patients who can tolerate it. (It can cause a dangerous increase in blood pressure in some people, hence the need for a doctor's prescription.) Sacks has written some fine books, but I don't think this one belongs near the top of the list.
