Includes case histories, new findings, and practical information on the treatment of migraines. The book discusses similarities among the visual hallucinations, or auras, that often precede a migraine and those that are induced by hallucinogenic drugs or deliria. Drawing on recent advances in chaos theory and neural simulation, he describes these "hallucinatory constants" and what they reveal about the working of the brain. Another addition to this edition details recent advances in the treatment of migraine, including the many new drugs developed over the last two decades, as well as alternative, non-drug approaches.
