ABSTRACT
In Chapter 1, we recalled that Hippocrates, Arateus, and other physicians of the ancient World had noted an association between a particular form of headache and visual disturbances. Pelops had referred to neurological symptoms that sometimes precede epileptic attacks as ‘‘aura’’ and, much later, this term was used to refer to similar symptoms that could occur in migraine. Visual symptoms are certainly the most common type of migraine aura, and it can take many forms. Although Le Pois described a case of sensorimotor aura as early as 1618, it was Liveing’s work in the nineteenth century that first emphasized the broader range of auras that might be encountered.
