Abstract
The typical aura associated with migraine is characterized by visual or sensory and speech symptoms, with a mix of positive and negative features and complete reversibility within 1 hour. However, auras are not an exclusive migraine-dependent phenomenon. There have been descriptions of aura occurring in association with cluster headache, hemicrania continua, and even with chronic paroxysmal hemicrania. In addition, the occurrence of aura without headache or followed by a headache resembling the criteria of tension-type headache is encountered in clinical practice. This paper reviews the literature about auras in non-migraine headaches and the features involving this uncommon presentation. The possibility of a specific genetic origin for the auras, not related to the primary headache type, also is raised.
