aura (aw´rә) pl. auras, au´rae  a peculiar sensation preceding the appearance of more definite symptoms. An epileptic aura precedes an epileptic seizure and may involve visual disturbances, dizziness, numbness, or any of a number of sensations which the patient may find difficult to describe exactly. In epilepsy the aura serves a useful purpose in that it warns of an impending attack and gives the patient time to seek privacy and a safe place to lie down before the seizure actually begins.A migraine aura precedes about 15 per cent of migraine headaches, warning the patient that an attack is imminent. When it occurs the patient should rest in a quiet, darkened room.
