[Middle English, gentle breeze, from Latin, from Greek aurā, breath.]
From the Greek meaning ‘breath’, the word aura is mostly used in the metaphorical sense of someone having simply ‘an aura’ about him or, more vividly, one of ‘wisdom’, ‘saintliness’, or ‘evil’. However, for those suffering migraine or epilepsy, an aura is no longer simply a metaphor relating to their perception of a person in the external world but now a disagreeable perceptual experience heralding an impending attack of their sick headache or convulsion (grand mal). In the case of migraine the aura is most commonly visual. The images do not relate to previous visual experience but can take the form of scintillating, wavy patterns of bright, silvery light that superimpose on the current visual image — but in contrast to the latter they persist when the eyes are closed.
In epilepsy the simplest form of aura may be an ill-defined feeling of uncertainty or nausea preceding a convulsion. This may be an expression of changes in the cardiovascular and digestive systems induced by the autonomic nervous system as an early aspect of the epileptiform activity within the brain. Undoubtedly the most remarkable ‘aura’ occurs in the particular type known as ‘temporal lobe epilepsy’. At its simplest the aura may take the form of a familiar odour, or more commonly a disagreeable or even disgusting one. At its most complex the aura can be a perceptually complete image of a person with no counterpart in the external world. Such an image is to be distinguished from one summoned voluntarily in the mind's eye, or from an illusion due to the brain's interpretation of conflicting visual stimuli from the external world. Instead, that of the aura is a remarkable product of the uncontrollable discharge of neurones associated with an epileptiform focus in the temporal lobe(s) of the brain, demonstrable in the recording of the electrical activity of the brain, and, when the severity of the condition demands, abolished by surgical removal of the offending lobe.

A peculiar sensation preceding the appearance of more definite symptoms. It is a well-known phenomenon in humans and, on good clinical grounds, assumed to occur in animals, appearing as behavioral abnormalities.

An aura is a perceptual disturbance experienced by some migraine sufferers before a migraine headache, and the telltale sensation experienced by some people with epilepsy before a seizure. It often manifests as the perception of a strange light, an unpleasant smell or confusing thoughts or experiences. Some people experience aura without a subsequent migraine or seizure (see silent migraine).
When occurring, auras allow epileptics time to prevent injury to themselves and/or others. The time between the appearance of the aura and the migraine lasts from a few seconds up to an hour. The aura can stay with a migraine sufferer for the duration of the migraine, depending on the type of aura this can leave the person disoriented and confused. It is not uncommon for migraine sufferers to experience more than one type of aura during the migraine. Most people who have auras have the same type of aura every time.
Auras can also be confused with sudden onset of panic, panic attacks or anxiety attacks creating difficulties in diagnosis. The differential diagnosis of patients who experience symptoms of paresthesias, derealization, dizziness, chest pain, tremors, and palpitations can be quite challenging.[1]

An aura sensation can include some or a combination of the following:
The specific type of sensation associated with an aura can potentially be used in an attempt to localize the focus of a seizure.
Auras share similar symptoms with strokes, but onset is more gradual with auras.[3] Auras can last from several seconds to as long as an hour, and can sometimes end with feelings of extreme tiredness, weakness, heart palpitation, sweating and warmth throughout one's body.
The onset of an aura can provide an early warning for those experiencing migraines.
