Definition

Aura is a transient disturbance in neurological function that may precede an attack of migraine headache. These disturbances usually last 20–30 minutes, but may persist for as long as 1 hour. The classical migraine aura that precede attacks in about 30% of migraine sufferers is visual, and characterized by an arc of brightly colored lights that flicker and change shapes. These visual disturbances often surround an area of dimmed or absent vision.
