Aura (from the Greek word for breeze) is the word used to describe a series of neurological symptoms that may begin before an epileptic seizure or a migraine headache. About 15% of people who have a migraine will have the kind with an aura. The symptoms may include visual problems such as "scotomas" (losing vision for a short time, seeing zig-zag lines or floating spots etc.), vertigo, a ringing noise in the ears (tinnitus) and problems speaking.
