Clinical neurophysiology of migraine with aura. People who have migraine with aura are at a mildly increased risk of stroke. Migraines are also more common in women than in men.

Many of the same factors that trigger migraine can also trigger migraine with aura, including stress, bright lights, some foods and medications, too much or too little sleep, and menstruation. The electrical and chemical waves can occur with normal functioning of the nerves and do not cause harm to the brain. The most common type of aura is visual aura, which occurs when a wave of electrical activity spreads through the visual cortex and causes visual symptoms. This electrical or chemical wave can occur in areas that process sensory signals, speech centers or centers that control movement. The part of the brain where the electrical or chemical wave spreads determines the type of symptoms you might experience. There is evidence that the migraine aura is due to an electrical or chemical wave that moves across the brain. Your doctor will need to rule out more-serious conditions, such as a stroke.
