An aura is a neurologic symptom that is associated with a migraine headache either immediately preceding or during a migraine attack. It can last from 5-60 minutes. The most common aura is visual -- seeing flashing lights, zigzag lines or losing part of your vision. However, auras can also be sensory, such as a pins/needles feeling in the hand or face; motor, with weakness of a hand or arm; or involve speech, such as confusing or slurring words.
Auras may also be experienced as numbness and tingling in the face, arms, or legs. Some migraine sufferers experience weakness, slurred speech, or even brief paralysis.
The aura of migraine headache is a neurologic dysfunction and can encompass or embody any part of the Central Nervous System. You can have a disorder of thinking, vision, hearing, speaking, as well as disorder of smelling. During the migraine headache there can be photophobia (light sensitivity), phonophobia (sound sensitivity), and osmophobia (smelling bad things or having a disorder of smell). This needs to have preventative treatment and not be treated with acute medications.
Some people get an early warning signal that a migraine is headed their way. Their migraines are preceded by an aura. The auras can be colored or white lights that flicker at the edge of sight, hallucinations, dark or blind spots at the edge of vision, or tingling or numbness-generally in the face or hands. Aura symptoms can start as little as a few minutes, or as long a few days, before the migraine pain is felt.
With some people, there is no aura, but they can experience euphoria or other mild symptoms before the migraine pain begins.
