What is a migraine with aura?

About 25% of people that have migraine experience what we call an aura. An aura is a reversible neurologic symptom associated with a migraine. Most commonly this is a visual symptom. Some people report flashes of light, dark spots in their vision, wavy or zigzag lines. Other types of aura can include sensory aura, which can include numbness or tingling in part of the body, or even language symptoms like slurred speech or trouble getting words out. Auras usually develop slowly and last between five and sixty minutes and typically they occur before the headache starts.
