Not all auras are followed by headaches, but since they typically precede the headache phase, they can serve as another warning of a potential headache.
The headache phase of a migraine attack is characterized by pain on one or both sides of the head. This phase typically lasts from several hours to up to three days. Headache phase pain can vary from person to person and from incident to incident, with some migraine attacks causing mild pain, while others are debilitating.
Besides pain, headache phase symptoms can include nausea, inability to sleep, anxiety, and sensitivity to sound, light and smell. Even everyday activities — like turning on the lights or participating in physical activity — can aggravate people with migraines during this phase. For those that do, postdrome may not follow every migraine attack they experience, and the length of this phase can vary. Postdrome can be just as debilitating as headache, according to some people with migraine.
Symptoms of postdrome include fatigue, body aches, trouble concentrating, dizziness and sensitivity to light. Migraine aura symptoms include temporary visual or other disturbances that usually strike before other migraine symptoms — such as intense head pain, nausea, and sensitivity to light and sound.
Migraine aura usually occurs within an hour before head pain begins and generally lasts less than 60 minutes. Sometimes migraine aura occurs without headache, especially in people age 50 and older. Most people who have migraine with aura develop temporary visual signs and symptoms, which tend to start in the center of the field of vision and spread outward.
These might include:. See your doctor immediately if you have new signs and symptoms of migraine with aura, such as temporary vision loss, speech or language difficulty, and muscle weakness on one side of your body. Your doctor will need to rule out more-serious conditions, such as a stroke. There is evidence that the migraine aura is due to an electrical or chemical wave that moves across the brain. The part of the brain where the electrical or chemical wave spreads determines the type of symptoms you might experience.
This electrical or chemical wave can occur in areas that process sensory signals, speech centers or centers that control movement. 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. The electrical and chemical waves can occur with normal functioning of the nerves and do not cause harm to the brain.
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.
