If you suffer from migraines, you probably have already heard the term migraine aura. Simply put, An aura is simply the different neurological symptoms that may happen before and during a migraine headache.

According to some specialists, migraines with an aura is usually seen in about 20% to 30% of people with migraines, which means it can be experienced by every 1 out of 5 people.

Migraine auras have been studied by different specialists. Some time ago, they believed that aura was caused by the brain blood vessels constricting. However, their opinions have been changing lately and the new cause that is now being pointed out is the hyper-excitability of the brain cells. This is due to the brain’s own chemistry but that has an effect on the normal perception and senses.

An aura can last between 5 minutes and 2 hours and is completely reversible. Despite some cases where an aura lasts days, weeks or even months, this is a very rare situation.

Those with migraines report their auras are different from person to person. While some say that the headache precedes the aura, for others the headache and aura coincide. There is even a third group of people that state that sometimes they only experience the aura but they have no headache afterward.
