How to identify Migraine Aura
Migraine can occur with or without an aura. An aura is a visual imagery which ovvurs by the altering of the signals to the brain. It serves as a warning sign to people suffering from migraine so that they can be better prepared to handle the migraine attack. If you are driving or at work, quickly stop what you are doing and find a quiet place to relax and be prepared to face the attack to follow.
The aura could be visual or could be in the form of dizziness, nausea, vomiting, tiredness etc. A visual aura resembles a chemical or electrical wave that moves across the brain's visual cortex. Visual cortex is that part of the brain that processes visual signals.
Migraine auras normally lasts from 20 minutes to an hour; however some sufferers have been known to experience aura symptoms lasting up to two days. Different people have different types of auras and experiences. Some people suffering from occular or visual migraine can even experience temporary loss of vision. Hence it is very important to be prepared especially when you are in the middle of something critical like driving etc.
Migraine usually comes with a trigger. A trigger is one that causes the onset of a migraine headache. It could be lack of sleep, stress, a particular diet or food etc. It is important to identify your trigger so that you can stay away from it in future.
Most migraine aura lasts for about an hour. In sensory or motor aura feelings of heaviness can persist for several days, even a week or two in some cases. Migraine headache can be treated by natural means. It is important to treat migraine at its roots by prevention from occuring instead of treating it when it does occur.
