Snap! You know when a headache is coming because it feels very strange. You feel dizzy as you feel the sudden sting in your head that feels like you’ve been hit by something. Not only that, you also feel dizzy, and you can sometimes feel a sudden ring in your ear and other discomforting symptoms. These increasing uncomfortable symptoms are called a migraine aura. The next thing you know, it’s a very painful migraine headache.
Understanding a Migraine Aura
A migraine is really nothing new. It is a condition that most of us have probably encountered. A migraine is basically caused by the changes in the nervous system. The cause of these changes are not yet clearly determined by scientists. However, it is possible that several brain chemicals play a role in the cause of this condition.
Theory has it that the excitation of the trigeminal nerve in the brain caused by a wave of nerve cell activity causes the release of a variety of neurotransmitters. These neurotransmitters then cause the blood vessels to change their size so that they eventually release more neurotransmitters which cause the person to feel the pang of pain due to the inflammatory process happening in the brain.
Now, how do we distinguish a headache from migraine? Migraine attack usually includes nausea, throbbing headache, vomiting, lethargy, and sensitivity to light and sound as its symptoms. There are in fact four phases of migraine that people often experience. These phases are prodrome, aura, attack and postdrome which are often distinguished by the symptoms manifested in the person.
Some people who have a migraine often experience the warning signs in the second phase. This second phase of migraine is what we call a migraine aura. It is often associated with sensory, motor, verbal and most commonly visual disturbances. This stage usually happens before a headache is felt.
A migraine aura includes a wide spectrum of neurological symptoms, which usually targets the senses. In some people, the neurological changes happening in the cortex of the brain cause changes in sight, hearing, and speech.
What does it feel like?
It is like an electrical wave that moves across the visual cortex of the brain causing disturbances in sight, hearing, and other senses. People who experience a migraine aura often see dark spots or colored spots, sparkles and zigzag lines which aren’t really there. Numbness, weakness, dizziness or vertigo (a spinning sensation) can also be felt. Speech and hearing can also be disturbed and memory changes, anxiety, and confusion can also be experienced.
In most adults, the aura is manifested before the occurrence of a headache. However, in children, aura can be experienced the same time as a headache. It is also possible with this condition to feel only the symptoms, so it is possible to experience a migraine aura without a headache.
It is often hard to predict whether a migraine attack is going to occur. Most of the time, people regard the attack as a mere headache and that the discomfort the sufferers feel is due to the headache. However, if it should be categorized, the occurrence of migraine can be predicted through the pattern of the attack as described in the different phases of migraine. The symptoms of these phases differentiate the condition from a headache.
Migraine aura is accounted as a very common type of migraine. The occurrence of migraine is often predicted with the symptoms associated with this second phase. Aside from it being one of the types of migraine, there are also some types that are identified which are characterized by how it affects the sufferer.
It often appears in different ways. Some people may experience dizziness or nausea, clouding or disrupted vision, sensitivity to light, difficulty in hearing or speech and ringing of the ear. Apart from these symptoms that affect the senses, this condition (for the worst case) can also be associated with lethargy (lack of energy), memory loss, mental confusion, vertigo and even hallucinations. These symptoms are common but can be frightening to some sufferers of this condition.
As the migraine aura affects the cortex of the brain, a person usually loses normal visual function. This can be regarded as a migraine visual aura. During a visual aura, a person can experience disrupted vision such as seeing zigzag patterns, sparkles and may even experience partial loss of vision or scotoma.
Another type of migraine aura is the sensory aura which can usually happen at the same time as visual aura or after. This aura causes the sufferer difficulty in controlling their motor ability due to numbness of limbs up to the arms which can occur over 10 to 20 minutes of the attack.
The sensation can also travel to one side of the face and tongue which causes disrupted speech and is then referred to as the dysphasic aura.
A migraine aura in general is not really a life-threatening condition and is most often short-lived. Fortunately, however, it does not omit the fact that it is a disturbing condition. Now, is there a way to prevent migraine from occurring? Certainly yes!
Knowing the symptoms of migraine and its phases can definitely help you take some measures to prevent the headache from occurring or avoid prolonged pain caused by the condition. After the early manifestations or occurrences of migraine, you should be able to note the factors that seem to trigger your migraine. While identifying these triggering factors, it is advisable to have a migraine diary to help you track down the causes of your migraine.

Certain tests like eye examination, CT scan(2), and MRI scan can also be advised to know what could be causing the symptoms.

- Pain relievers- over-the-counter pain relievers such as ibuprofen and aspirin. By far, aspirin is the most effective medication in the prevention of migraine aura. But as much possible, do not be too dependent on these pain relievers as it may cause medication-overuse headaches when taken for too long.
- Triptans- these medications block the pathways of pain in the brain. However, this treatment may not be safe for everyone especially to those with people at risk of stroke and heart attack.
- Anti-nausea drugs- can help relieve migraine accompanied by nausea and vomiting
- Botox injection- this can prevent occurrence of migraine in adults
- Antidepressants- some of its side effects include sleepiness and weight gain, but it can help relieve migraines and lets the patient rest
