A Few Common Migraine Symptoms
A migraine with aura is not what most sufferers of migraines experience. This is contrary to the beliefs of many among the general public, as most people seem to think the visual symptoms that accompany this type of migraine are pretty much the norm for everyone who has this illness. But not only is this type of manifestation just one kind of migraine variant, but there is even a lot of variation within the aura symptoms themselves. They are not always vision-related symptoms.
The visual symptoms of a migraine with aura are what most people think every migraine is; namely flashes of light, blind spots, and so on. But since a migraine is a triggering of the person’s nerves to become oversensitive, the aura symptoms can appear in different ways as well. The person can slur their speech or suffer a lack of concentration, or perhaps become very sensitive to sounds and light. These are all symptoms of the classic migraine, or one with the aura, just as much as the visual symptoms.
Another type of migraine is sometimes mistaken for one with the aura, which is the ocular or ophthalmic migraine. This has similar visual symptoms to the standard aura, involving blind spots in the vision, as well as zigzagging or brightly flickering light. This type of migraine, though, might occur without a headache at all, as the phenomena originates in the blood vessels of the retina rather than in the occipital cortex, the area of the brain that processes vision (where the aura originates). So there is some debate about whether this is a migraine with aura at all, yet many doctors argue that the otherwise unexplained disturbances in the retinal blood vessels must also surely originate in the occipital cortex.
In the end, it doesn’t matter that much where the aura symptoms come from. The fact is that whether a person experiences an ocular migraine without the headache or a migraine with aura that includes the headache, they will probably try doing the same things to prevent the migraine’s arrival, and if or when it does come, they’ll use the same treatment methods in both cases. The one thing the aura does is give the person who experiences it a little more advance warning of the approach of the headache. Yet this could be a very mixed blessing indeed.
