Migraine aura affect approximately 15% of people who suffer from migraines in the world. This is of particular types of migraines that are heralded by odd visual and tactile stimuli that signal the onset of migraine. Know the symptoms of a migraine aura, you can get information before they are full of shots, in one way while aura migraines are heavier than regular migraines, they at least have the advantage of warning signs that you can get drugsquickly.
One of the symptoms of a migraine aura has given birth to her name. This symptom is visual in nature, usually as black spots danced before the eyes of a person or a blur at the edges of the odd field of a person of vision, a little 'blurry like looking through a fish-eye lens. Other people experience bursts of color or "stars" in their vision and dizziness sudden, similar to what happens with most people, if they are sometimes too fast.

A tactile level, andThe signs of a severe headache coming on, migraine aura and sometimes numbness in the face or fingers, and / or a general feeling of "tinglyness," such as tingling, the whole body.
The reasons for the eye is blurred, because they affect migraine aura, to some extent, the nervous system of the sufferer. In a person with migraine, the outer surface of the brain starts to overload stimuli of pain that causes blockage of the transmitted and receivedImpulses from the body. The brain constantly sends and receives electrical impulses through the nervous system, and the pain of a migraine interferes with these signals.
The optic nerves, with the closest distance to the brain, are the first to be affected by this overload. This manifests itself in symptoms of visual migraine aura. The pain is basically to send feedback to the eyes with messess signals to the brain. On a more serious level, exceptDance spots and blurring, serious migraine aura are known by the way, input from the eyes, so black-out and temporary loss of vision in migraine.
The numbness and tingling is also connected to this symptom. This is serious, as can a severe migraine aura not only of numbness in the victim, can actually cause a temporary loss of motor coordination and control functions. The impulses of the brain that accompany a migraine can literally cut theman's ability to move his limbs.
The original theory behind the aura of migraine was that the blood vessels that carry blood to the brain, the pain is caused by the contract and migraine symptoms were brought on by loss of blood supply to the brain and increased pressure blood trapped within the skull and paranasal sinuses. The main support base for this theory comes from the fact that the sympotoms of a migraine aura experienced by planes similarPilots during blackout, when a severe gravitational forces forced into a curve of blood from the brain. We now know this theory is wrong.
A study of migraine with aura EEG shows a depression, or a decrease of brain activity and electrical impulses on the surface actually affected, which makes the headache. Unfortunately, this area "depressed" on the surface of the brain surrounded by an aura, or crown, the nerve cells hyperstimulated. And 'this area hyperstimulatedactually cuts each input and output of this part of the brain during a migraine aura.
At worst, it is known to have migraine aura is not only the loss of motor function and vision, but to cause unconsciousness in the victims. The lack of impulses from the brain to certain parts of the body, connected with stimulus oveload pain in the affected part of the brain, causing a temporary loss of consciousness.
The doctors and neurologists have studied the modelMigraine, particularly migraine aura, for several years. While to date there are many theories about the cause of it, there is still no definitive conclusions. Painkillers and drugs were, however, reducing the impact of migraine aura and let the victim get to relieve, if they come to feel that develops.
