migraine usually in two forms: with and without aura. The headaches can be equally painful, whether there is an aura.

Statistics show that only about 20% of migraine sufferers actually experience these auras. But I have actually found that the prevalence of migraine aura give much less than that.

What is a migraine aura?

The aura is a distortion in perception. Most often a migraine aura is a visual change, or other sensory phenomena just before the pain phase of migraine begins. The aura also typically ends before the headache itself begins.

Symptoms associated with auras may flashing lights, geometric patterns, or distorted vision.

However, some people of non-visual auras with hearing sounds (usually buzzing), olfactory aura with smelling odors, or tactile auras that manifest like a physical sensation of touch.

Characteristics are associated with Auras:

Flashing lights

Wavy or zig-zag lines

Visual spots or other forms

Blind spots or partial loss of vision

Blurred vision

Olfactory hallucinations, or the smell of flavors that are not really there

Tingling or numbness of the face or limbs

Difficulty speaking or forming words

Confusion

Vertigo (dizziness)

Partial and temporary paralysis

Hearing loss

Reduced sensation to touch

Hypersensitivity to feel and touch

Migraine aura usually lasts between 20 minutes to an hour, but some stakeholders are known to experience aura symptoms lasting up to two days. Migraine symptoms can vary greatly and must be of a migraine patient to the next.

“Negative” and “positive” symptoms

The most commonly reported aura consists of flashing lights known or zigzag lines, like the so-called “positive” symptoms.

Partial or complete vision loss or vision blackouts are called “negative symptoms”.

A combination of so-called “negative symptoms” (such as loss of vision) with the “positive symptoms” (like zigzagging lines) are the typical features of a migraine aura.

Vision blackouts – the “negative symptoms” – are caused by a depression of nerve activity. On the other hand, the zig-zag lines by the hyperactivity of the nerve cells are created.

Cortical spreading depression (CSD)

Special imaging and magnetic studies strongly suggest brainstorm that cortical spreading depression (CSD), the biological basis for the “negative symptoms” of a migraine aura is.

From the study of a particular type of migraine – Familial hemiplegic migraine (FHM) – Recent evidence has revealed two genes responsible for causing this symptom. These genes – the ion flow of calcium, sodium and potassium, guide the nerve cells – are people willing to damage this type of migraine. It is believed that this genetic mutation makes a person more susceptible to CSD neurons.

In the nucleus of nerve cells (neurons or) not right in “charged” Follow diminished or depressed neural activity. Whatever the reason, slowing down the reduced activity of the normal body functions. If the affected neuron complex happens to the eye centers (visual cortex), then visual disturbances or losses arise control.

However, as these neurons respond to or begin to recover from the CSD, they can be hyper excited, which in the visual phenomena such as flashing lights and zig-zag lines. (It’s kind of like the neuron recovered through and goes into overdrive compensation!)

This hyper excitability then activates the major nerve complex behind the eye (trigeminal nerve). This triggers migraine by activating the very pain-sensitive “dura mater – the membrane sheet wrapping around the brain.

Calcium channel blocker drugs

Researchers speculated that blocking the ion channels would flow through the neuron cell membranes contribute to migraine pain. Some suggested the use of drugs to slow down and block these channels, for example, “calcium channel blocker drugs.

Calcium channel blockers (eg verapamil) are widely used to treat heart disease and hypertension. They are also now extensively used to prevent migraine. Unfortunately, their efficacy in migraine prevention is minimal at best.

A better method

There is another option to cure a migraine. Cure the migraine and never again associated auras or pain of their worries.

Recent reports indicate migraine may in fact have abolished entirely as a number of elite clinics catering to women testified. After their treatment protocols, migraines are completely eliminated in 80% of their patients.

These successes are limited to women, such as addressing a women’s hormones is the basis of healing. Some clinics have published its treatment protocols and even made them available to the public.

The Women’s Health Institute of Texas believes that a migraine cure certainly eliminates the migraine auras at all – and concern over the need resulting migraine may not, at least in women.
