The Migraine Aura – Tricks From The Brain

by admin

Migraine headaches typically come in two forms: With and without having auras. The headaches themselves can be equally painful – regardless of whether or not an aura is present.

Statistics indicate that only around 20% of migraine sufferers truly encounter these auras. Nonetheless, I’ve really observed that the prevalence of aura sort migraines is substantially less than that.

What Is A Migraine Aura?

The aura is a distortion in perception. Most usually a migraine aura is a visual alteration or other sensory phenomena occurring just just before the pain phase of a migraine headache starts. The aura also generally ends prior to the headache itself begins.

Symptoms linked with auras may possibly contain flashing lights, geometric patterns, or distorted vision.

Nevertheless, some folks might have non-visual auras involving hearing sounds (typically buzzing), olfactory auras involving smelling odors, or tactile auras that manifest like a physical touching sensation.

Characteristics Connected With Auras Consist of:

o Flashing lights

o Wavy or zigzagging lines

o Visual spots or other shapes

o Blind spots or partial loss of sight

o Blurry vision

o Olfactory hallucinations, or the smelling of aromas that aren’t actually there

o Tingling feeling or numbness around the face or extremities

o Difficulty speaking or forming words

o Confusion

o Vertigo (dizziness)

o Partial and temporary paralysis

o Hearing loss

o Decreased sensation to touch

o Hypersensitivity to feel and touch

Migraine auras usually lasts from 20 minutes to an hour; Nonetheless some sufferers have been identified to expertise aura symptoms lasting up to two days. Migraine aura symptoms can and do vary tremendously from one migraine sufferer to the next.

“Negative” and “Positive” Symptoms

The most generally reported aura consists of flashing lights or zigzagging lines, recognized as the so-referred to as “positive” symptoms.

Partial or total visual field loss or vision blackouts are known as “negative symptoms”.

A mixture of so-referred to as “negative symptoms” (such as vision loss) with the “positive symptoms” (like zigzagging lines) make up the generally distinctive functions of a migraine aura.

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

Cortical Spreading Depression (CSD)

Unique imaging and magnetic brainwave studies strongly suggest that Cortical Spreading Depression (CSD) forms the biological basis for the “negative symptoms” of a migraine aura.

From studying a specific kind of migraine – Familial Hemiplegic Migraine (FHM) – recent findings have shown two genes are responsible for causing this symptom. These genes – which control the ion flow of calcium, sodium and potassium to the nerve cells – are damaged in individuals inclined to this sort of migraine. It\’s believed this genetic mutation makes a person’s neurons susceptible to CSD.

In essence, the nerve cells (or neurons) don\’t get correctly “recharged” – resulting in diminished or depressed neural activity. Whatever the reason, this Decreased activity slows down regular body functioning. If the affected neuron complicated occurs to control the sight centers (visual cortex) then visual disturbances or losses may possibly occur.

Nevertheless, as these neurons begin to react to or recover from the CSD, they might grow to be hyper excitable, resulting in visual phenomena such as flashing lights and zig zag lines. (It is kind of like the neuron’s compensate by rebounding and going into overdrive!)

This hyper excitability then activates the key nerve complicated behind the eye (trigeminal nerve). This initiates migraine headaches by activating the extremely pain-sensitive “dura mater” – the membrane sheet wrapping about the brain.

Calcium Channel Blocker Drugs

Researchers speculated that blocking the ion channels flowing by means of the neuron cell membranes would aid lessen migraine pain. Some suggested using drugs to slow down and block these channels – for example “calcium channel blocker” medications.

Calcium channel blockers (such as verapamil) are widely used to treat heart illness and high blood pressure. They’re also now extensively used to avoid migraine headaches. Regrettably, their effectiveness in migraine prevention is minimal at very best.

A Far better Approach

There is yet another choice – a migraine cure. Cure the migraine and never be concerned around their linked auras or pain once more.

Recent reports indicate migraine headaches can indeed be completely abolished – as a number of elite medical clinics catering to ladies have testified. Under their treatment protocols, migraines are totally eliminated in 80% of their patients.

These successes are restricted to ladies only, as addressing a females’s hormones is the basis of the cure. Some clinics have published their treatment protocols and even created them obtainable to the public.
