Many people will give different reasons for having any form of headache starting from family issues to the matters of the diet like indigestion or so.
However, have you ever experienced migraine type of a throbbing headache? This can really make your brains thick for a moment, before you find yourself.
So what is this migraine?
The brilliant intelligence of our doctors defines it like this:
Migraine is a neurological syndrome involving changed physical experiences, throbbing headaches and nausea. A typical migraine headache is one sided and will last for about four to seventy two hours.
Other accompaniments
People who have experience migraines often complain of vomiting, increased bright lights sensitivity –photophobia and also noise-hyperacusis.
What precedes migraines?
Suffers of migraines can first experience and aura before they are confronted by the actual headache.
What is an aura?
An aura is the sensitive annoyance experienced by some migraines sufferers prior to a migraine headache, which kind of resemble that sensation an epileptic person endures before a seizure.
More often than not, this will materialize as strange sensitivity to bright light or smell.
The time between the manifestation of the aura and the onset of a migraine or seizure can be somewhere from a few seconds up to an hour.
Most people who have auras have the same type of aura every time. But, if you experience one, this does not necessitate a migraine.
Examples of these aura sensations
Visual Changes such as bright lights, zigzag lines and alteration in the size or shape of objects.
Scotoma is an area of loss or impairment of visual acuity (is acuteness or clearness of vision, especially form vision, which is dependent on the sharpness of the retinal focus within the eye and the sensitivity of the interpretative faculty of the brain) surrounded by a field of normal or relatively well-preserved vision.
Examples include; Blind or dark spots in the field of vision, curtain-like effect over one eye and gradually spreading spots.
Scintillating scotoma usually begins as a spot of flickering light in the center of the visual fields, which to some level obstacles the field of vision.
The scotoma then expands into one or more shimmering arcs of white or colored flashing lights.
An arc of light may gradually enlarge, become clearer, and may take the form of a definite zigzag pattern, at times called a fortification spectrum.
It may be bilateral or unilateral. Also may comprise of sparkling, pulsating patches that are often curved and tunnel vision (is the loss of peripheral visions(s a part of visions that occurs outside the very center of gaze) with retention of central vision, resulting in a constricted circular tunnel-like field of visions (is the angular extent of the observable world that is spotted at any given moment).
What causes migraines?
While the accurate cause of migraine remains unknown, the most extensive theory is that it is a disorder of the serotonergic- means related to the chemicals that are used to relay, amplify and modulate signals between a neuron (responsive cells in the nervous system that process and transmit information by chemical signals within the neuron) and another cell- neurotransmitter.
It is also deemed that there are migraine variants that originate in the brainstem and involve dysfunction in calcium and potassium ion transport between cell membranes.
