Why do migraines occur?

A migraine is one form of a headache that is commonly severe and debilitating. Migraine, which comes from the Greek words hemi or half and kranion or skull, is typically characterized by pounding headache and nausea. This condition occurs more frequently among women than among men. People who experience migraine commonly complain of a unilateral pain that lasts for as long as three long days and can be accompanied by nausea, vomiting, increased sensitivity to light and sound and can be aggravated by daily routinary activities. Migraines can be classified according seven subclasses and its signs and symptoms are phased. The four phases of the signs and symptoms associated with migraine are the prodrome, the aura, the pain or headache phase and the postdrome. When such phases are thought to be experienced, then one can be diagnosed to be experiencing a migraine attack.

There are several factors that contribute migraines to occur. Although the main cause remains to be in mystery, there were factors identified that help trigger its onset. Stress, hunger, and fatigue are the most commonly associated reasons why migraines occur. Along with that, it has been discovered that hormones play a great role in triggering migraine attacks. Hormones found in the brain that are known to have a specific function in initiating neurological activities such as cortisol and serotonin, are guilty of triggering the onset of migraines. Hyperactive transmission of cortisol followed by a sudden stop can cause irritation to some nerves that is then manifested by severe pain in migraine. Low serotonin levels permit vessels to constrict and dilate thereby, triggering migraines to occur.

The above mention causes are just few of the many and must therefore be addressed to be duly recognized and treated to prevent further damage to the condition.
