A migraine results in a pulsating sensation or a severe throbbing pain, usually on single side of the head. The headache due to migraine is often associated with symptoms of vomiting, nausea and extreme sensitivity to sound and light. Migraine can result in significant attacks of severe pain for hours to days and the severity of the pain is so much that it is disabling. Warning symptoms referred to as aura may occur with or before the headache. These symptoms may include blind spots, flashes of light or tingling in your leg, arm or one side of the face. What causes migraine?
What Causes Migraines?
The cause of migraine is unclear. According to a popular theory, the blood vessels in the brain go into spasm or become narrower, which causes the symptoms of the aura. Soon afterwards, the blood vessels dilate, which causes the headache.
However, this theory does not explain the whole story and may not be the main reason behind the migraine attack. Now it is thought that the activity of certain chemicals in the brain is increased and confusion signals are sent out from parts of the brain, which results in symptoms. What exact change occurs in brain chemicals is not known. It is also unclear why these changes develop in people suffering from migraine.
Trigger Factors of Migraine
Though it's not clear to know what causes migraines, many possible triggers of migraine have been suggested such as hormonal, physical, emotional, dietary, medicinal and environmental factors.
Some females have migraine attacks at the time of their menses, possibly due to changes in hormonal levels such as estrogen levels during this time. These types of headaches usually happen between 2 days before your periods begin and 3 days after your periods end. Some females experience migraine headaches only during this time, their headache is referred to as pure menstrual migraine. However, majority of the females also have them at other times.
In many females migraine headaches may improve post menopause, although, in some females, migraines may be triggered or made worse by menopause.
