For many years now, neurologists would actually relate the occurrence of migraine to the vasodilatation of the nerve cells that surround the brain, which then causes the inflammation and pain of the head. These vasodilatation or enlargement of the nerve cells then triggers the release of chemicals which then causes changes the circulation of the blood in the brain. However, recent studies have shown a different set of migraine causes. Researchers now propagate the theory that the chemical changes do not really occur and affect the blood vessels, but that the brain is the one being affected by these chemical changes. Other than that, studies have also shown that migraine can be a hereditary condition and can happen to almost anybody especially when there are triggers that increase the possibility of a person to have a migraine attack.

Some of the most common migraine causes would include, stress, sleeping difficulties, lack of food, bright or flashing lights, strong odors, smoke from cigarettes, alcohol, chocolate, caffeine, extreme temperatures, excessive exposure to sunlight, food chemicals, among all else. It has also been shown that women are more prone to having migraine, and researchers now say that this is because of hormonal changes that happen in their bodies, usually around the time they have their menstruation. The so-called menstrual migraine usually occurs two days prior their period or for some, a day after it. Theories have shown the correlation between changes in the estrogen level and migraine headaches. Migraine causes vary for each individual depending on the triggers that preempt these attacks.
