As migraine headaches involves more and more people, research workers across the world are grappling with hypotheses to aid explain the elementary responsible constituents. Now an estimated 30 million people in America are disabled by migraines. While migraines could happen at any age, surveys reveal that the disease usually affects individuals between the ages of 10 and 40. And more or less 75% of migraine sufferers today are adult females.

Migraine infliction is induced by inflamed blood vessels and nerves near the brain. Although significant research has been done, the exact cause of migraines is yet a mystery. Scientists think that the condition may result from a series of chemical reactions in the central nervous system due to alterations in the body or surroundings. Some studies as well express that people impaired with migraine disorders may have hereditary sensitivity to triggers from their parents or grandparents. Research likewise shows that individuals with a single parent possessing migraines have a 50% chance of getting migraines.

There are various hypotheses about the reasons for migraines. The blood flow theory proposes that blood vessels narrow or expand. A contraction of the blood vessels constricts blood flow, inducing vertigo or troubles with sight. Alternately, when blood vessels broaden they push the nerves adjacent and cause pain sensation. Even another hypothesis focuses on chemical substance changes in the head where it is suggested that a suspension in the messages directed from one cell to another to contract or expand blood vessels induce migraine. Lately, migraines have also been related to genes where surveys have shown that inheriting abnormal genes that control the functions of certain brain cells can lead to migraines.

Generally, migraines are classified into two types – Classic Migraine and Common Migraine. In classic migraine, the individual develops optical symptoms (also well-known as ‘aura’) about 10 to 30 minutes before an attack. In common migraine there is no aura, but there are different symptoms similar nausea and vomiting. Migraines also hit women during menstrual shifts, and are believed to be hormone-related.

There is as well a relation between migraine and so called epileptic seizure disorders. The relation is most apparent in migraine-triggered epilepsy. Migraines affect about 15% of the epileptic population.
