The real causes of migraine headaches has not yet been discovered, although there are a few theories why we have migraine headaches. The most common theory is that a change in the blood flow within the brain is one of the triggers that causes migraine headaches. Another theory about migraine headache is that it could possibly be caused by pain sensing chemicals called neuropeptides.
Many medical professionals think that neuropeptides relax the smooth muscle that surrounds the cranial blood vessels. This relaxation causes the blood vessels to dilate. This blood vessel relaxation increases the flow of blood and other cranial fluid to the brain. This increase in fluids is thought to be the cause of migraine headaches.
These cranial fluids cause swelling, pain, sensitivity, tissue and blood vessel inflammation during the time of migraine headaches. Some people think that the aura that is sometimes seen during a migraine headache is caused by the constriction of blood vessels that became dilated during the beginning phase of the migraine headache.
Another theory as to the reason for migraine headaches has been linked to genetics and inheritance. These theories state that a child of migraine sufferers will have a 50% chance of getting migraine headaches too.
The chances of inheriting migraine headaches become even greater if both parents are known to suffer from this painful type of headache. Should both parents be known to have frequent migraine headaches the chances of the child inheriting migraine headache symptoms rises to about 70%.
Even though some professionals are persuaded that inheritance plays a big part in migraine headaches, the genes that are thought to be the causes of migraine headaches have not been identified or even isolated yet. When we start to experience migraine headaches the only warning signs that we may expect to receive are a throbbing pain in the temple area and slight sickness.
As the symptoms of the migraine progresses, the pain becomes much more severe. Unfortunately, since the causes of migraine headaches have yet to be found and we don’t know what triggers these attacks, there are no medications to cure this type of headaches yet.
