Sensitive nerve Too Could Be Major Cause Migraines

Until now, experts still agree if the main trigger of migraine is widening the artery outside the skull. But a group of researchers from Denmark to make sure that's not the cause because they found that the nerve fibers around blood vessels become very sensitive when dealing with the migraine attack.

The researchers came to the conclusion after seeing the results of MRI scans on 19 women who suffer from migraines and observe the condition of their arteries or blood vessels during an attack.

All the participants reported healthier and suffer from migraine without aura (migraine that is accompanied by symptoms of visual disturbances such as flashing lights or tingling in the hands and face).

This means that participants experienced migraine headaches was limited to one side of the head making it easier for others who are not the head of migraine to be scanned so that researchers can tell the difference when both conditions occur migraine attacks.

The result, researchers found that the arteries outside the skull was not dilated during a migraine attack. If anything, the researchers found only slight widening in the side of the head migraine, while the other head did not feel any pain.

Not only that, this finding also raises another question related to how the drugs are often prescribed to deal with migraines such as sumatriptan. Because the researchers found that the blood vessels in the skull is still wide despite the migraine was gone.

It means that the medicines do not work as long as this is understood a lot of people. This condition is found to researchers after participants were given certain migraine medications before undergoing another MRI scan.

In other words, the findings of a team of Danish researchers has raised a new theory that migraine pain is caused by nerve fibers around blood vessels become extra sensitive head, instead of widening the artery outside the skull.

"Our findings are very important to provide a deep understanding of migraine, including migraine underlies another study in the future," said one researcher Faisal Mohammad Amin, a PhD student from the Danish Headache Centre, Glostrup Hospital, Denmark.

"At the same time, these findings can also be used to provide guarantees on the artery migraine sufferers who fear they will 'explode' during the attack. Fact they did not experience it," he said as reported by the Daily Mail, Thursday (18/04/2013) .
