Why does light stimulate to aggravate migraine headache
The scientist, through going on to the blind migraine headache patient in various degree than to finding after observation according to the Xinhua News Agency, a kind of retinal ganglion cell may conduct all information, aggravate the root of the trouble of migraine headache, therefore can explain why it is more troublesome why a migraine headache patient see all while having illness coming on.

A group of theses which researchers issued on the latest " neurology monograph of Nature Journal " of Israel's woman executive officer's medical centre of American shellfish silk are spoken, a kind of retinal ganglion cell of the new discovery may cause migraine headache to aggravate.

Agence France-Presse invokes the thesis content to say, this kind of ganglion cell is called opsin of sensitization on January 10, exist in the retina. Scientist choose two the intersection of migraine headache and patient go on than right, one to have the intersection of sensitization and blind person of ability at all, another group can be distinguished day and night, but there is no blind person that image caught ability.

First group of blind person's migraine headache patients keenly feel after stimulated by strong light and has not aggravated when having illness coming on; And the second group of patients is stimulated by strong light while having a headache, keenly feel and obviously strengthen, and is especially sensitive to blue light and gray light.

Scientist say, have the intersection of sensitization and blind person of ability at all with can distinguish day and night, have image catch blind person of ability, compare, the retinal function distinguishes it is the former's sensitization opsin function lose but the latter's sensitization opsin function is intact. Show than to the result, it is opsin of sensitization that conducts sensitization information to the brain, cause headache to aggravate.

The scientist still further regards experiment mouse as the research object to analyze, find opsin of sensitization conducts sensitization information behind the brain, stimulate a kind of active electric activity happen in the brain cell, and even if the light source disappears and stays darkly, such electric activity will take place for several ten minutes and even several hours continuously too.

After why not stimulate by the light again this discovery has been explained, the migraine headache patient will also exist to aggravate symptom continuously to have a headache.

Migraine headache one unidentified effecting a radical cure difficult diseasing cause of disease so far. The scientist says, find this kind of sensitization opsin has important medical value, because perhaps can prevent opsin of sensitization from transmitting sensitization information to the brain through the medicine, thus get the result of relieving migraine headache.
