The experiences are also different between different people. There are these common symptoms like searing and throbbing pain, which is one-sided at times but not at other times, some migraine patients may also have ‘auras’ before it onsets. But others do not have these auras.
These headaches may also lead to sweating, vomiting, nausea, chills, light/sound/smell sensitivity and/or fevers.
According to research, over 300 million people across the world (that’s 6-7 percent men and 15-18 percent women) have migraine headaches. Around 20 million migraine attacks take place every day.
There have been endless numbers of studies for determining the causes behind migraines. However, it has not yet been possible to find a thorough explanation of why migraines occur in different people. Lot of times the theories have been found to be of conflicting nature. But lot of them claim the following causes behind migraine:
-Excess flow of blood in the brain. There are studies that show that such headaches don’t follow constriction and reduction in blood flow, but only an increase by almost 300 percent. But after the migraine attack occurs, the blood circulation seems normal or even falls slightly.
-Neurological disorder associated with function of nerve cell. It is believed that migraines occur because of a neurological disorder associated with nerve cell activity which spreads across the brain, and thus causes pain.
-Vascular constriction within the brain. It is believed that migraines may also occur due to initial constriction in blood vessel and reduction in blood flow, and then the blood vessels dilate and stretch. This causes activation of neurons that signify pain.
-Alterations in serotonin (a brain chemical). It is believed hat migraine pain may be caused by inflamed and swollen blood vessels within our brain, when the levels fall.
As per recent study, it is found that folic acid and vitamins B6 and B12, supplements can help in reducing migraines by two times over 6 months. Even an earlier research has helped make same discovery. A studyconducted in 2004 and published in the European Journal of Neurology showed that it was possible to avoid migraine attacks by consuming high vitamin B2 (riboflavin) doses.
It has also been found that certain gene dysfunctions and mutations could increase the production of homocysteine. They could increase the risk of migraine attacks. The study found that homocysteine levels are reduced by vitamin B6 and B12. Researchers also discovered that a person could require lower or higher dosage for effectiveness, based on the person’s genotype.
Professor Lyn Griffiths claims that when all patients are given same dose of vitamins for same duration, it is expected that the subjects with TT genotypes (with decreased enzymatic rate) metabolize lesser homocysteine during the period of treatment against C allele carriers. This results in smaller decrease in homocysteine and resultant symptoms of migraine.
It is likely that TT genotypes, even though they have enhanced risk of disease, need higher dose of vitamins for showing the same effects as C alleles. Additional clinical trials are required for larger number of patients for testing this hypothesis.
She also says that their goal is to find the optimal dose of vitamin Bs depending on the patient’s genetic profile. According to her, the trial’s success has demonstrated that affordable and safe vitamin supplements could help in treating migraine patients.
Symptoms of migraine may still be caused due to other, more common, kind of vitamin deficiency.
According to an observational study conducted at the 50th Annual Meeting of the American Headache Society, it was discovered that 42% of patients suffering from chronic migraine had deficiency of vitamin D. The researchers also discovered that those suffering from chronic migraines for longer durations had more chances of being deficient in vitamin D.
All this indicates that all these new discoveries could be linked to different health consequences due to vitamin D.
