One of the most common symptoms of a migraine is an acute throbbing pain which is normally located on just one side of the head near to the area of the temple. Migraine headaches are also frequently accompanied by other symptoms which include sensitivity to noise and light, queasiness and sometimes vomiting.
Migraine headaches are relatively common and affect about one in ten people in America, or more than 28 million Americans. They are also much more commonly experienced by women rather than men (about 3 times more women suffer from migraine) and can also be sse sometimes in children.
Although migraines are so common and often very painful with attacks lasting anywhere from a few hours to two or three days, only roughly half of all sufferers consult their physician and the remainder choose to suffer in silence.
Migraine headaches had long been thought to be were caused by a of dilation of the blood vessels in the head but, even though there is no general consensus, medical opinion seems to be moving away from this theory in favor of a genetic cause for this condition. It is now believed that migraines results from the interaction of brain chemicals such as serotonin with the nerve cells. At present however the truth of the matter is that we are really not sure what cause migraines.
In fact there are two types of migraine, the first of which is known as ‘classical migraine’, which is characterized by an associated ‘aura’. Here the term ‘aura’ is used to refer to visual light effects that are experienced just prior to the arrival of a headache including such things as flashing lights and bright light spots. In some people a total loss of vision can be experienced for some minutes before the onset of the headache.
The second form of the condition is simply a migraine without the ‘aura’.
Just as we do not know what causes a migraine, we also have very little idea about exactly what triggers an attack, although there are a number of factors that do seem likely to trigger an attack. For example, too much sleep appears to be one factor and so does missing meals or eating certain foods like cheese.
Hormonal factors are also thought to influence the onset of attacks and their severity and one piece of evidence for this is the increased incidence of migraines in women. In part this is thought to be because of the effect of estrogen on the blood vessels and some studies have noted that there is a link between contraceptive pills (which contains estrogen) and migraines.
However, just to confuse matters studies have also shown that everyday activities like walking up stairs can trigger a migraine attack, as can exposure to loud noises, cold and heat, flashing lights and even stress.
Happily, there are several migraine medications available, although no one treatment is really effective in all cases. Over-the-counter medications are however seldom effective and, if you are unlucky enough to suffer from migraine headaches, you are best advised to ask your doctor for help in finding an answer which works for you.
