An Introduction to Migraine Causes and Symptoms
Around two-thirds of migraines occur in women (because of hormone fluctuations). They actually happen more often than diabetes, epilepsy and asthma combined. Many factors can go into causing a migraine, and diagnosis is largely symptomatic. The symptoms of a migraine can include episodes of headache pain (which is usually focused on one side of the head), accompanied by nausea, sensitivity to light and sound, and (in around 20% of migraine sufferers) a visual aura, or a presence of a white zig-zag like light in one’s field of vision.
Migraines are generally not a threat to a person’s overall health, although they can interfere with one’s everyday living. The true causes of migraines are not full understood at this time, although there are some things that are more common in people who experience them.
While many people’s migraines are severe, not all severe headaches are actually migraines, and some migraines can be quite mild. However, migraines are not always a sign of a stroke or a tumor, and your physician will reassure you of this. Some believe that a migraine is a combination of a genetic vulnerability and environmental factors that stimulate the overactive system.
Migraines are commonly described as a throbbing or pounding pain in the head. They can be worsened by some activities and generally sufferers are adversely affected by light and noise. Many migraines can also be caused from dehydration.
For both males and females, the rate of severe headaches and migraines is highest among those people aged 25 to 44 years and decreases with age. The frequency of migraines significantly increases during a woman’s perimenstrual period, and menstrually related migraines can be of a longer duration and greater frequency with longer lasting disability than any non-menstrual migraines.
