Common migraine is a disorder involving recurrent headaches,
which may be accompanied by symptoms other than headache but
which rarely include a preliminary warning (called an aura). Migraine
headaches affect about 6 out of 100 people. They are
a common type of chronic headache. They most commonly
occur in women and usually begin between the ages of 10 and
46. In some cases, they appear to run in families. Migraines
occur when blood vessels of the head and neck spasm or constrict,
which decreases blood flow to the brain. Minutes to hours
later, the blood vessels dilate (enlarge), resulting in a severe
headache. Inflammation around the blood vessels also
occurs in some cases. Common migraine may be accompanied
by symptoms other than headache but only rarely includes any
preceding symptoms (aura). Migraines may also appear
as classic migraine (a migraine preceded by other symptoms)
and other rare forms. Multiple mechanisms trigger the
spasm and subsequent blood vessel dilation.
