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.
