It has been estimated that up to 20% of the population will consult a
physician with headache as their primary symptom.
Migraine headaches are particularly
severe "sick headaches" that affect 18% of women and 6% of men in the US; 23% of
women and 9% of men in Canada. The peak age for migraines is 35-45.
The U.S. National
Center for Health Statistics reports a 60% increase in the incidence of migraine in the
80's. Migraine can be a severe and disabling illness. To make a complicated problem
simpler, we assume that the triggers for two thirds of migraine headaches
come through the
mouth.
According to Family Practice ( Jan 12 1998;36) fewer than half of migraine
suffers seek help from their physicians. In Canada, it is estimated that 27 of 100 lost
work days is due to migraine headaches at an annual cost of $500 million per year.
Migraines can begin in children and affect females more than males. The average age of
onset is 20 and most people have 15 to 20 years of headaches before they disappear. New
headaches starting after the age of 45 should not be considered migraine until all other
causes have been ruled out. Some women have "premenstrual migraine" and only
experience headaches days before and during their periods.
