The peak age for migraines is 35-45. 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.
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.
