In ancient Greece, the best-known remedy for a long-standing headache was to drill a small hole in the skull to drain supposedly infected blood. Fortunately, doctors today don’t resort to power tools to cure headaches, but we still have a lot to learn about this ancient ailment. In this Ted Ed lesson Dan Kwartler shares what we know (and don’t know) about headaches.
Today, we’ve classified headaches into two camps— primary headaches and secondary headaches. …we actually know much more about secondary headaches. These are caused by other health problems, with triggers ranging from dehydration and caffeine withdrawal…the origins of primary headaches remain unknown. Scientists are still investigating potential triggers for the three types of primary headaches: recurring, long-lasting migraines; intensely painful, rapid-fire cluster headaches; and, most common of all, the tension headache.
