Treatment for headache, including the migraine headache, has significantly changed in the past decade. Causes for headaches, specifically of the migraine type, are still the subject of much debate. Headaches are currently divided simply as primary and secondary. Primary headaches are described as being "idiopathic," or not due to an actual disease process or external stimulus. Secondary headaches are classified as being due to an underlying disease/illness, such as sinusitis, or due to an external stressor, for example, trauma resulting in a closed head injury.
