Answer to Question 1
Migraines are believed to be neurovascular in origin, and are experienced more frequently by women than men. They are typically felt more on one side of the head. These painful headaches (i.e., migraines) may be accompanied by feelings of nausea and auras such as unusual lights or odors. It is a common belief that headaches, especially tension-type headaches (TTHs), are stress related. But does the research support this belief? Research suggests that TTHs are related to proximal (i.e., near term) stressors and that development of migraine headache patterns are related to distal (i.e., distant term) stressors.
Answer to Question 2
The most common type of headache is the tension-type headache (TTH). This type of headache, formerly known simply as tension headache, was renamed TTH in 1988 by the International Headache Society. TTH accounts for the vast majority of all headaches and is characterized by head pain that often has corollary pain in the neck, back, or other related muscle areas. It is different from migraine headaches.
