Answer to Question 1

In the past, it was believed the migraines were caused by narrowing followed by dilation of blood vessels. This idea is now being replaced by the idea that a wave of cerebral electrical activity may cause the aura (or warning sensation), and that headaches develop when the wave reaches pain-sensitive blood vessels. The wave may be triggered by stress, hunger, hormone fluctuations, foods, alcohol, too much sleep, caffeine withdrawal, or noise. It has recently been shown that the neurotransmitter serotonin becomes depleted in the brain during a migraine attack.
