Quizplus · Accepted Answer

Migraine headache is caused by changes in cerebral blood flow. This can result in the dilation and constriction of blood vessels in the brain, leading to the characteristic symptoms of migraine including severe headache, sensitivity to light and sound, nausea, and vomiting. Other factors such as stress, hormonal changes, and certain foods or environmental triggers can also contribute to migraines. Sunlight, accidents, and infected sinuses, although they can cause headaches, are not the primary cause of migraines.
