April 23, 2012 (CHICAGO) --New clues could help offer relief for people who live with recurring migraines. A new study suggests that people who have migraine headaches maybe more prone to "brain freeze," a painful condition which happens when you eat or drink something cold. The post says researchers presented the study at the Experimental Biology 2012 meeting in San Diego over the weekend. A study of 13 people following their reactions to sipping ice cold water. Scans show the sudden headache seems to be triggered by an abrupt increase in blood flow to a cerebral artery. The pain then disappears when the artery constricts. Researchers are hoping the discovery will lead to better treatments for headache sufferers, including those with migraines.
