Blood Flow Changes Offer Insight

1 Ice Cream Headache Sheds Light on Migraines

A new study involving thirteen healthy adults had the difficult task of drinking ice water through a straw that was placed in such a way as to induce the infamous “ice cream headache” found that the short-lived discomfort is likely due to increased blood flow in the anterior cerebral artery which may explain how migraines develop. Researchers hypothesize that because the brain is sensitive to temperature, the artery responds to the cold temperatures by dilating so that warm blood goes to the brain. As quickly as it dilates it constricts which likely protects the brain from high blood pressure levels which can be very dangerous in a closed structure like the skull. It is hoped that by understanding changes in blood flow could lead to the development of new treatments for migraines.
