'Brain freeze' is a nearly universal experience -- almost everyone has felt the near-instantaneous headache brought on by a bite of ice cream or slurp of ice-cold soda on the upper palate. However, scientists are still at a loss to explain this phenomenon. Since migraine sufferers are more likely to experience brain freeze than people who don't have this often-debilitating condition, brain freeze may share a common mechanism with other types of headaches, including those brought on by the trauma of blast-related combat injuries in soldiers. One possible link between brain freeze and other headache types is local changes in brain blood flow.
