That "brain freeze" headache you experience when eating ice cream or other cold foods may be caused by a sudden change in brain blood flow, researchers report.

What's more, the new research might point to targets to treat other, more troubling forms of headache such as migraine, the U.S. team said.

In the study, the scientists monitored brain blood flow in 13 healthy adults as they sipped ice water through a straw pressed against the upper palate so as to trigger "brain freeze."

The results suggest that these transient headaches are triggered by a sudden increase in blood flow in the brain's anterior cerebral artery. Brain freeze disappears again when this artery constricts, the study found.
