Heady stuff

New research out suggests that some migraine sufferers have been treated successfully by heart surgery. Does this mean that there is possibly a link between heart and head. And how does it evidence? The facts: A hole in the heart, known technically as a patent foramen ovale (PFO), is a minor defect in the wall that separates the two upper chambers of the heart, the atria. In most cases it causes no health problems, but can, in a small minority of people, lead to a stroke. It is also thought that failure completely to filter the blood of impurities in the normal way may result in migraines.
