Not just a headache: migraine attacks similar to tiny strokes

RECENT research raises the possibility that migraine attacks may act like tiny strokes, leaving parts of the brain starved for oxygen and altering the brain in significant ways.

It has also been found that women who experience migraine while pregnant are significantly more likely to suffer a stroke, heart attack or other vascular problems during their pregnancy.

Chief Executive of the Migraine Association of Ireland Peter Murphy said the studies from the United States challenge commonly held perceptions of migraine as a completely benign disorder.

“These latest studies do more to smash the myth that migraine is just a headache,” he said.

Migraine affects about 400,000 people in Ireland and is the country’s most common neurological disorder. While it is not yet clear if the effects of migraine on the brain are permanent, the researchers warn that their findings have implications for people with migraine and the treatment they use.

They say it is imperative that people should not simply take medication to relieve pain but also should take measures to prevent their migraine in order to minimise any potential long-term effects.

And, in relation to the link between migraine and stroke, experts are calling for more in-depth studies in the area.

Director of the headache/migraine clinic at Cork University Hospital Dr Edward O’Sullivan said people with migraine and other risk factors for stroke should be trying their best to control the risk factors.

“Although migraine with aura is a recognised risk factor, other more serious risk factors include high blood pressure, high cholesterol, body weight, smoking diabetes and a prior history of cardiovascular disease,” he said.

Dr O’Sullivan said people with migraine need to view the condition in they same way they would view other risks as a medical problem that should be managed to improve life quality.

The association is holding an information day in the Clarion Hotel, Liffey Valley on May 20 at 2pm.
