What is migraine?Ī migraine attack can have a wide range of symptoms. For example, CADASIL (a rare genetic disorder), and the auto-immune conditions antiphospholipid syndrome and Lupus, are linked to a higher risk of stroke, and people with these conditions are also more likely to have migraine. Some health conditions are linked to migraine. If you have migraine without aura you should be able to take the combi pill, unless you have other risk factors like smoking or being overweight. Because of this, women who have migraine with aura are not usually given the combi pill. Taking the combined oral contraceptive pill (combi pill) increases the risk of a stroke in women who have migraine with aura. They can also support you with making lifestyle changes such as stopping smoking, losing weight, healthy eating and exercise. If you have migraine, your GP or nurse can give advice on reducing your risk of a stroke from any other health conditions you may have, like high blood pressure, diabetes, atrial fibrillation or high cholesterol. However, the overall risk linked to migraine is still very low, and you're far more likely to have a stroke because of other risk factors like smoking and high blood pressure. If you have migraine with aura, you're about twice as likely to have an ischaemic stroke in your lifetime, compared to those without migraine. This tends to happen alongside prolonged aura symptoms, but is extremely rare. Migrainous infarction is the term given to an ischaemic stroke (a stroke due to a clot) that happens during a migraine. Occasionally migraine and stroke can happen together, but there is no evidence to suggest that one causes the other. The symptoms can sometimes seem similar, and they may share some underlying risk factors. The relationship between migraine and stroke is complex. This causes permanent damage to the brain, and can have long-lasting physical, cognitive and emotional effects.Ī migraine causes pain and sensory disturbances, but the changes inside the brain are usually temporary. In a stroke, the blood supply to part of the brain is cut off, killing brain cells. A stroke is due to damage to the blood supply inside the brain, but migraine is thought to be due to problems with the way brain cells work. However, the causes of the symptoms are different. Stroke and migraine both happen in the brain, and sometimes the symptoms of a migraine can mimic a stroke. Migraine diagnosis and treatment Understanding migraine and stroke
