Migraine and stroke relationship

migraine and stroke relationship

A migraine causes pain and sensory disturbances, but the changes inside the brain are usually temporary. The relationship between migraine and stroke is. Migraine and stroke are common neurovascular disorders which share . Several studies were performed to reveal the actual relationship of PFO and MA. Strokes and transient ischemic attacks (TIA), or mini-strokes, often have very similar symptoms to migraines with aura: visual disturbances.

Cervical artery dissection, another vascular cause of stroke, refers to a tear within the inner lining of an artery carrying blood to the brain. This may be due to quick movement of the neck traumatizing the artery.

Arterial dissection is more likely to occur in young persons with a history of migraine, and the most common presenting symptoms of head and neck pain may not be initially recognized as having another cause. The rare genetic condition, CADASIL, shows abnormalities of the small and medium sized arteries and clinical features of migraine with aura, TIAs, strokes, and eventually, vascular dementia.

Even under normal circumstances, there is growing evidence that migraine attacks perturb or activate the inner cell lining endothelium of the arteries, leading to release of substances involved in inflammation, and coagulation, and decreasing the ability of the vessel to fully dilate. B is for Blood Blockage of an artery from a clot may cause stroke, but if the blockage is temporary the result may be a TIA or aura-like episode.

When blood clots more than normal, this is referred to hypercoagulability. It may be caused by genetic, acquired, or lifestyle factors, such as cigarette smoking or use of estrogen containing contraceptives risk varies with dose.

One study of young persons with stroke showed that those with migraine with aura were over twice as likely to have at least one factor causing hypercoagulability as those with migraine without aura, or no migraine at all. For some persons use of daily aspirin prevents aura. Clots forming in or shunting through the PFO may be pumped to the brain and result in stroke, TIA, or aura-like episodes.

Wide variation of results from studies investigating the frequency of PFO in persons with migraine range: Clinical trials of PFO closure have not proven that this is an effective way to prevent migraine. Migraine and Heart Disease Most of the studies examining migraine and vascular disease have naturally focused on stroke, another brain condition. There is, however, also strong evidence that migraine increases the risk of heart disease, such as myocardial infarction heart attacks and angina.

The link between migraine and heart disease has been uncovered in men and women over a vast range of ages and across the globe. In several other study populations the risk of ischemic heart disease was doubled.

The mechanisms are unknown but likely involve inflammation, coagulation, and dysfunction of endothelial lining of the arteries. Tips for lowering risk of stroke and heart disease: Maintain a healthful diet, drink plenty of water, and get regular exercise and at least 8 hours of sleep Be evaluated and treated for conditions known to cause stroke and heart disease such as high blood pressure, high cholesterol and diabetes No cigarette smoking Use migraine preventive strategies.

In addition to decreasing attacks of migraine aura and headache, this may also prevent stroke.

The Migraine–Stroke Connection

In addition to the traditional migraine preventives, ask your doctor whether meds, which in addition to decreasing inflammation, decrease clotting such as daily aspirinor repair the endothelium such as a statin with Vitamin D are right for you Avoid use of estrogen containing contraceptives, especially if you smoke or have a personal or family history of blood clots.

Progestogen-contraception has less risk. J Stroke ; Migraine and hemorrhagic stroke: Migraine and genetic and acquired vasculopathies. Predictors of migraine subtypes in young adults with ischemic stroke: Second, common comorbidities between migraine and stroke can be present.

Lastly, some syndromes can manifest with both migraine-like headache and cerebrovascular disease. Future studies should be targeted on bidirectional influence of migraine on different stroke mechanisms and optimal prevention of stroke in migraine patients. There are increasing evidences for an association between migraine and vascular diseases and, in particular, between migraine and ischemic stroke, subclinical brain lesions, cardiac events, and vascular mortality.

Several underlying mechanisms may harbor beneath the connection between migraine and cerebrovascular disorders. Ischemic strokes in migraine sufferers may be categorized as cerebral infarction occurring during the course of a typical migraine with aura attack migrainous infarction and cerebral infarction of other cause coexisting with migraine migraine-related stroke.

In this review, we will discuss epidemiology, clinical feature and possible mechanisms of increased stroke risk in migraineurs. We will also provide evidences for managing patients with both stroke and migraine. An ischemic brain lesion must be demonstrated by neuroimaging in the appropriate territory of symptoms. The incidence of true migrainous infarction is very low. Migrainous infarction accounts for 0.
