The researchers “identified men and women with migraine based on their prescription drug records and compared their risk of a heart attack and ischemic and hemorrhagic stroke before the age of 60 to the risks faced by people in the general population without migraine”. These findings, from Aarhus University, Denmark, were based on analysis of medical records collected from 1996 to 2018, from individuals aged 18 to 60.
Overall, the study suggests that migraines have a greater impact on women, beyond the question of numbers (migraines being predominantly diagnosed in women). Studies suggested that the increased risk of ischemic stroke – when a blood clot blocks a blood vessel to the brain – mostly affected young women.Ī new study tells a more complicated story: Both men and women who experience migraine headaches carry a similar elevated risk of having an ischemic stroke.īut it’s women alone who might carry “an additional risk of heart attack and hemorrhagic stroke”, when an artery bursts in the brain. However, the prevailing thought was that people diagnosed with migraine had a higher risk of experiencing a heart attack or stroke before the age of 60. It has long been believed that people who suffered migraines carry a greater risk of having a cardiovascular event. “These findings might facilitate the challenging diagnosis of a migraine.” Stroke risk In 2017, the Radiological Society of North America reported that migraine sufferers have significantly higher sodium concentrations in their cerebrospinal fluid than people without the condition. This could help scientists “better understand dopamine-based therapies for migraines as well as a patient’s behaviour during an attack”.
In 2017, University of Michigan researchers used PET scans of the brain to show that dopamine falls and fluctuates at different times during a migraine headache. This led to an independent observer from the Institute of Neurology, London, to conclude: “The new data show that after four millennia, migraine still has many more secrets to be uncovered.” Dopamine? In 2019, researchers from Harvard Medical School found increased thickness of two areas of the brain cortex in people who have migraines when compared to healthy controls.Īs well as showing “that there are some structural differences in the brains of people with migraine, the position of the changes could help to explain why some people with migraine have problems with visual processing even in between attacks”. In 2022, the American Academy of Neurology reported that women who get migraines may have a higher risk of pregnancy complications like pre-term delivery, gestational high blood pressure and pre-eclampsia. Whatever the case, migraines are a little-understood problem with a big impact on global health.
Other surveys have placed migraines sixth as a disabling condition. We know that about one in five women – and one in 15 men – suffer from migraines.Īccording to the Global Burden of Disease Study 2016 – an authoritative survey of health conditions across 195 countries – migraine attacks were the second-largest global contributor to years lived with disability. But a systematic review of 31 randomised controlled trials published last year found it safe and effective.
