Migraine linked to higher risk of stroke after a surgery is the latest finding of researchers studying the different health risks of migraine. The study finds that people with migraines suffer double the risk of a post-operative stroke compared to those without migraine. Given the high prevalence rate of people suffering migraine, the authors of the study believe that this finding has a significant effect on the health of the population.
The World Health Organization states that about 6.7 million deaths were a result of stroke in 2012. It occurs when blood flow to a particular area in the brain is blocked by a blood clot due to a blood vessel leak leading to brain cells oxygen starvation, resulting to long-term disability and ultimately, death.Heart attack and stroke have been two of life-threatening medical conditions that researchers are trying to help decrease using effective assessment tools and significant researches.
Migraine linked to stroke have long been considered in the past, the researchers say. However, the study is the first one to assess the risk of stroke that migraine causes after a surgery. According to the study, stroke risk appears the most mong migraine sufferers who experience aura.
Aura entails severe headache which includes a visual disturbance such as seeing flashing lights. Interestingly, the chances of a stroke in patients without aura is still 75 percent higher than those who never had migraine. However, experts assure that the risk for stroke is low in migraine sufferers, the Web MD says.
Lead researcher, Dr. Matthias Eikermann, says that most sufferers of migraine who had surgery never had a stroke, and that the study does not correlate surgery-related stroke with migraine. According to the Japan Today, even though the research suggests low risk of the occurrence of stroke, physicians should still inform their patients who have migraine about the potential risk. Migraine linked to stroke is not specifically a serious problem but patients deserve to hear possible side effects of their surgery.
