Women with migraines and visual symptoms may have higher stroke risk
...actor for ischemic stroke (stroke caused by a blot clot blocking blood flow to the brain). Few prior studies have addressed the different potential reasons for an association between migraine and stroke. Researchers analyzed stroke incidence among 386 women 15-to 49-years-old with a first ischemic stroke...Chemotherapy with bevacizumab increases risk of blood clots in arteries
...ed for all subgroups. Although death from [a blood clot in the artery] was uncommon, we did not capture functional disabilities from these events, and the risk factorsidentified in this study should be considered when making treatment decisions for individual patients, the authors write. ...Limiting stroke damage is focus of study
