Migraines may Increase 'Silent Stroke' Risk in Older Individuals

Migraines can create symptoms of vision disturbances that lead to pulsing neurological pain, often accompanied with movement, speech and sensory disturbances. A recent study shows that this relatively common health issue can increase the risk of "silent strokes," particularly in older individuals.

"I do not believe migraine sufferers should worry, as the risk of ischemic stroke in people with migraine is considered small," said lead study author, Dr. Teshamae Monteith, via WebMD. Monteith is an assistant professor of clinical neurology and chief of the headache division at the University of Miami Miller School of Medicine. "However, those with migraine and vascular risk factors may want to pay even greater attention to lifestyle changes that can reduce stroke risk, such as exercising and eating a low-fat diet with plenty of fruits and vegetables."

Silent strokes result in symptomless brain injuries created by blood clots that disrupt the flow to the brain.

For the study, researchers examined over 100 study participants with a history of migraines and nearly 450 who hadn't experienced them. Findings showed that 41 percent were men with an average age of 71 years, while Hispanics and blacks were at an increased risk of stroke at 65 percent.

Researchers used MRI scans to compare the brains of those with migraines and those without. Those who had migraines with auras showed an increased risk.

With this and other studies, researchers hope to push for better treatment of migraines to lower stroke risk and the problem in general.
