its very unlikely that your headaches are due to a stroke because a stroke or ruptured aneurysm causes a headache only 1 time (when you have it). migraines cause a very very small increase in the risk of stroke (we think) but there are many other risk factors for stroke that are much more important. if you are worried about your risk for stroke you should go for a consultation with a stroke neurologist---they can review your family history and do a few fairly simple blood tests and talk with you about your risk factors. several of the risks for stroke can be modified (smoking high cholesterol high blood pressure high blood suger) and will reduce your risk.
can having headaches increase my risk for a stroke?
