    In the case of a teenage girl taking oral birth control, what is the risk of stroke if she has previously had migraines with effects in her arm, but no longer has those headaches?

      Anna,

      Thanks for your question. Here is the reply from Dr. Brown:

      Several studies suggest that migraine is a risk factor for stroke–this is particularly true for migraine with aura (preceding symptoms such as tingling, vision change or weakness that can occur just before the headache). The risk may be about three times as high as normal in people with migraine with aura, and about 1.5 times as high in migraine without aura.

      Oral contraceptives may slightly increase the risk of stroke, but this issue is somewhat controversial. This risk is very low with the use of the most contemporary oral contraceptives with low estrogen content. Particularly in young women who do not smoke and do not have hypertension, the risk is very low. This stroke risk is also increased in patients with migraine with aura. The recommendations regarding oral contraceptives in women with migraine with aura is complex. If the migraine with aura occurred in the past but are no longer occurring, they may be a candidate for oral contraceptives. If the migraine with prolonged aura episodes are ongoing, then one would likely recommend avoiding oral contraceptives.

    Hi Dr. Brown,

    Does having MS increase the risk of stroke?

    Thank you,
    Suzanne

      Dr. Brown says the evidence does not point to MS being a significant risk factor for stroke.
