I worry about stroke also, Shel. My dad (surgeon, not a neurologist) says migraine with aura increases risk for some stroke by a small amount only - much less risk than smoking, the birth control pill etc. I hope your neurologist says similar thing.
And from NEUROLOGY 2005;64:1020-1026: Migraine, headache, and the risk of stroke in women
A prospective study
T. Kurth, MD, ScD, M. A. Slomke, C. S. Kase, MD, N. R. Cook, ScD, I.-M. Lee, MBBS, ScD, J. M. Gaziano, MD, MPH, H.-C. Diener, MD, PhD and J. E. Buring, ScD
Background: Migraine and headache in general have been associated with subsequent risk of stroke, primarily in retrospective case-control studies. Prospective data evaluating the association between specific headache forms and stroke are sparse.
Methods: A prospective cohort study was conducted among 39,754 US health professionals age 45 and older participating in the Women’s Health Study with an average follow-up of 9 years. Incident stroke was self-reported and confirmed by medical record review.
Results: A total of 385 strokes (309 ischemic, 72 hemorrhagic, and 4 undefined) occurred. Compared with nonmigraineurs, participants who reported migraine overall or migraine without aura had no increased risk of any stroke type. Participants who reported migraine with aura had increased adjusted hazards ratios (HRs) of 1.53 (95% CI 1.02 to 2.31) for total stroke and 1.71 (95% CI 1.11 to 2.66) for ischemic stroke but no increased risk for hemorrhagic stroke. Participants with migraine with aura who were <55 years old had a greater increase in risk of total (HR 1.75; 95% CI 1.02 to 3.00) and ischemic (HR 2.25; 95% CI 1.30 to 3.91) stroke. Compared with participants without headache, headache in general and nonmigraine headache were not associated with total, ischemic, or hemorrhagic stroke.
Conclusions: In these prospective data, migraine was not associated with total, ischemic, or hemorrhagic stroke. In subgroup analyses, we found increased risks of total and ischemic stroke for migraineurs with aura. The absolute risk increase was, however, low, with 3.8 additional cases per year per 10,000 women.

From Current Atherosclerosis Reports: Headache and the risk of stroke
Several studies have suggested that migraine is a risk factor for stroke. The association between migraine and the risk of stroke has been observed most often among premenopausal women but also in some studies among men. The association may be stronger among women who smoke and among women using oral contraceptives compared with nonsmokers and nonusers. Classic migraine with aura may be a more powerful predictor of stroke than common migraine without aura. Findings of a recent population-based study suggest that subclinical brain lesions are more common among migraine patients, particularly among those with aura, than among the control subjects. Two cohort studies have shown that chronic non-specific headache also is related to increased stroke risk. The effect of treatment of migraine and other types of headache on the risk of stroke is not known. Even though the relative risk of stroke may be fairly high among migraine patients, the absolute risk is usually low due to low baseline risk among young people.
I will call my dr about it on Monday. I have atrial fib which puts me at a slightly higher risk for strokes. Now, a migraine with a aura? Geez, how much more worse can my health get?
Thanks!
