Research hasn’t shown that migraines are the cause of any other medical conditions. But they are linked to a number of ailments.
The link may be stronger if you have aura -- symptoms that come before your migraine. They can include flashes of light, blind spots, or tingling in your hands or face.
There’s little evidence that a migraine will trigger a stroke, or that both things will hit at the same time. Still, the chance of a stroke is higher in some people who have migraines, such as:
- Those who have aura
- People under 45
After 50, your odds of having a stroke from a migraine fall a great deal.
How often your migraines come doesn't appear to change your chances of having these conditions.
High Blood Pressure
Studies have yet to find a solid link between high blood pressure and migraines. There is evidence that hypertension may make you have more of those types of headaches.
If you get migraines, you’re at least twice as likely to have these. There may be a genetic link between the two. Researchers believe seizures may have the same genetic cause as migraines with aura. More study is needed.
Migraines make you more likely to have sudden hearing loss. That's an unexplained, rapid loss of hearing that happens over a few days. It’s extremely rare. However, folks who get those severe headaches get sudden hearing loss twice as often as people who don’t get migraines.
Depression and Anxiety
Migraines are common in people who have anxiety. If you have both, you're also more likely to have depression. Some research suggests that aura makes anxiety and depression more likely. But more study is needed.
If you have migraines, you may be more likely to have posttraumatic stress disorder (PTSD). One study found the likelihood of having PTSD is 5 times higher if you have migraines..
Some small studies suggest that women with migraines who get pregnant are slightly more likely to have problems like low birth weight, pre-term birth, and preeclampsia. Scientists continue to study these issues.
More generally, symptoms can worsen with pregnancy and may require a different treatment approach, which is why doctors suggest anyone with migraine talk to a headache specialist before they get pregnant.
