Q: I am 20 years old, and I had a weird incident in August. I was sleeping, and I woke up with blurred vision. I had a terrible headache and felt like I was about to vomit. It lasted about 2 to 3 hours. I went to the doctor, and he didn’t find anything. Two days later I had the same thing happen. I went to a different doctor and again, nothing. Do you think it’s a migraine with aura?

PFOMigraine headaches are more common in patients with a small hole in the heart called a patent foramen ovale (PFO), and some research has indicated that closing the hole helps alleviate migraine. However, a recent study evaluating PFO closure in patients with migraine with aura showed mixed results. In the study of 107 patients (sign-in required) with migraine with aura who had not responded to previous treatment, PFO closure did not reduce the total number of migraine headaches within 1 year compared with medical intervention. However, the incidence of migraine with aura was decreased by the procedure.
