Patent Foramen Ovale (PFO) Closure and Migraine Relief

We have previously noted a correlation between PFO presence and migraine headaches. Yesterday we saw one study that indicated the closure of the PFO to reduce frequency and severity of migraines.

Also, a link between migraine and stroke risk has been seen. One hypothesis is being investigated is that patients with migraine more often have a PFO and PFO make them more prone to stroke.

Let's take a look at another study that was performed to see if the closure of the PFO has any effect on headaches. In 2004 two groups of researchers from Belgium and Switzerland studies whether percutaneous closure (closing the PFO by a technique that does not require a major surgical procedure) would lead to few Migraines.

The Belgian group gave a questionnaire was given to people after PFO closure. The Swiss group gave a questionnaire both before and after the closure. Frequency of migraine was decreased in both studies after PFO closure.

These studies are critical. If PFO closure proves effective for Migraine prevention, that makes PFO a potentially correctable migraine trigger! Tomorrow we can take a look at another study that compared Migraine patients who had PFO closure with those who didn't. This could be great news to people who suffer headaches and they cannot figure out why. After we look at this next study I will share my experience when I was examined for a PFO.

Exercise! The legendary center fielder for the Boston Red Sox, Jimmy Piersoll used to say that running was the best exercise. I have done a lot of running for exercise in my life. It is great exercise although in my mind, it's boring and very tough our the knees. My favorite piece of exercise equipment is the Chuck Norris Total Gym that has been advertised on TV for years. It's easy to get hooked on! Once you do, you'll get in shape faster than you think possible.
