The North American Antiepileptic Drug (AED) Pregnancy Registry is studying the effects of anticonvulsant medications in pregnancy. It was established in 1997 for pregnant women in the United States and Canada at the Massachusetts General Hospital in Boston, MA.

The information they provide during the course of their pregnancy provides future support to women diagnosed with epilepsy, mood disorder or chronic pain.

Our data gets better with every enrollment. If you have participated in the past and are pregnant again we would love to enroll you a second, or third…or seventh (for real) time. You can enroll at any time during your pregnancy. It’s never too late.

We need controls too. If you have friends or relatives who are pregnant we would love for them to participate also.

We recently enrolled women who learned of us from shared social media posts! Thank YOU!!!

We enroll pregnant women at any point during their pregnancy who do and do not use AED medications during pregnancy.

The more data we have the better the results.

The research involves telephone interviews and no changes to your routine.
