Migraine Term of the Day: Bilateral

Patient Expert
HealthCentral

When we're looking at Migraine and headache information, whether it's from our doctor, a book, or an online article, we sometimes come across medical terms that can be confusing.

Sometimes, it's easy enough to substitute another word or a short phrase for the medical term. At other times, substituting just doesn't convey quite the same meaning or takes more than a few words.

Some of you have expressed an interest in learning more of the medical terminology that comes up when discussing Migraine disease and other headache disorders. So, I'll be posting a "term of the day," probably a couple of times a week. If there are terms you'd like to have defined, please leave a comment to let me know what it is.

Today's term: Bilateral.

Bilateral simply means affecting both sides.

When discussing Migraines and other headaches, we generally see bilateral used to describe head pain on both sides of the head as opposed to unilateral head pain. For example, tension-type headache tends to be** bilateral**, whereas Migraine is more frequently unilateral.** Bilateral** is sometimes used to describe other symptoms as well. For example, the possible tingling and numbness of the extremities sometimes experienced with Migraine is often** bilateral**.
