Migraine Term of the Day: Dura

Patient Expert

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: Dura, aka Dura Mater.

The dura is the outermost of the three membranes that cover the brain and spinal cord. It is also the toughest and most fibrous of the three.** Dura** mater comes from the Latin for "hard mother."

We often see "dura" as part of other terms such as epidural, which means outside the dura. An epidural hematoma is an accumulation of blood outside the dura. Subdural means under the dura. A subdural hematoma is an accumulation of blood under the dura.
