Brain Imaging for Chronic Pain

One of the reasons I’m so optimistic about the future is that right now, researchers are beginning to identify exactly which parts of the brain are involved in our experience of pain.

One of the key tools making this work possible is called functional magnetic resonance imaging, or fMRI.

An fMRI is slightly different from what most people think of as an MRI.  While regular MRI takes “snapshots” of what is going on in the body, fMRI shows patterns of blood flow in the brain.

Because the more active parts of the brain require more oxygen, fMRI shows us which parts of the brain are more active than others.

Using fMRI, scientists have been able to identify distinct patterns of brain activity in the brains of chronic pain sufferers.  These patterns of activity set chronic pain sufferers apart from healthy individuals.

In other words, you can actually see–in real time, from one minute to the next– how the brains of chronic pain patients are working differently than the brains of people without pain.

Although this work is still in the preliminary stages, I find this entire branch of research to be incredibly validating.

Someday, I believe, it will be much more difficult for doctors to dismiss chronic pain patients, because the effects of pain on the brain will be much better understood.   After all, it will be less a matter of taking our word for it when we’re talking about something you’ve seen on an fMRI screen.

And I believe that this deeper understanding, in turn, will lead to better and better treatments.
