Pain is much on my mind lately. As recently as last November I wrote a post (Pain) in which I talked about my reluctance to use narcotic pain relief. Recent readers of Telling Knots will know that I have since agreed to take the stuff in spite of my objections. I still hate it and I still take as little as possible as infrequently as possible.
I wish there was a non-narcotic medicine for moderate to severe pain, and every now and then I spend some time on PubMed looking for answers. I stumbled across some fascinating findings today.
The image above and its caption are from a USA Today online article from April 10, 2013. (Please hover over the image with your mouse to read the explanation and photo credit.) This very exciting research used functional Magnetic Resonance Imaging (fMRI) to develop a “neurological signature” of physical pain.
A free preview of the original article in the New England Journal of Medicine can be see online here.
It is very, very early days and this research consists of four studies with a total of only 114 healthy subjects in the laboratory. Even so, the possibilities are tantalizing. The USA Today article quotes lead author Tor Wager: “”Many people suffer from chronic pain, and they’re not always believed. We see this as a way to confirm or corroborate pain if there is a doubt.”
The novelty of this study is not simply producing an image of what happens in the brain when pain is perceived, but in producing a combined signature that can actually measure pain. Furthermore, the researchers were able to distinguish physical pain from social or emotional pain.
As I said at the beginning of this post,I wish there was a non-narcotic medicine for moderate to severe pain, and obviously, I am not the only person interested in this: the study was partially funded by the (United States) National Institute on Drug Abuse, for example.
Aside from this being very cool research that may have many fascinating applications in the not-too-distant future, there is one aspect of it that I immediately hooked into. As Dr. Allan Ropper told USA Today, “This is beginning to open a new wedge into brain science,” Ropper said. “There may be completely novel ways of treating pain by focusing on these areas of the brain rather than on conventional medications which block pain impulses from getting into the spinal cord and brain.”
And that made me do a happy dance. Can you imagine how wonderful it would be to be able to treat pain (the whole pain, and nothing but the pain) without the side effects of narcotics? I know this is far in the future and I may not live to see it, but just the fact neuroscientists are working on it makes me very, very happy.
