There are two competing schools of thought when we talk about pain: either it's "all in your head" or "all in your body". Now, the new study led by University of Oxford researchers indicates that, instead, pain is an amalgam of the two.
To examine the interaction between depression and pain, Dr. Chantal Berna and colleagues used brain imaging to see how healthy volunteers responded to pain while feeling low.
Their findings revealed that inducing depressed mood disrupted a portion of the participants'' neurocircuitry that regulates emotion, causing an enhanced perception of pain.u00a0
In other words, as explained by Dr. Berna, "when the healthy people were made sad by negative thoughts and depressing music, we found that their brains processed pain more emotionally, which lead to them finding the pain more unpleasant."
The authors speculate that being in a sad state of mind and feeling low disables one''s ability to regulate the negative emotion associated with feeling pain. Pain, then, has a greater impact. Rather than merely being a consequence of having pain, depressed mood may drive pain and cause it to feel worse.
"Our research suggests depressed mood leads to maladaptive changes in brain function associated with pain, and that depressed mood itself could be a target for treatment by medicines or psychotherapy in this context," commented Dr. Berna.
