Pain-Induced Changes in the Brain’s Opioid System May Explain the Limited Effectiveness of Opioid Therapy in Chronic Pain

Pain-induced changes in the brain’s opioid receptor system may explain the limited effectiveness of opioid therapy in chronic pain and may play a role in the depression that often accompanies it, according to a study from the NIH’s Intramural Research Program and McGill University. Although the study, published in the journal Pain, was conducted in rats, and the results of animal studies may not be directly applicable to people, the findings provide new insights into how the brain may respond to pain and opioids.
