Changes to one’s hippocampus, the brain’s memory centre, in response to prolonged pain could be an important factor for why some people develop depression in chronic pain, while others do not, according to a study.
“Our findings suggest that the hippocampus acts as a control centre that helps the brain regulate emotional responses to long-term pain. Depression is not inevitable — it depends on how this system responds over time,” co-lead author Jianfeng Feng, professor of computer science at the UK’s University of Warwick, said.
The study, published in the journal Science, analysed brain scans from population cohorts, including data from the UK Biobank, and a rodent model.
People living with chronic pain but without depression tended to show a slightly larger volume of and an increased activity in the hippocampus.
The changes were accompanied by an improved performance in learning and memory tasks, suggesting that the brain may initially mount a compensatory response to persistent​Changes to one’s hippocampus, the brain’s memory centre, in response to prolonged pain could be an important factor for why some people develop depression in chronic pain, while others do not, according to a study.
