Abstract

The mechanism of brain reorganization in pain chronification is unknown. In a longitudinal brain imaging study, subacute back pain (SBP) patients were followed over the course of 1 year. When pain persisted (SBPp, in contrast to recovering SBP and healthy controls), brain gray matter density decreased. Initially greater functional connectivity of nucleus accumbens with prefrontal cortex predicted pain persistence, implying that corticostriatal circuitry is causally involved in the transition from acute to chronic pain.

  • Chronic low back pain can become a complex condition in its own right, with persistent central nervous system changes and structural changes in the back.

    “There is growing evidence that cLBP, like other chronic pain conditions, can progress beyond a symptomatic state to a complex condition unto itself,109 involving persistent anatomical and functional changes in the central nervous system9, 93, 100 in addition to structural changes in the back (e.g., degenerative spinal changes, atrophy or asymmetry of para-spinal muscles).10, 11, 14”
  • vmPFC-NAc connectivity predicts the subsequent transition to chronic pain.

    “vmPFC-NAc connectivity predicts the subsequent transition to chronic pain [54].”
  • The exact NAc-vmPFC pathway tested was recently shown to predict the transition from acute to chronic back pain, demonstrating a functional role in pain chronification.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
