Abstract

While chronic pain is considered by some to be a CNS disease, little is understood about underlying neurobiological mechanisms. Addiction models have heuristic value in this regard, because both pain and addictive disorders are characterized by impaired hedonic capacity, compulsive drug seeking, and high stress. In drug addiction such symptomatology has been attributed to reward deficiency, impaired inhibitory control, incentive sensitization, aberrant learning, and anti-reward allostatic neuroadaptations. Here we propose that similar neuroadaptations exist in chronic pain patients.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A recent meta-analysis found that better social support was associated with less postoperative pain after breast cancer surgery.

    “better social support was associated with less postoperative pain after surgical management of breast cancer in a recent meta-analysis 97.”
  • The incentive sensitization theory proposes that repeated use of illicit drugs induces neuroadaptations leading to enduring sensitization of dopamine systems, hyperreactivity to drug cues, and pathological incentive salience manifesting as disproportionate motivation to pursue the drug.

    “This theory suggests that repeated use of illicit drugs induces neuroadaptations leading to enduring sensitization of dopamine systems with subsequent hyperreactivity in response to drug cues and a pathological degree of incentive salience, manifesting as a disproportionate motivation to pursue the drug (16, 18, 19).”

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.
