Abstract

Objective: Fibromyalgia (FM) is considered to be the prototypical central chronic pain syndrome and is associated with widespread pain that fluctuates spontaneously. Multiple studies have demonstrated altered brain activity in these patients. The objective of this study was to investigate the degree of connectivity between multiple brain networks in patients with FM, as well as how activity in these networks correlates with the level of spontaneous pain. Methods: Resting‐state functional magnetic resonance imaging (FMRI) data from 18 patients with FM and 18 age‐matched healthy control subjects were analyzed using dual‐regression independent components analysis, which is a data‐driven approach for the identification of independent brain networks. Intrinsic, or resting‐state, connectivity was evaluated in multiple brain networks: the default mode network (DMN), the executive attention network (EAN), and the medial visual network (MVN), with the MVN serving as a negative control. Spontaneous pain levels were also analyzed for covariance with intrinsic connectivity. Results: Patients with FM had greater connectivity within the DMN and right EAN (corrected P [ P corr ] < 0.05 versus controls), and greater connectivity between the DMN and the insular cortex, which is a brain region known to process evoked pain. Furthermore, greater intensity of spontaneous pain at the time of the FMRI scan correlated with greater intrinsic connectivity between the insula and both the DMN and right EAN ( P corr < 0.05). Conclusion: These findings indicate that resting brain activity within multiple networks is associated with spontaneous clinical pain in patients with FM. These findings may also have broader implications for how subjective experiences such as pain arise from a complex interplay among multiple brain networks.

  • Chronic pain is associated with elevated functional connectivity among the DMN, FPN, and SN.

    “Not only does each network independently demonstrate changes in functional connectivity in response to different types of chronic pain stimuli, it has been demonstrated that there is elevated functional connectivity among the DMN, FPN, and SN in individuals suffering from CMP [12,13,14,15,16,17,18].”

    From Graph theory analysis of induced neural plasticity post-Acceptance and Commitment Therapy for chronic pain (2020) · cites this paper as [16]

    The Results (page unavailable) report elevated connectivity within the DMN and right executive attention network—a frontoparietal network—in fibromyalgia, as well as increased connectivity between each of those networks and the insula with greater spontaneous pain. The paper does not evaluate the salience network as a network or demonstrate elevated connectivity among all three networks. (LLM, conf=0.87)

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.
